We got a 18 month male the other nite, it is the most laid back dog I have ever seen. It has 0 drive no toy drive at all. It will not play or run any. We took it to the vet for a check up its healthy but it lays around and does nothing. It doesnt have food drive either it will sit and down for treats but not motivation doing it. The only thing it throws its ears up and pulls towards is our 7 year Yorkie it looks like it wants to play with her but not 100% sure. We don't let him off lease around her yet. Any ideas what to do ?
