Panting, drooling, trembling, sweaty paws, tense, body, shedding and dandruff, changing eyes, etc

32
Q

Define stress

A

Stress is an influence on the dog that deviates the dog from homeostasis, the normal baseline state of one particular dog. Stress can trigger a happy state or an unhappy state.

33
Q

Reactive behavior

A

When an individual has an unreasonably strong reaction to an event or stimuli . This reaction can be positive or negative

34
Q

Ambivalent Behavior

A

The dog is unsure, unclear, undecided. The body posture might show both offensive and defensive components at the same time. ( What behavior this turns into, what decision the dog comes to, is often dependent on the environment)

35
Q

What is displacement behavior?

A

Displacement behavior is normal behaviors offered or displayed out of context.

36
Q

What are calming signals?

A

Behavioral cues that produce pacifying effects on the animal exhibiting them. They can sometimes have mutually pacifying effects on others. Are often displayed to resolve a social conflict.

Q

List some examples of calming behaviors

A

Yawning, stretching the tongue, scratching, licking, turning away, blinking or averting their eyes, splitting (when one dog walks between two others that are having a tense, social interaction ), etc
