Aggressive behaviors refer to a variety of different things a dog does, and different emotional states a dog might be in. Offensive aggression is characterised by some or more of the following:
- Moving toward the target
- Showing teeth
- Raised hackles
- Barking and growling
- Tail raised, possibly wagging
- Ears erect and forward
The dog’s primary emotional state is one of anger rather than fear; he wants the target to go away, but not because he is afraid of it. One example of offensive aggression is territorial aggression.
