I had a half pit half jack squirrel dog for years. Best dog I ever had. He was about 40lbs of electric muscle. Would kill any vermin in sight, sound, or smell. Killed cats, coyotes..yes coyotes, coons, possums, armadillos, and fighting roosters(my buddies) - was also a great squirrel dog. Used to take him to our hunting camp and drop the tailgate. We had a feral cat problem. The fighting and killing was epic. Damn I miss that dog.
