Help please. I have adopted a great little rescue dog named Handsome. He is perfect except that he goes crazy when he sees certain dogs and gets agressive, growling and snarling at them. They are usually bigger dogs. Some dogs including my other dog he gets along great with. We live in a high rise with alot of dogs in the building so we are always coming across the other dogs and nothing is worse than being in an elevator with my lovely dog turned Cujo.
What on earth is going on with my dog?? He is neutered, about 1 yr old, 12 pounds, perfectly housebroken great dog except for the Cujo part.
Help please..Is it because he thinks he is protecting me and my other dog (teacup chihuahua)
