I was curious about this and looked at the pictures too and it just looks like a run of the mill mixed-breed dog to me. I've worked in a shelter and have seem some pretty strange mixes in my day, so this didn't seem odd to me at all. There are a lot of snub-nosed breeds of dogs, and mixed with something like a chow or some other equally thick-furred breed of dog could very well make a mix like this. Poor thing.

If it was such a mystery, these people should have been a little more quick on the up-take and made an effort to collect the body and examine it.

RIP beastie.

Remember good ol' Sam?

This face is pretty frightening, and he may not have looked like a typical dog, but he was...same thing with beastie.
