A good book to read is "The Dog's Mind, Understanding your Dog's Behavior by Fogle, DVM - Can not find my copy.
Dominance Aggression - This is when the dog's status in the pack is challenged. Maybe by a new dog coming into the house. A puppy that growls when another trys to take a toy. Even eye to eye contact will bring out the aggression among two dogs or a dog and a person. Some think this is why children sometimes are attacked by some breeds of dogs.
Even puppies it is shown - when a puppy mounts another puppy. Trying his best to show a little dominance.
Fear aggressive - if a dog is cornered out of fear they become aggressive.
Protective aggressive - This dog defends his "stuff", his territory. His yard, his toys, his food his master, his favorite chair.
Forget what another is....but is when dogs have the preditory instinct to herd sheep...and act in a preditory manner.
It is preditory aggressive I believe.
A good book on understanding dog behavior and why they act the way they do is a good investment and often you can get used books. |
