Dogs are normally possessive, but some can be more possessive than others and won’t hesitate to exhibit aggressive behavior if they feel someone is out to get what they think is theirs. A dog can become possessive of their toy, food, bed, territory, and even their humans. Dogs with possessive aggression may growl if someone goes near him while he is eating or chewing a favorite toy. He may also charge and bite an unfamiliar person who steps inside your yard or home.
Some dogs display aggressive behavior to establish dominance. Aggression is usually aimed at other dogs, but it can also be directed towards humans as well. Dogs that show this type of aggressive behavior feel that they are dominant and in charge of the situation. Displays of aggression can occur when the dog feels his dominance is being challenged.
Since a health issue can also be a potential cause of your pet’s behavior, it’s important to have your pet checked out by your vet to rule out a health issue. For more information visit to your veterinary clinic.
