So did mine. One time he started sight chasing one and when the other dogs fell in on it he quit and came back to me. Lol! The only two things that saved him was I knew he was out of good stock and he was a real good looking dog. Looked a lot like your dog. I started taking him out behind the house at night with my hunting light. When I saw a rabbit I would pick him and walk toward the rabbit holding his head so when the rabbit took off he would see it go. He would give a very short sight chase and come back , never barked. One night we had a fresh snow and I took him out back and when the rabbit took off he sight chased it a bit , came and started smelling where the rabbit had been setting. Then he started moving the track real slow. The more he worked it the more he snuffled and snorted. Then he yipped a couple times then barked. The further he went the faster he got and the harder he barked and he circled that rabbit. He turned out to be a pretty darn good rabbit dog. Would not run with the other dogs. Solo only. I sold him to a guy who wanted one rabbit dog for him and his son. They loved him. If I didn't live so far from you I would be tempted to take a chance on that dog.
