So i have a reservation dog which was given to us when he was 5 months old "we think". We socalized him with many different dogs and people. He is a perfect angel when it comes to people but resently we have been having issues with dogs he is not use too. We think he is now 9 months old. So the problem is i am not sure if it is aggression or dominence he is portraying. He will go up to the other dog and sniff for about a minuete then out of no where he bares his teeth and will fight the dog. He has never drawn blood and from the books i have read he is showing normal adolescent male dog behavoir. My fear is that it is not getting any better and i and my family do not like the way he is reacting since he is friendly with all of his old dog friends. We have tried not allowing him to see other dogs and training him which he sits, lays down and lets us go through the door before he does. We have even done the treats while passing other dogs. We are unsure of what to because he is a loving dog besides when after a couple minuetes with a strange dog.
Help
