I adopted a 4-year-old Sheltie, a breeding male who has thrown blue merle pups. My groomer looked at him and said, "he's a Sable." Then after grooming him, she said, "You know, maybe he's a merle. The shading sure looks like it." So here are some pics. He's very hard to photograph if he's paying attention to me. The only way I can get a decent photo is to either surprise him or take one when he's not looking. Please tell me what you think. https://www.flickr.com/photos/[email protected]/ ""
