Is that purple on the tongue? Isn't that something that a purebred would have? Midnite and Brennan both have it. I don't think I've ever seen that on a mix breed, maybe a chow mix, but I personally have only seen it with purebreds.
Not sure, I haven't seen him in person yet... He is in one of our foster homes. My wl boys had those black/purple marks on the tongue.
