 Because what happens now when he sees a little dog and he starts becoming aggressive towards the dog, you're saying, no, no, no, and you're pulling him back, I'm assuming. Therefore, you're actually creating more, more anxiety, more aggressive, more assertiveness on his part. So I would do some solid training at this point. I don't care how old the dog is. They can be trained at 20 years old as far as I'm concerned.
