I hate to hear that about Munnu. Aggression is a very complex problem and one that may be difficult to fix without a trainer. Aggression can be related to dominance, possessive behavior, fear or anxiety and each one needs to be addressed in a different fashion. The trainer will be able to determine the cause. The trainer will then work with you and your pet to modify both of your behaviors to meet a common goal. There are several different training methods so you will need to find the one that works best for you and your pup. You should also pick up a few books about dog behavior and dog training so that you can learn to recognize your pet’s body language. By knowing what he is saying, you be better able to react before he reacts. I hope this at least points you in the right direction. Please post again with any further questions.
