Yes, I agree, Bobby. My big Akita used to chase down small deer in our woods and chow down. Not sure how he and our other dog
caught them, but we'd find the legs.
Thanks everyone, that seems to be the consensus that it's a dog, it just looks pretty big to be a stray. I was near a farm so perhaps it's a well fed farm animal that had the opportunity to investigate some road kill? Just was not expecting that.
