Hi guys, first post on this forum from me. I’m new to owning sight hounds and wanted an idea of what cross you guys think my boy is? He’s 5 months old rescue. Never seen the parents. My thought is collie / grey, but would appreciate your advice. Also if you have any training advice regarding other dogs that would be great, he keeps biting other dogs on first interaction which then causes other dogs to be wary of him and I think makes him more nervous and he tends to try to nip again. I’m aware that this is quite normal for dogs his age so just wanted to know if anyone had anything similar happ
