Aggression

Before instituting any training program, see your veterinarian. In many cases, the underlying reason for aggression is pain or discomfort. Rule this out first, not last. Next determine cause, then act accordingly. This chapter is designed to give you insight only. For any serious biting or aggression, seek out a qualified trainer that uses positive reinforcement techniques. Over dominant approaches can have a reverse effect over time. Above all, understand the underlying reasons for the behavior and then use your common sense.

** Very dangerous situation. Do not attempt to do this one alone, seek professional help! Keep in mind that not all dogs can be re-trained to live within a family situation.

Not all biting is true aggression, some is exhuberance or instinctual. It is essential that you know ‘why’ your dog is biting. Not all biting dogs are treated the same. Once you understand you dog’s motivation, the re-training will be more effective and safe.

A professional trainer with behavior experience can give you the best insight on the reasons why. They should meet the dog and see the behavior in order to make a correct assessment on his motivation and give you the appropriate advice.
