I owned some off of white cat Hellums and they were deer machines, and no matter how long or far they would go they would be back every night, hunting machines that would find game , I bred them to beagles, then to my beagle/gsp and they have speed, nose hunt and are good for small tracks,the gsp makes them easy to handle, average height is 20”, they have chop and squealing mouth’s. This formula works well for me.
