Different dogs have different tempermants. People purchase pure breeds because of certain traits they have. Why we have herding dogs, hunting dogs, dogs for protective, dogs to sniff out drugs. Everyone knows that labs make good family pets and are wonderful with kids. I believe that Pit Bulls are not a family dog, their tempermant is not suited for this role. Are there kind, gentle Pit bulls, yes but not as many as labs. We except the fact that a German Shepard is a good watch dog. A bloodhound is excellent for tracking a Newfoundland for swimming how about excepting a Pit bull for having a bad temper and the ability to kick some butt. That is what they are bred for and they are for the most part true to their nature as are Bloodhounds. Breeding shows ,breeding often overcomes training.
