So. I have an 8 year old Welsh Corgi male dog named Charley that does not like any other dog. He growls and barks and tries to get away from me to attack the dog. I know he will do damage because there was this other dog that wasn't on a leash and came up to Charley to sniff him, but Charley tried to bite the other dogs neck! So my question is how can I get Charley to at least accept other dogs? Is it even possible? Thanks.
