Hey, guys, common things are common! It's a DAWG!!!! Hair too long for coyote or coon, long fluffy tail without rings, no mask, elongated snout, paws not hands. The dark markings on muzzle and legs look like a Shepherd mix. And that wound in the neck looks interesting. If it was rabid, it could die twisted and writhing with lips pulled back. I'd ask about rabies in the area, missing dogs, known feral dogs, etc. I think the hole in the neck is from predation, not sure. Awesome thread!!!!
