Ok, you have all made some good points. My Dad bred sled dogs, so I have some knowledge. First- no breed is instincively vicious. All CAN be trained to be vicious. It is much easier with some breeds than others, tho. Pit Bulls have such a bad rep- as they are FAR too often bought & trained to be vicious- and, of course, they are one of the easier breeds to make that way (altho many of the small breeds are actually nastier, no-one really gets very “mauled” by a chihuahua). Also note, all dogs have some odd things which “set them off”, which are unpredictable. I had a Shetland Sheepdog- fine, UNLESS you made a grab for “HER bone”- when she was under the kitchen table. Just bones, just the table.
However, Pit Bulls do deliver a VERY nasty bite. AND, when that “odd thing that sets them off” does happen- they just attack- not like my Sheep Dog who would snarl & snap, first. Ie, you might not know that picking up a bone under the table would cause her to 'go off on you"- but when she did 'go off"- she would warn you 1st. It would take a REAL idiot to keep trying to take that bone after a dog “snarls & snaps”. But Pit bulls don’t do that- they just attack.
So- clearly there is something “wrong” with Pit Bulls. However, they can also be very sweet, loving animals. But does that mean that breed should be banned? No- that means we need to put them ONLY in the hands of responsible owners, and make sure folks can buy them (actually the AKC version, which is not quite the same thing) ONLY from reputable breeders. I hope that reputable AKC dog breeders will not sell their puppies who want “killer dogs”- and in any case, they would be expensive.
Thus, I am in favor of licensing dog breeders, with particular care taken to those who breed pit bulls, rottwielers, wolf-crosses, etc.* It would be illegal to sell, or offer to sell a dog without being licensed. After a while, you would have to show that your dog, especially from a “potentially dangerous breed” came from a licensed breeder. (Say, 5 years after, any dogs a year old or younger, etc). Next, no person could own more than 1 dog that was not neutered unless he had a license.
- ie, if someone is breeding Chihuahuas, they just pay the (small)fee, and show they have proper facilities. “Potentially dangerous breeds” might get a brief background check, and a couple of visits.
