There's not a lot of abnormal behaviour for dogs. Dogs act in ways that we don't accept as humans. A lot of times it's normal for the dog but it's not okay for us. However, if you're talking about seriously abnormal behaviour in dogs, we would be talking about things such as seriously excessive barking, excessive fear, and excessive aggression. These are abnormal if they get to the point where the dog simply can't function in society.
