This B&T guy is listed as a cavalier mix -- except for the muzzle looks pretty cavalierish to me; might be a puppy farm or backyard-bred cavalier as I've seen them like this before. I see the link names him as a part cocker but doesn't say this on the notice for him so maybe that was someon'es guess. He looks lovely.

This shelter is in Maryland, if anyone US-based is interested in this older fellow.
