FEARS,
PHOBIAS AND ANXIETIES What is fear? Fear
is a physiological, behavioural and emotional reaction to stimuli that an animal
encounters. The physiological
reaction results in an increase in heart rate, increased respiratory rate
(panting), sweating, trembling, pacing and possibly urination and defecation.
Behaviourally an animal will exhibit changes in body posture and activity
when afraid. The animal may engage
in an avoidance response such as fleeing or hiding.
It may assume body postures that are protective such as lowering of the
body and head, placing the ears closer to the head, widening eyes, and tucking
in the tail under the body. If the
animal perceives a threat, the response can also include elements of defensive
aggression. Whether an animal
fights or flees when fearful or defensive depends on its genetic predisposition
and the environment that it is in (see below).
The emotional reaction in animals can be difficult to gauge because
animals are non-verbal. However, by
observation of body postures and facial expressions it is possible to conclude
whether or not an animal is afraid. Is fear a normal or
abnormal response in animals? In
many situations it is "acceptable, understandable and perfectly
normal" for an animal to be afraid. However,
there are times when animals exhibit fear which is maladaptive or dangerous for
humans. When animals are frightened
they may become aggressive (fight), run away (flight), stay still (freeze), or
display appeasement behaviours. Which response a pet exhibits depends on the pet's
personality and emotional development, the type of stimulus, previous experience
with the stimulus, whether it is on its own property (where it is more likely to
fight), whether it is in the presence of offspring or family members (where it
is more likely to fight), or whether it is cornered or restrained and unable to
escape (where it is more likely to fight). What is a phobia? This
is an intense response to a situation that the animal perceives as
fear-inducing. The response is out
of proportion to the stimulus and is maladaptive.
Phobias relate to a specific stimulus or group of stimuli and common
examples are phobias involving
noises and places. Phobic responses consist of physiological, behavioural and
emotional responses similar to fear, but they are extremely exaggerated.
The response does not attenuate with time. What is anxiety? The
human definition of anxiety is a diffuse feeling of impending danger or threat.
It appears that animals can exhibit this diffuse type of anxiety, often
manifested as generalised anxious behaviour in either specific situations (the
veterinary hospital or unfamiliar locations) or in a non-specific way (in
response to alterations in the normal routine or environment).
Anxiety is manifested by some of the same physiological signs as fear,
but also may be displayed as displacement or redirected behaviours, destructive
behaviours, or excessive vocalisation. Any
of these behavioural responses may become stereotypic or compulsive over time.
What types of
stimuli might trigger fears, phobias or anxieties? The
triggers for these behaviours are many and varied. Animals may be frightened of people, other animals, places or
things. They may show an anxious response in non-specific situations or a phobic
response in one particular situation such as toward a thunderstorm. What causes fearful, phobic or anxious responses? Sometimes
fear is the result of an early experience that was unpleasant or perceived by
the animal as unpleasant. If the
fearful response was successful at chasing away the stimulus, or if the pet
escaped from the stimulus as a result of its response, the animal's behaviour is
rewarded. Owners that try to calm
their pet by providing treats or affection may be rewarding the fearful
behaviour. It should be noted that
punishment, in close association with exposure to a stimulus may further
increase fear and anxiety toward that stimulus. It
is not only unpleasant experiences that can result in the development of
maladaptive fearful responses. Any stimuli (people, places, sights, sounds, etc.) that a dog
or cat has not been exposed to during its sensitive period of development, which
is up to 12 to 14 weeks in dogs and 7 weeks in cats, may become a fear provoking
stimulus. For example, the dog or
cat that is exposed to adults, but not children during development may become
fearful when first exposed to the sights, sounds or smells of young children.
The pet's genetic make-up also contribute to its potential to develop
fears and phobias. Phobic
responses can occur as the result of just one exposure to a particularly intense
stimulus or they can gradually increase over time as the result of continued
exposure. In cases of pathological
anxiety and fear, neurotransmitter (brain chemical) function and levels may be
altered and contribute to the overall behaviour.
The consequences that follow the phobic response (rewards, escape,
punishment) and the learning that takes place as a result may also aggravate the
response. Is it
possible to prevent fears, phobias and anxieties? A
good programme of socialisation and exposure to many new and novel things while
an animal is young is essential to facilitate normal emotional development and
thereby help in the prevention of fears and phobias. However, in the phenomenon of "one trial" learning,
an event is so traumatic that only one exposure can create fears, phobias or
anxieties. Owner
responses when their pet experiences a new situation that could potentially be
frightening are important. Happy
cheerful tones, and relaxed body postures of owners can help pets to experience
new things without displaying fear. Calm
reassurances may also be beneficial provided that the pet is not acting in a
fearful manner at the time of interaction.
Knowing your pet and its individual temperament will also determine what
situations you can and should expose your pet to. Each
time your pet is exposed to an anxiety, fear or phobia inducing situation and
experiences a non-adaptive response, the problem is likely to worsen.
Finding a way to control, relax, or distract your pet in the presence of
the stimulus is necessary to correct the problem and to teach your pet that
there is nothing to be feared. An
owner who is calm and in control reduces the fear and anxiety associated with
new stimuli and situations. For
most cases of fear, appropriate behaviour modification techniques involve
exposing the pet to mild levels of the stimuli and rewarding it for non-fearful
behaviour. Consequences that
reinforce the fear (inadvertent rewards or retreat of the stimulus) or aggravate
the fear (punishment) must be identified and removed.
Drug therapy may be a useful adjunct to behaviour therapy techniques when
dealing with anxiety, fears and phobias and where the responses are pathological
pharmacological intervention may be necessary. |
