My Aussie is a perfect dog 99% of the time. However, there is a dog in the neighborhood he hates (for lack of a better word). This dog has done nothing to mine. For a couple of years my dog just gets very aggressive with this other dog. Can anyone help me train this out of him or am I just bound not tho let the two dogs meet.
PS My dog was a rescue , he was 4yrs when I adopted him. So, not sure of his background before I got him.
