bull terrier: a dangerous or
a defamed breed?

Abstract
After more than a
century as America's icon
dog1 the American Pit Bull
Terrier since 1980 has
developed a notorious
reputation as a dangerous
breed with consequent
restrictions placed upon it
by various jurisdictions in
Australia and elsewhere.
Studies in the USA have
indicated that the "pit
bull" is responsible for a
large proportion of human
fatalities resulting from
dog attack, but their data
are flawed by methodological
shortcomings. Data on
frequency of dog attacks by
breed in Australia reveal
the pit bull terrier to be
exceeded by several other
breeds. Of about 14 human
fatalities in Australia over
the last two decades, none
has involved a dog verified
to be a pit bull terrier.
The evidence does not
sustain the view that this
is a uniquely or
particularly aggressive and
dangerous breed, and there
is no support in its attack
record for breed specific
laws aimed to control it.
Dogs are kept by
approximately forty percent
of Australian households.
They confer many benefits
upon their owners and are a
source of great emotional
satisfaction to a large
number of people. Dogs are
also a threat to the
community in that their
bites injure a large number
of people every year. A
small number of these
attacks cause very serious
human injuries, and even
fatalities. Dog attacks,
then, represent a
significant public safety
issue that needs to be
addressed by state and local
governments.
Breed specific
approaches to dog control
Many jurisdictions in
Australia and overseas have
introduced breed specific
laws aimed to restrict or
ban ownership of breeds
deemed to be particularly
dangerous to people. Such an
approach may be based upon
either of two beliefs:
the breed in question has a
record of bite frequency
which demonstrates its high
level of aggression towards
people;
the breed has a potential to
be dangerous because of its
physical characteristics and
its functional history.
In Australia only one breed
that actually exists here in
significant numbers has been
subjected to breed specific
controls: the American Pit
Bull Terrier (APBT).
Restrictions on this breed
were imposed by the
Commonwealth in 1991 largely
on the basis of the second
belief, relating to its
dangerous potential .2 At
that time the Dangerous Dogs
Act 1991 had just been
passed in the UK after a
couple of very serious dog
attacks attributed to APBTs,
and the news media in
Australia and Britain
introduced the breed to
public notice with lurid and
sensational accounts of its
background, capabilities and
character.3,4,5,6 This
character, once given, has
set solidly in the minds of
the public, the media
themselves, and authorities
at various levels of
government. It is, perhaps,
noteworthy, that in 1991,
when the Commonwealth import
ban was announced, there had
been no recorded attacks
upon people by APBTs in
Australia, while dog attacks
in general were, as now, a
considerable menace to
public safety. It is also
noteworthy that one
rationale offered for the
Commonwealth ban was that
the UK had banned the dogs,
and that they are
"fighting" breeds which
ipso facto proves them
to be uniquely dangerous
among dog breeds. That two
of the four banned breeds,
Dogo Argentino and Fila
Brasileoro, were developed
as hunting, not fighting,
dogs7 has never caused any
difficulty or embarrassment
to the British originators
of the mistake, or to its
Australian imitators.
In 1998 the NSW government
introduced breed specific
restrictions of a minor kind
on the APBT, and the other
three breeds banned from
import by the Commonwealth
(Companion Animals Act
1998). In 2001 the
governments of both Victoria
and Queensland introduced
harsher restrictions aimed,
in the latter case,
eventually to eliminate the
breed. In all states these
measured were announced
during periods of intense
news media focus upon the
"dangerous dog" issue
occasioned by a number of
serious attacks, especially
upon children. Of interest
is the fact that, while
public submissions were
called for before drafting
of legislation, no attempt
was made by relevant
ministers or premiers to
justify the measures by
reference to the APBT's
record of attacks in the
respective states, or
indeed, to any data touching
the frequency and severity
of dog bites by breed.
Rather, naïve general
comments about the breed's
alleged history combined
with myths about the breed's
nature sufficed for the
occasion of the bills'
introductions to
parliaments.8,9 The
Queensland Government did
reveal that the large
majority (218 of 253) of
public and specialist
submissions argued against
breed specific legislation
(BSL)8, but they were
ignored, and it is suspected
on the basis of
press-releases early in the
process that the decision
had already been made.
Dog attack data
BSL in Australia has
been enacted on the basis of
the APBT's reputation and
beliefs that it is a
dangerous breed. As
discussed above, that belief
can come from assumptions
about the breed's attack
record or about its
aggressive potential. What
is its attack record? It is
accurate to say that nobody
really knows, but it depends
on the region of the world
under discussion. It would
be reasonable for Australian
parliaments to legislate on
the basis of the situation
in Australia, but the breed
import ban was justified by
the alleged record of the
dogs in the USA and UK .2 At
first glance data from the
USA indicate that the "pit
bull" is the country's most
dangerous dog breed. Sacks
et al. 10 present data
showing that the "pit bull"
and its crossbreeds is
accounted for approximately
32% of human dog attack
fatalities between 1979 and
1998, for which breed of dog
was known (238 deaths). This
study updates an earlier
one11 that for the years
1989 through 1994 had "pit
bulls" accounting for 22% of
fatalities. These data,
however, are seriously
flawed. In The USA "pit
bull" does not mean APBT,
but is a generic term which
includes all the bull and
terrier breeds, and
sometimes the other bull
breeds such as Boxers, Bull
Mastiffs, American
Bulldogs12
It has also been found that
where there is a bad dog in
the public consciousness,
any stocky, short-haired dog
involved in an attack is
called a pit bull by
witnesses, including police
and dog officers, and any
large black and tan dog is a
German Shepherd. 13 Even
experts cannot always tell
whether a dog is a pit
bull.12 U.S. city
authorities frequently
enlist unenthusiastic
veterinarians to identify
dogs as pit bulls, a task
for which most of them are
ill equipped.14 For these
reasons the American Dog
Breeders Association has
wholly abandoned trying to
calculate pit bull bite
rates, and discounts
findings which use this
approach ( letter to author
1992).
Sacks et al.10
indicated that they recorded
more than 327 fatalities but
claimed these represented
only 74% of actual
fatalities. More seriously,
breed identification is
based upon newspaper
accounts, which the authors
characterize as unreliable.
They also are aware that the
media may selectively report
deaths caused by a notorious
breed. Of interest is the
fact that recorded deaths in
the USA have maintained a
fairly steady rate since
1980, yet the breeds of dog
primarily responsible have
changed through time. Since
1992 the Rottweiler has
killed twice as many people
as has the "pit bull"
(30:15), but between 1979
through 1986 it was
responsible for only two
deaths. This fatality record
tracks breed registration
figures: in the earlier
period 24,195 Rottweilers
were registered with the
American Kennel Club, while
there were 692,799
registrations from 1991
through 1998.10
Australia does not have very
much data on frequency of
dog attack by breed. Indeed,
we do not have good data on
the frequency of dog
attacks, as is evidenced by
the methodologies employed
to estimate their numbers in
the various published
studies.15,16,17 Dog bite is
not a notifiable injury, and
while some hospitals and
local councils record dog
bites and sometimes
assessment of the breed
involved, others do not. In
addition, an unknown, but
probably high, proportion of
attacks are treated by GPs
or at home and never
reported to a central
authority. Since 1997 the
NSW Department of Local
Government has required
councils to report all dog
attacks to head office, but
it is unlikely that
compliance or accuracy
approaches 100%.
Never-the-less, these are
the best data available in
Australia.
The data show that from 1997
to 2000 inclusive there were
829 injuries to people
caused by dogs reported to
councils in NSW. The breeds
responsible for the majority
of attacks were crossbreeds,
unknown breeds, Cattle Dog
types, German Shepherd
types, and Collie types. It
is noted that breed was not
validated and in most cases
was identified by one of the
people involved. Categories
are types rather than
specific breeds because
identification is imprecise.
Bull Terrier types were most
likely to attack other
animals. 18
These injury figures
represent only a proportion
of people bitten by dogs.
Other studies indicate much
higher numbers. For
instance, 2,232 people were
treated for dog bites in the
four years between 1998-2001
in five Brisbane hospitals,
more than double the whole
NSW total for a similar
period.19 Thompson15,16
estimated on the basis of
injury data from Adelaide
that as many as 30,000
people could be injured each
year by dogs in Australia.
This could be an
underestimate, as American
data show injuries from dog
bites to 3 per 1,000 people
per year.20 If the same rate
of attack occurred in
Australia, we would
experience 60,000 dog bites
requiring medical treatment
per year. This bite rate
probably is not reached in
Australia, however. The USA
experiences some 20 -30
human fatalities from dog
attack each year,10,21 while
for Australia the rate is
about 0-2 cases per year. 20
The US fatality rate is,
therefore, about double that
of Australia. Thompson's 16
figure of 30,000 injuries
matches this observation,
though in light of other
Australian studies it seems
an extreme figure. This
highlights the lack of
knowledge surrounding the
whole issue of dog attacks
in Australia. Thompson's
Adelaide data record the
following percentages of
injuries caused by specific
breeds: German Shepherd
25.3%, Bull Terrier 13.6%,
Cattle Dog 13.6%, Dobermann
11.7%, Rottweiler 9.1%.
Breeds again were identified
by people involved in the
attacks, so they are not
verified or reliable. It
should also be noted that
the attacks occurred prior
to 1991, and relative breed
populations will have
altered over the 11 years
since then, as dog breeds
respond to fashion and other
considerations.
The Victorian Bureau of
Animal Welfare conducted a
study of dog bites in public
places between 1997 and 1999
inclusive.17 The study
included six municipalities
and gathered data from
reports of dog attacks in
public places. A total of
413 injuries to people was
recorded, 20 of them being
serious enough to require
two or more sutures. There
were 46 breeds (including
crosses) responsible for
attacks with the following
order of precedence: German
Shepherd 127, Cattle Dog 90,
Rottweiler 71, Kelpie 40,
Staffordshire Bull Terrier
40, Bull Terrier 37,
Crossbreed 35, Labrador 33,
Dobermann 26, Boxer 26, Jack
Russell 22, Rhodesian
Ridgeback 22, Border Collie
21, American Pit Bull
Terrier 21. Another
Victorian study of hospital
presentations for dog bites
found 1,112 cases in the two
year period, January 1996 to
December 1997.22 Breeds most
commonly recorded in these
attacks were Kelpies,
Crossbreeds, Border Collier,
Fox Terriers, Cattle Dogs,
German Shepherds, and Jack
Russell Terriers. These
breeds may reflect the
largely rural nature of the
sample (71% of
municipalities returning
data).
An informal survey of dog
bites by breed among
Queensland councils was done
by the Endangered Dog Breeds
Association23 in 2001.
Replies to enquiries were
received from 19 councils,
excluding Brisbane City and
the Gold Coast. A total of
750 dog attacks was recorded
for a 12 month period, and
of those, 3 were attributed
to APBTs. Separate data from
the Gold Coast City Council
area recorded 162 dog
attacks, 3 of them being by
APBTs. These data are
supplemented by the register
of dogs declared dangerous
for an attack or other
aggressive behaviour by the
Brisbane City Council as of
1995. There were 751 dogs on
the register with the
following breeds
predominant: Cattle Dogs
200, German Shepherds 185,
Bull Terriers 76,
Rottweilers 69, Kelpies 43,
with 9 other breeds making
up the list. Two of the dogs
were APBTs. It seems
impossible that no
crossbreed dogs were on the
register.
The situation is similar in
New Zealand. The Department
of Internal Affairs surveyed
dog attacks since 1996 in 47
council areas, representing
73% of the nation's
population.24 Of those, 23
councils recorded attacks by
breed, but did so for less
that half of the attacks.
Furthermore, breed
identification (which
included cross-breeds) was
not validated, being
reported by various
witnesses and with an
inconsistency of terminology
to describe breeds between
councils. The data reveal
that Pit Bull Terriers were
responsible for 9.6% of
attacks for which breed was
recorded behind
Staffordshire Bull Terriers
(15.5%), German Shepherds
(14.4%), Labradors (13.9%),
Bull Terriers (12.6%), and
Rottweilers (10.6%). In the
U.S. the 3 bull terrier
breeds would be called "pit
bulls" and would account for
37.7% of attacks, far ahead
of the second ranked breed.
This creates difficulties in
transferring breed attack
records between countries.
These various data indicate
two things quite forcefully:
a relatively small number of
dog breeds contribute a
large proportion of all
attacks; and the APBT is not
one of the breeds. It may be
claimed that APBTs do not
cause a great number of
injuries to people, but that
the injuries they do inflict
are very severe ones. It is
true that a small number of
serious injuries have been
caused in Australia by APBTs.
While the news media give
heavy coverage to some
serious dog attacks, which
they often attribute to
APBTs (incorrectly in most
cases investigated by the
author), it often is not
realized that an estimated 6
people are admitted to
hospital every day in
Queensland alone suffering
from dog bites.19
Impressions of which dogs
are most dangerous implanted
by episodic news media
stories are not very
reliable or valid. In the
last two decades or so there
have been 14 human deaths
caused by dog attacks in
Australia - these data come
from memory, newspaper
clippings, and consultations
with people in the pet and
animal welfare institutions.
A variety of breeds and
crossbreeds was involved,
but not one fatality was
caused by an APBT. The
possible exception was the
case of Barbara Stringer of
Toowoomba who was killed in
1995. The dog has often been
claimed to be an APBT, but
it was registered as a
Labrador cross, and to
experienced eyes it looked
like a crossbreed. The
animal welfare officer who
cared for the dog until its
death affirmed in writing
that the dog was some type
of bull breed cross. It may
have been an APBT cross, but
that is far from certain.
Potential to be
Dangerous
It is a truism that all
dogs can bite and that dogs
of any breed can be
dangerous. Indeed, American
records25 indicate that
several toy breeds have
killed infants, and a
recent unpublished
Australian study recorded
very serious injuries to
children inflicted by toy
breeds (Courier Mail 2002).
However, it often has been
claimed that the American
Pit Bull Terrier and other
"fighting" breeds are
especially dangerous because
of human breeding selection
for physical and
temperamental traits
functional in pit
fighting.26 "Bred to kill"
is a phrase so often used
that it has become a cliché.
Behavioural details are
supplied by over a decade of
news media coverage to
illustrate this killing
disposition. It is said that
once a "pit bull" initiates
an attack it goes into a
sort of trance and cannot
desist until its victim is
dead; that the breed has
"locking jaws" (this view
probably holds that the dog
can unlock the jaws, but
bystanders cannot - this
point is never addressed);
that "pit bulls" can exert a
bite force of some fabulous
number of psi, sometimes
2,000, sometimes 4,000, but
far more than dogs of other
breeds; that this bite force
comes from the extreme
development of the cheek
muscles controlling the jaw.
If common sense and an
elementary knowledge of
canine cranial anatomy were
not enough to debunk these
myths, the anatomical
dissection work of Lehr
Brisbin and colleagues at
the University of Georgia27
and Bonnie Dalzell
(University of Pennsylvania)
is. They have shown that
there is nothing in the
skeletal structure of the
APBT jaw that is any
different from that of any
other dog in respect to
locking. Hanging on with the
jaws, of course, is a
function of jaw muscles. Any
animal may bite and hang on,
as anyone who has been
bitten by a budgerigar or
human toddler knows. Dogs of
all sorts may do this too,
but the "lock" is simply a
matter of muscles held in
contraction entirely under
the voluntary control of the
biter. Nobody knows the
relative biting power of
various breeds of dogs, as
it is a difficult trait to
test under laboratory
conditions. Anecdotal
evidence from people
experienced in having their
sleeved arms bitten by
schutzhund trial dogs
suggests that APBT don't
bite harder than other
breeds used, but that hard
biting is an individual, not
a breed, characteristic.1
Dalzell's anatomical
investigations found that
APBTs do not have greater
jaw muscle mass than German
Shepherds with similar sized
skulls.28 The masseter
muscle is the major jaw
muscle concerned, and this
attaches to the rear of the
jaw and along the top of the
side of the skull. Mammals
with very large masseter
muscles usually have
insufficient cranial area to
which the masseter can
attach, so a crest of bone
(the sagittal crest) is
developed along the top of
the skull. German Shepherds
have such a crest, but APBTs
do not. This means the
shepherd masseter muscle is
long, while the APBT
masseter, attaching lower on
the skull, bunches up and
bulges, giving an impression
of great development. In
fact, the muscle volumes are
similar, and there is no
anatomical indication that
the APBT should bite any
harder than another dog of
equivalent size.
Canines, relative to other
carnivores, have weak jaws,
but domestic dogs of most
breeds have more than
sufficient bite power to
inflict serious damage to
human tissues.28,29 When
hunting large mammals,
canids, like wolves, kill
their prey by ripping with
multiple bites and bleeding
the victim to death. The
cats, by contrast, use great
bite force to crush the
throat or to puncture the
brain. Serious dog attacks
on people are characterized
by multiple slashing bites,
sometimes accompanied by
shaking to tear tissue. Are
APBTs any different from
other dogs in their attack
patterns?
The APBT has been used as a
pit fighting dog for well
over a century, and some
strains have pedigrees going
back that far.30 However,
the breed developed
originally not as a fighting
dog, but as a stock-control
dog, and for its whole
history the proportion of
dogs used for fighting was
tiny, the majority being
working farm dogs or family
companions.1 Many strains
have been and continue to be
used for fighting, and
breeding selection has been
made on the basis of
successful pit fighting
traits. Pit dogs fight, not
by inflicting multiple
slashing bites, but by
taking the most advantageous
hold possible and shaking. A
hold will only be released
if a better one can be
taken. Punishment by the
other dog typically does not
cause a release of the hold.
This is the origin of the
"locking jaws" myth. There
have been attacks on people
by APBTs, and in some of
them it has proved very
difficult for bystanders to
get the dog to release its
hold on the victim.12 If
serious injury results,
especially to a child, the
bystanders tend to give
lurid accounts to the news
media of a crazed dog with
locked jaws oblivious to
being beaten with pieces of
wood, iron bars etc. A small
number of such attacks,
reported sensationally by
news media, is responsible
for the demonic reputation
of the "pit bull" held by
those whose only knowledge
of the breed has come from
such reports. It is not
true, however, that all APBT
attacks are of a lethal
nature intended to kill. The
great majority are trivial
nips, no worse than bites by
other breeds.331
Genetics
"A fighting dog is bred
to be savage and aggression
is in the genes." This is a
typical statement of animal
welfare office-holders,
politicians, and
journalists.32,33,34 Its
frequent repetition has
convinced many uninformed
people, the general public,
of its truth. It has,
therefore, been possible for
Australia's three levels of
government to enact
legislation specifically
against the APBT without
arousing any significant
public or media opposition.
Is the statement valid?
A fighting breed, or any
other dog breed, cannot be
savage, if "savage" is meant
to describe a dog that is
indiscriminately aggressive
towards all it meets, human
or other animal. It is not
practical to have a dog of
this disposition, and no
breed exhibiting such a
character could have been
developed. A fighting breed
may, however, be developed
to exhibit traits useful in
pit fighting, which may
include toughness, stamina
and determination.
Aggression must be present
to the degree that the dog
must have a drive to
dominate its opponent. Many
pit dogs, therefore, are
aggressive towards other
dogs, but many are not. That
is, some famous pit fighting
dogs were quite mild in
their social encounters with
other dogs outside the
pit.35 Of the useful pit
characteristics, the one
chiefly under selection has
been determination, which
fanciers call gameness:
determination to persist in
a task regardless of
difficulty. This, more than
fighting ability, has been
the admired trait, and the
one that distinguishes the
APBT in so many fields of
endeavour.1
Selective breeding for pit
fighting characteristics
has, of course, been based
upon phenotype. It is a
dog's phenotype that is
successful in the pit, or in
herding sheep etc, but
selective breeding of
phenotypes affects
genotypes. This means that a
population of dogs under
tight selective breeding for
a set of traits can develop
a high frequency of alleles
that predispose the dogs to
the appropriate behaviour.
The best example, perhaps,
is the eye-stalk motor
pattern of the Border
Collie, which appears to be
"hardwired" in that breed's
genotype.29 It may be that
the APBT has alleles that
predispose it to aggression
towards other dogs, though
this is not established by
more than assumption. There
is a reasonably strong
literature showing that many
canine behaviours, including
aggression, have a genetic
basis.36 High levels of
idiopathic aggression have
been found in Cocker
Spaniels, English Springer
Spaniels and Bernese
Mountain Dogs, and in the
latter this trait was traced
back to two sires.26 The
former breeds top lists of
dogs presented to a sample
of American behaviour
clinics for aggression.37 In
the case of Cocker Spaniels,
there may be no neurological
pathology (often called
Cocker, or Springer, Spaniel
Rage) so much as dominance
aggression. A study37found
an association between
Cocker Spaniel temperament
and owner personality, which
indicates that some owners
bring out the worst in the
genetic potential of their
dogs, quite unintentionally.
Nobody desires aggressive
Cocker Spaniels, but several
breeds have been produced to
function as guard dogs, and
in them a level of
aggression towards strangers
is sometimes seen as
desirable. Such breeds are
the Rottweiler, the German
Shepherd, the Dobermann and
the Akita36, and they have
been found to be among the
top breeds exhibiting
territorial defence.38 The
APBT is not a guarding
breed, and while some of
them may be used for that
purpose, it is not an aspect
of the breed's functional
history. Indeed, the author
visited yards of two APBT
breeders who kept
Rottweilers to guard the
APBTs against theft. While
the APBT has been under
selection for dog-aggression
and gameness, it has also
been under complementary
selection for stability and
tractability with people. A
moment's consideration will
reveal why. Pit dogs must be
in a very close relationship
with the handler in the
weeks of conditioning for a
match. They must fight in a
small pit with a handler,
the opponent's handler, and
a referee, this while at a
high level of excitement and
possibly injured.35
Furthermore, traditionally
the dogs had to be inspected
and washed by the opposing
camp, which once upon a time
involved a stranger, called
a taster, licking the dog
all over to detect any
poisons applied to its coat.
This is not something one
does to a dog displaying
indiscriminate aggression.
Given this selection, why
are some APBT, and dogs of
other breeds, dangerous in
being aggressive towards
people? Genes do not cause
behaviour.29 Behaviour, like
bodily structure, is an
outcome of complex
interaction between genes
and many environmental
variables, the environment
including the cellular
tissues in which other cells
are developing, as well as
the external environment. It
is not just a matter of
training or abuse: a dog
handled cruelly becoming
unapproachable, for
instance. Because a puppy is
born with its brain growth
incomplete, its sensory and
other learning experiences
determine the actual
structure of the brain and
the degree to which neurones
form networks of connection.
Socialization and exposure
to various stimuli at
appropriate critical periods
of growth affect the brain
and determine the
temperament. Even the
"hardwired" for herding
Border Collie will not
develop the breed-typical
motor patterns of herding
unless it is exposed to the
appropriate external stimuli
at the critical age.29 Even
though many canine
behavioural traits may be
under genetic influence,
heritability for most is
low,36 which reflects the
importance of environment in
developing the behaviour.
The fact that many dogs
exhibit breed stereotypical
behaviour is as much to do
with human expectations and
associated treatment of the
dog as with the dog's
behavioural genetics.29 The
case against APBT having
genes determining aggression
was compelling enough to be
accepted by the Alabama
Supreme Court in August 2002
in a case brought by the
Washington Animal
Foundation.39
Discussion
Human expectation and
socialization is one of the
reasons for the reputation
for unique savagery the APBT
has, particularly in
America. The 1980s to 1990s
was a period of pit bull
panic in the USA,1 but this
was not a perception created
only by lurid news media
coverage of severe attacks.
APBTs, like all dogs, given
their behavioural
plasticity, can be made
aggressive by human agency,
either unwittingly or
deliberately. There is some
evidence to support the
popular view that
anti-social elements have
utilized APBTs as guard dogs
or to intimidate people.6
Many studies addressed the
issue of "pit bulls" and
their involvement in dog
attacks, including
fatalities.10,21 A general
finding was the "pit bulls"
were responsible for a
greatly disproportionate
number of attacks, including
fatalities. There are two
methodological failings with
these types of study, which
many of them acknowledge.
Identification of the breed
of an attacking dog is
seldom reliably assessed,
and usually is taken from
media reports10. Not only
are the news media more
likely to report attacks by
breeds like "pit bulls" and
to wax and wane in their
interest in dog
attacks,20,40 but in periods
of heightened panic, attacks
by almost any dog are
attributed to "pit
bulls".13,41,42 These
authors provide specific
cases of heavily reported
attacks by "pit bulls" that
in fact were not pit bulls.
A cursory examination of
Australian media reports
would reveal this to be the
general rather than episodic
situation. The second
methodological problem with
many published studies is
that in calculations of the
relative bite record of
various breeds, neither the
numerator (attacks by the
breed) nor the denominator
(numbers of the breed in the
population) is known.20 We
have very little idea how
many APBTs live in any
Australian state. The breed
is not registered by canine
councils, and because of the
long-standing threat of
restrictive legislation,
very few of the dogs are
registered by their breed
with local councils. NSW has
about 200 APBT registered
with councils,43 but there
probably are thousands in
the state. The Gold Coast
City Council has a handful
of APBT registered as that
breed, but "thousands"
within the jurisdiction.44 A
complicating factor in
American studies is that
"pit bull" there does not
refer to APBT, but to all of
the bull breeds and their
crosses, and even to
unrelated dogs like Shar
Peis. These facts render
questionable study findings
that the APBT is a
particularly dangerous
breed. To illustrate this
problem, if US criteria of
pit bull identity were
applied to Australian
fatality data, 5 or 6 of the
dogs involved in 14 human
deaths would be classed as
"pit bulls", yet at most one
of the dogs was an APBT
(author's file of media
reports of fatalities).
The apparent differences in
attack records of "pit
bulls" in America and
Australia may have several
explanations:
It may be simply that "pit
bull" is a generic category
in America, but tends to
refer to a specific breed,
the APBT, in Australia;
It may be that the two breed
populations exhibit average
genetic differences relating
to predisposition to
aggression. This is
possible, given that the
Australian population
descends from approximately
70 dogs imported from
America in the 1980s45 from
fighting yards;
It may be a sociological
question not related to the
nature of the dog breed. In
as much as both criminals
and householders fearful of
criminals may desire
powerful and aggressive
dogs, relative rates and
profiles of crime are
relevant. Management and
breeding practices may be
the decisive issue in the
potential danger of
individual dogs.
Lockwood46 argued that the
types of owners who
irresponsibly produce
problem dogs, have selected
a variety of breeds over
time. Significantly, in
London in the eighteen
months to May 1991, 30 of 50
criminal incidents involving
dogs (setting them onto
people etc.) involved pit
bulls,6 and of 20 deaths
caused by pit bulls in one
U.S. survey, half the owners
were males aged between 20
and 25, and more than half
were either involved in dog
fighting or had criminal
records.47 The United Kennel
Club, a registry for APBTs
since the 1890s, claims that
no registered APBT has ever
been involved in a
fatality.48 If so, this
indicates that the breed is
not deadly when kept by
owners who buy registered
dogs.
Conclusions
Dog attacks are a
significant public safety
issue in Australia, as
elsewhere. However, a tiny
minority of the dogs in our
communities bite people in
any given year.17 The
available data show clearly
that the American Pit Bull
Terrier is not involved in
more attacks or serious
attacks on people than other
breeds - indeed, it is well
down the lists of frequency
of attack by breed. In
America in the 1980s, the
decade of the "pit bull
panic", with an estimated
pit bull population of
500,000 - I million,49
accepting the most damning
figures, in any given year
one pit bull in 62,500 to
125,000 killed a person. The
average American person was
at least five times more
likely to murder somebody.4
The case that the APBT is an
especially dangerous dog is
not convincing. Though
American data lend some
support to this view, they
are so seriously flawed as
to be unreliable, and the
sociology of the human-dog
relationship is probably
more important than
inherited breed disposition.
In Australia the available
data show the APBT to be
less dangerous than several
other breeds in absolute
numbers of attacks on
people. There are no data
available to assess breed
attack rates relative to
breed populations, so a
definitive judgement on the
relative danger of various
breeds must be suspended.
What emerges clearly from
analysis of available data
is the fact that attacks are
committed by a small
proportion of individuals of
any breed.
