Thats a canine of some sort for sure. Whether wild dog or wolf dog hybrid, doesn't matter. I have seen a couple of coy dogs in the past, last fall out past Springdale, a pair walked across the road, stood there like pets looking at us in an open hunting season, strange color patterns. Face was a coyote, but the rest of it looked like german shepherd and one even had white patches, tail like a coyote too. Their behavior was the only thing that saved his life.
