When I first saw this topic, I thought the doubt about coydogs existing would be bannished quickly, so I didn't post anything. I don't have any pictures or real proof, other than what I saw. My wife's cousin in South Dakota had a dog at one time that looked half collie and half coyote. This was a pretty freaky dog -- imagine a half-way tame coyote, and that's exactly what it acted like. Very skiddish and acted like it didn't trust anyone, but would come to the fence now and then if you called for it. It also had the yellow eyes of a coyote, but obviously had dog in the blood, too. Well, this dog never became "pet-like" enough for my "cousin-in-law", and I believe it snapped at him a couple of times, so he ended up shooting it. I have NO doubt in my mind that it was a dog-coyote cross.
