INTRODUCTION
Some of the members of the APBC have gathered the data used in
this report during consultations with their clients. The information
is part of the case history taken at the time of a first consultation
and used to help in the diagnosis of the specific problem, or problems,
that the animal is exhibiting.
The purpose of the review is to examine trends in behavioural problems seen by
members and to look at relationships between the presentation of certain types
of behavioural problem and other aspects of pets' lives. It is not the intention
of the authors to imply causal relationships between these factors and the problems,
since the data are necessarily anecdotal rather than the results of controlled
scientific experiment. However, anecdotal evidence is not without value, and
may highlight factors that need to be taken into account when, for example, rescued
dogs are re-homed, or a particular breed is recommended as a pet.
CASES SUBMITTED
The proportion of males and females referred with behaviour problems is remarkably
consistent in dogs. Over the past four years between 58% and 62% of canine cases
seen have been males. The difference between the sexes is statistically significant
(Mann-Whitney U, P<0.05). In cats, however, the variation is slightly greater,
with between 48% and 61% being males.
The very high number of feline cases seen that are neutered, between 98% and
100% over the past four years, is likely to reflect the proportion of domestic
pets that are neutered. The same may be true of the proportion of neutered dogs
presented, since neutering is less frequent among the canine population than
the feline.

The three most commonly referred breeds also remain consistent, with the only
variation over the past four years being the relative positions of German Shepherd
dogs and Border Collies in the list. Crossbreeds are always the most frequently
referred. It is not possible to draw inferences about whether these breeds are
more prone to behavioural problems than others, since the representation of the
breeds in the total canine population is impossible to determine. Although German
Shepherds are usually among the breeds most frequently registered with the Kennel
Club, Border Collies and working sheep dogs are often unregistered or registered
under the working and obedience register, while crossbreeds are, by definition,
unregistered.
For feline breeds the same problems arise, although it is likely that the domestic
short hair is more commonly represented in the population than any breed.

CANINE CASES
The canine behaviour problems that were referred to some members of the APBC
(and their associates) during the year 2001 are shown in Figure 1. The most common
behaviour problem referred was aggression towards people (36%). This category
included status-related aggression, fear aggression, possessiveness over the
owner, food aggression and play biting.

Key To Figure 1
AP Aggression towards people. Possible causes include fear or status.
AD Aggression towards dogs. Possible causes include fear or rank.
SP Separation problems - occur when separated from the owners.
F Fearful and phobic behaviour to auditory or visual stimuli.
AS Attention seeking behaviours e.g. barking when owner uses telephone.
T Training problems e.g. poor recall
Ch Inappropriate chase behaviour e.g. towards vehicles or joggers.
Misc Miscellaneous behaviour problems e.g. escapology and copraphagia
HT House training problems.

Other Other behaviour problems not classified.
RB Repetitive behaviours e.g. tail chasing
Aggression towards other dogs was referred in 19% of cases. This category included
fear aggression, chase motivated aggression, learned/frustrated play and aggression
between same sex/opposite sex dogs in the family.
After aggression, separation problems and fearful and phobic behaviour towards
auditory or visual stimuli were most frequently referred (9%). The most usual
motivation for separation problems was anxiety, which may be due to an over-attachment
to a member of the family. Symptoms of separation anxiety include destructive
behaviour, vocalising and toileting. Other motivations in separation problems
include attention-seeking, which may be a continuation of behaviour learned in
the owner's presence and can include destructive behaviour and vocalisation,
fear of being alone or of sounds heard while alone.
Aggression Problems
A more detailed analysis of the aggression problems referred in dogs during 2001
shows that fear aggression towards people was most frequently presented (25.5%),
followed by aggression towards dogs (12%), and status-related aggression towards
people (6.5%).
Key To Figure 2
FAP Fear Aggression towards people
FAD Fear Aggression to dogs
SA Status-related aggression to people
For aggression towards people (see Figure 3), 30% of the cases referred displayed
fear aggression towards people outside the home; 18.5% displayed status-related
aggression towards their owners; 18% showed fear aggression towards people in
the home; 17% displayed territorial aggression within the home/garden; 6.5% displayed
fear aggression towards family members; 4% carried out play biting; 3.5% guarded
food and 2.5% were possessive over their owners.

Figure 4 shows aggression towards other dogs, in which 63.5% of the cases referred
displayed fear aggression; 20% showed aggression towards dogs of the same sex
in the family; 8.5% of the aggression shown was learned/frustrated play; 5% showed
aggression towards dogs of the opposite sex in the family and 3% of cases were
chase motivated.

Fear aggression when a dog encounters people or other dogs can occur for two
reasons. Firstly, fear aggression may be shown if a dog is unused to people or
other dogs. This problem often arises through a lack of socialisation during
the sensitive period of puppy-hood, between three and twelve to fourteen weeks
of age. Secondly, a dog will often display fear aggression if it has previously
had an unpleasant experience with people or other dogs.
Behaviour counsellors are often asked if having another dog will help a dog with
behaviour problems and it may intuitively seem that having a canine companion
would help to prevent a dog from becoming aggressive to other dogs. However,
the data displayed in Figure 5 suggest that the opposite is true. A dog that
has a canine companion during its first year of life is more likely to have been
referred for aggression to other dogs away from home than one referred that was
raised without a companion. This may be because it has not learned to approach
other dogs without the support of a companion. In some cases the dog may learn
to be aggressive because the dog it lives with is aggressive to other dogs.

Key to Figure 5
FD Fear aggression towards dogs
F/L Frustrated play or learned aggression towards dogs
Dogs with a canine companion during their juvenile period also had a slightly
greater chance of being referred for frustrated play behaviour manifested as
aggression towards other dogs. This may be because they expect other dogs to
play with them in the same way as their early companion. This is thought to be
particularly likely to occur if the dog they have lived with has not inhibited
the physical strength they use in play and incompatibility between their expectation
and how other dogs behave causes frustration. These figures support the argument
for ensuring that puppies raised with another dog in the first year of life benefit
from opportunities to socialise with other puppies at puppy socialisation classes
and experience the world without their companion some of the time.
Six percent of dogs that grew up with a canine companion were referred for status
related problems towards their owners. This compares with fifteen percent of
dogs raised without a companion referred for the same reason. This may indicate
that the presence of a canine companion during the juvenile period helps a dog
to have a better understanding of the hierarchical structure of the family. An
alternative explanation could be that owners of multiple dogs are more likely
to give appropriate signals to the dogs so that they do not become confused about
their status.
Separation Problems
For separation problems, the motivation was anxiety (over-attachment) in 65%
of the cases referred; boredom (14%), fear (12%) and attention-seeking (9%).

Table 3
The percentage of dogs and bitches that were neutered can be seen in table three.
An unexpected variance of these ratios in the reporting of a problem might
indicate hormone influence or the effect of neutering. This is dependent upon
whether if entire or neutered animals are presented more frequently than expected.

Figure 7 shows that entire males were referred disproportionately for aggression
towards dogs of the same sex within the home, which might be expected intuitively.
Figures 7 & 8 show that there was a disproportionate number of entire males
and females referred for fear aggression towards people inside the home and a
disproportionate number of entire females were referred for fear aggression towards
people outside the home.

Domestic and Kennel
Most of the dogs referred that were obtained from domestic or kennel environments
were puppies. The environment in which dogs are kept during the first weeks of
life can affect the potential for fearful behaviour in later life. Dogs that
had been obtained from a domestic environment were less likely to have been referred
for territorial aggression due to fear than status related problems, the opposite
to the trend was found in dogs obtained from kennel environments.
Rescue
Most referred dogs obtained from rescue societies were acquired at an older age*
and had lived in at least one previous home. These dogs were more likely to be
referred for territorial aggression due to fear than status related aggression.
Twenty-eight percent of dogs obtained from rescue societies were referred for
aggression to other dogs away from home, which contrasts with twenty-one percent
of dogs obtained from domestic environments and nineteen percent of dogs obtained
from kennels.
*Age dogs were obtained: 87% of dogs and 90% of bitches obtained from
a domestic environment and 75% of dogs and 77% of bitches obtained from
a kennel environment were under seven months old. Only 16% of dogs and
29% of bitches obtained from rescue societies were under seven months
old.
SUMMARY OF CANINE CASES
-
Significantly more males than females were
referred with behaviour problems.
-
The two most frequently referred behaviour
problems during 2001 were fear aggression towards people
and fear aggression towards dogs.
-
The most common breeds referred during 2001
seem to be in keeping with the trends in the general population.
-
Dogs that had a canine companion during the
first year of life were referred more often for fear aggression
or frustrated play behaviour towards dogs away from home
than those that did have not have a companion.
-
Dogs that had a canine companion in the first
year of life were less likely to be referred for status problems
involving their owners than those raised without a companion.
-
Entire males were more likely to be referred
for status related problems towards other males within the
home than expected from the proportion of entire males in
the whole population. Similarly, both entire males and females
were referred more frequently than expected for fear aggression
towards people within the home and entire females were referred
more frequently than expected for fear aggression towards
people away from home.
Dogs obtained from kennel environments and rescue
societies were referred more often for territorial aggression
due to fear than status related problems. For dogs obtained from
domestic environments the reverse is true.
FELINE CASES
Figure 9 shows the feline behaviour problems that were referred to some members
of the APBC during the year 2001. The most common behaviour problem referred
was indoor marking (25.5%). This category included spraying, middening and scratching.
House training problems were observed in 25% of the cases referred. This category
included breakdowns of appropriate toileting and failure to establish appropriate
toileting. Aggression towards cats was observed in 18% of the cases referred.
This category included territorial aggression, redirected aggression and social
aggression within the home. Aggression towards people was observed in 15.5% of
cases referred. This category included redirected aggression, predatory aggression,
fear aggression, aggression during handling, learned aggression and idiopathic
aggression.

For aggression towards people, 26.5% of the cases referred displayed learned
aggression or biting during handling; 18.5% displayed predatory aggression; 14.5%
displayed fear aggression towards people inside or outside the home and 6% of
the cats referred displayed redirected aggression or fear aggression towards
the family.

O Other
Aggressive behaviour exhibited between cats living in the same household, can
be motivated for a variety of reasons, such as, defence of resources, fear or
territorial behaviour to newly introduced cats or cats that return home with
a new smell on their coats and are not recognised, redirected aggression and
learned behaviour.
Key To Figure 12
TA Territorial aggression
RA Redirected Aggression
SA Social aggression within the home
87.5% of the cases referred displayed social aggression within the home; 9% displayed
territorial aggression and 3.5% displayed redirected aggression.
Indoor Marking
Indoor marking can take the form of spraying, scratching and middening. Spraying
occurs when a cat deposits a small amount of urine, usually on a vertical surface.
In the predominantly neutered pet population this behaviour is most commonly
used to increase the sense of security felt by the cat. Middening, the deposition
of faeces in a prominent position, is more often used to mark the cat's walkways
away from the core area of its environment.

Key To Figure 13
SP Spraying
M Middening
S Scratching
For indoor marking, 94% of the cases referred sprayed; 5% displayed scratching
behaviour and 1% carried out middening behaviour.
SUMMARY OF FELINE CASES
-
The behaviour problems most frequently referred
during 2001 were social aggression towards other cats within
the home, inappropriate toileting and spraying.
-
There was no difference between the number
of males and females referred.
-
The most common breeds referred during 2001
were domestic short hairs, burmese and persian cats.
-
Cats referred for aggression towards people
most frequently showed learned aggression or aggressive during
handling.
-
Cats referred for aggression towards cats were
most likely to have shown social aggression to other cats
in the home.
-
Spraying was the most frequently referred form
of indoor marking behaviour.
