They're both cute. Thank you for rescuing them. Blues do tend to have thinner coats sometimes. My blue fawn has no fur from his chin to his tail underneath and just fuzz on his head. My blue and tan just has fuzz on his head, but fur all over him. The fuzz feels like velvet. They are definately mixed with something, at their age, their ears wont pop up. And their head shape is deer shape. Clyde looks more chi while Bonnie looks like she has some hound or pit bull in her. But both are beautiful and once you get them de-flead and socialized, they will make you some wonderful pets. Best of luck.
