Before we get started, I'll admit that a pit in the wrong hands can kill a person. I'll admit that a pit has a stronger bite than a small breed. I'll admit that most people don't know how to handle a pit... But my point here is, do most people know how to handle ANY dog that big? I've done research on dog breeds myself, and have come to find out that it's not the Pit that has the strongest bite out there. A Rottweiler has a stronger bite than a pit (I learned this while trying to help a neighbor with their unruly Rottie pup, doing research to give them a bit of insight on the breed because they refused to train her). Now, let's look at why pits are so hard to control. Firstly, they're terriers. They're bred for that single-mindedness that makes terriers, of all kinds, hard to handle. They see something and, by golly, they want to do what they want to do. Second of all, they're a larger terrier. I won't say they're 'big' dogs because they're surprisingly not "Large Breed" but instead are considered medium, because most don't even size up to a German Shepherd (which, coincidentally, is also considered a medium breed). But that still means they're a little more to handle than your standard Jack Russell. Thirdly... or, should I say firstly again, they're a terrier! They need extensive amounts of exercise in order to meet their physical needs. It's like getting a hyperactive kid and telling it to sit in a chair in a room indefinitely. You're going to have problems. Now, this isn't to say they can't be dangerous. By all means, they can! Just like any other breed of dog! Personally, I've been attacked by more unruly labs than anything else. Thankfully, I know how to handle situations like that, due to my being a certified dog trainer. My own mother had to have her face and arm stitched up from a vicious chihuahua attack, where the owner was claiming the dog was just trying to play with her. Yes, a pit can do more damage... but so can a horse. A horse can kill you with one swift hoof to the head. But we still think of them as gentle creatures. Some people will say the difference is in the head. That a pit is vicious, and will try and kill you the first chance it gets... but that can't be further from the truth. Pits are very loyal, loving dogs. Even in the fighting rings, a dog who bites a person, is gotten rid of. As a dog trainer, I have to point out that there is a difference between animal aggression and human aggression, and Pits are bred to be animal aggressive, not human aggressive. The instinct to attack another animal is something that ALL terriers have. Only difference is the size, here. Which makes it even more important that the dog, like every other dog, be trained properly. Am I saying this is a dog for everyone? No. Am I saying that pits cannot hurt people? No. What I am saying is, that like every other dog breed, this dog has needs. Needs that have to be met, or else you end up with a crazed, oversized terrier who's never been told what is and is not acceptable. What I am saying is that, with the proper treatment, like any other dog breed, this breed will be a great pet. Remember - Pits were considered a family dog for a long, long time, despite their past as bull-baiting and bear-baiting dogs. And they didn't turn and suddenly kill anyone back then, because they were properly handled. What makes it any different -now- besides the fact that they're the new face of dog fighting? Edited: As a note, I also would not recommend any dog be left out in a home while people aren't there. It's dangerous for not just other animals in the house, but for the dogs themselves, especially if you have more than one dog. Dogs who have been living together for a long time have turned on each other and even killed each other while people aren't home, leaving no explanation for the humans who have to come home to injured or dead four-legged family members. This is why I also support crate training for -all- dogs.
