7 month old trying to eat other dogs.
My 7 month old German Shepard Sable male(Stanley) is extremely hyper. I take him on 2-3 mile runs about 2 times a week and he is obedient. The MAJOR issue that I have with him is that he is very aggressive with other dogs. He is very loving and playful with our 4 year old golden retriever and they get along. When they do play, the both of them are very mouthy and he is not extremely dominant over her. I took Stanley to my work last week and tried to introduce him to other dogs. He was immediately aggressive, ears up and lunging to get at those dogs. His tail wasn't tucked and I could not take him off the leash. I tried to slowly guide him to the other dogs and they started to escalate their aggresivness with barks and snarling. How(if I can) do I intiegrate him with other dogs. I know he is an aggressive breed but is it possible to make this happen?
