wow I am amazed at the photo of your dog, because now I think I know what the heck type of dog I have. She is a shelter dog, and still a mix, but she has a few very unusual features. Most prominent is her coloring, and a nose/muzzle like I’ve never seen. The only difference is her ears flop when not perked for listening. They had her billed as a “chow mix” but I don’t wonder if it is because her tongue is mostly black.
