Q

What types of aggression are more of a problem in males than in females?

Dominance-related and territorial aggression.

Q

What are 3 early life experiences that can influence aggression?

A
  1. Learning
    - if during the rearing the dog learns that a growl, threat or snap results in a family member member backing off, aggression will be reinforced
    - learning can also play a role in reducing or eliminating aggression
  2. Pharmacological considerations
    - little literature to suggest drugs are useful in treating aggressive behaviour
  3. Aggression secondary to other disease processes
    - can result from brain lesions

Q

What is dominance-related aggression? Causes? Prevention?

A
  • Most common type of aggression, aggression towards the caregiver(s)
  • Often a fxn of the owner’s inability to control their dog or inconsistencies in how they interact with their dog

Causes
- natural tendency for dogs to attempt to be dominant
- breed and sex predispositions

Prevention
- follow safety guidelines
- avoid triggers
- R+ obeying commands
- if one family member has trouble with the dog, all members of the family should ignore the dog except the person having the trouble
- neuter
- desensitize triggers

Q

What is aggression towards young children? Causes? Resolution?

A
  • Usually happens toward a new baby or young child; once old enough they need to be taught how to interact with dogs
  • Relates to the way in which affection and attention shape a dog’s behaviour
  • Habituate with a doll

Causes
- dog develops dislike of baby since baby takes attention
- owners punish dog’s unfriendly behaviour toward baby
- owners give affection and treats when baby is absent
- baby becomes an aversive stimulus

Resolution
- follow safety guidelines
- withhold affection for the dog when the baby is absent
- give affection and treats only in baby’s presence
- implement social punishment if dog growls

Q

What is pain-induced aggression? Resolution?

A
  • Self-protection against pain is a natural inclination in animals; protective response when the painful area is handled
  • Some animals stoic in their behaviour despite being injured (ex. rabbits)
  • Even after an animal has been treated, they may continue to show aggression when touched or handled in the area (conditioned response)

Resolution
- follow safety guidelines

Q

What is idiopathic aggression? Breeds with genetic predisposition? Causes? Resolutions?

A

Episodic or dysfunctional rage
- implies an underlying CNS abnormality
- unpredictable and unprovoked
- may be no apparent explanation

Breeds
- English springer spaniels

Causes
- genetic or pathophysiological abnormality
- syndrome with several possible causes
- neurotransmitter disorder

Resolution
- human safety is priority
- euthanasia may need to be considered

17
Q

What are 4 types of inter-dog aggression?

A
  1. Aggression only in the owner’s presence, within identified hierarchy
    - dominance-status aggression
  2. Aggression in the absence of dominance hierarchy
    - usually in dogs of similar age and size; close in dominance
  3. Aggression towards strange dogs away from home
    - contributing factor is the degree of socialization
  4. Predatory aggression toward small dogs
    - small dogs attacked as prey
    - inadequate socialization to smaller dogs
18
Q

What is dominance-status aggression (toward other dogs)? Causes? Prevention? Resolution?

A
  • Occasional aggression toward CONSPECIFICS within the group is normal in many animal species
  • the attack on small dogs by large dogs may reflect predatory behaviour
  • within a household, dominance may be altered over time (change in members)
  • many problems arise when owners interfere with the social order

Causes
- dog group has an established hierarchy

Prevention
- socialize young dogs early in life to other dogs- very important: learn body language and how to express social position to avoid a fight

Resolution
- avoid emotional or exuberant greetings
- R+ owner control

19
Q

Anxieties and Fears

A
  • In nature, fears of strange noises and strange animals are adaptive responses
  • Anxiety or panic at the prospect of being abandoned by group members is an adaptive response bc being abandoned can be dangerous
  • Most animals are hesitant when they find themselves in a new situation; they learn to habituate; if the dog was well socialized they will be curious
20
Q

What is anxiety?

A

An emotional rxn often described as GENERAL UNEASINESS connoting a rather vague rxn

21
Q

What are fears?

A

Emotional reactions related to SPECIFIC OBJECTS, such as loud noises or children

22
Q

What are phobias?

A

Fears of objects or situations, which are cognitively understood to be WAY OUT OF PROPORTION TO THE ACTUAL DANGER

23
Q

What are the 4 causes of fear in dogs?

A
  1. Absence of prior habituation to a fear-evoking stimulus in the animal’s background, especially as a puppy
  2. Anxieties and fear rxns can be enhanced by the owner if they provide reinforcement in the form of comfort to the dog when it acts fearful
  3. Acquired through adverse experiences
  4. Reflects a physiological basis and is due to an abnormally low behavioral threshold or an abnormally intense fear rxn to fear- or anxiety-evoking situations

*clinical cases commonly involve several of these processes

24
Q

What does separation anxiety include? What marked distress is exhibited?

What type of response is SA?

A

Includes:
- digging, chewing, scratching at doors, howling, barking, crying, urination, and defecation

Marked distress exhibited:
-destruction and house soiling are not a dog’s attempt to punish or seek revenge on their owner, but are part of a PANIC RESPONSE
- may be depressed, excited, or anxious when you prepare to leave the house; might also see mixed messages

25
Q

What are 6 reasons for separation anxiety?

A
  1. Left alone for the 1st time
  2. Lack of prior habituation of absences
  3. Following a long period of being together
  4. Change in owner’s work schedule, family routine or structure
  5. After a traumatic event
  6. lavish affection prior to departure and upon return
26
Q

What are 4 aspects of treating separation anxiety?

A
  1. keep arrivals and departures low-key
    - can pair treats with departure if animal is calm
  2. leave dog with an article of clothing that smells like you
  3. desensitization techniques for severe cases
    - systematic process of getting dog used to being alone
    - teaching calm during “practice” departures and short absences
    - use R+ (counter conditioning) to reward calm response
  4. never punish
    - it is a panic response, not disobedience
27
Q

How to approach fears to an inanimate object

A

Desensitization of fear of objects or situations starting with weak stimulus

28
Q

How to approach fears to thunderstorms

A

DSCC through scheduled or staged thunderstorm training sessions
- neutralize what previously caused fear and R+ the response you would like instead

29
Q

How to approach fear to children or other ppl

A

Desensitization to fear-evoking stimulus (such as through distance gradient)
- children can be unpredictable in their movement and actions, sometimes causing pain in dogs

30
Q

What are 5 types of barking?

A
  1. Response to environmental stimuli
  2. Social facilitation
  3. Play-evoked barking
  4. Barking toward neighbour dogs
  5. Learned barking
31
Q

What is excessive barking? Causes? Resolutions?

A

One way dogs communicate is through vocalizing, it can act as a warning device or caused by social isolation, frustration, and attention-seeking or the result of territorial or protective behaviour or due to fears or phobias. It may be socially facilitated as well.

Causes
- breed predisposition
- secondary to SA
- acquired because of R+
- provoked by enviro stimuli
- social facilitation

Resolution
- eliminate or treat cause
- discontinue R+ for barking
- screen off provoking stimuli
- R+ non-barking
- remote punishment
