| Hi,
I may be "way off base" here, but it does sound like your dog is being "intimated" by the other dog he visits. I know you said they "have a great time together", but something is changing your dog's attitude and personality.
Usually, when a dog cowers on the floor, he feels he does not have the respect of someone or something, and is afraid.
As I mentioned, this is only a good educated guess. I am not a Vet. Maybe you could leave him at home the next time you go, and see if his "usual" self starts coming back. I do wish you and he the very best. |
