My wife and I are looking into this breeder- Dog Days Kennel • American Pit Bull Terriers -Do any of you have experience or advice to give about this kennel? His mission is to breed a less dog aggressive Pitbull. He supposedly has a program he calls"Zero Aggression" where he breeds only dogs with little or no game. Can he possibly undo dog aggressive tendencies in his stock within a few generations? We own another dog so this is a subject we are concerned about. He claims most of his customers have multiple dogs and that he has never had a complaint from any clients regarding dog aggression. Again, any comments would be appreciated.
