i've heard that pitbulls have a natural aggressive behavior and not too safe for the kids, based on my friend's experience..they had the dog since he was 12 weeks old,when my friend had a baby and she started walking,the baby accidentally stepped on the dogs tail,bit the baby on her face..pitbull had a locked-jaw and pulled-out a chunk of the baby's face...
so good-luck to pitbull owners..i just never liked this breed of dog.

No, please tell me who is Vick?

Any breed can be taught to be aggressive and dangerous. Pits are incredibly strong and in particular they have wide jaws that by design are prone to doing more damage than the narrower muzzles of some other breeds. Also, they are terriers and all of the terriers have a high prey drive and therefore have a predisposition towards aggression.

None of this means a pit cannot be a big sweet baby who would never hurt a child or other critter. Many people believe that dogs are made aggressive by being mistreated, which is true, but it is not the only cause. Often it is the human tendency to cater to the dog's whim and fail in their responsibility to teach the dog that some actions are simply not allowed, that creates a dog that cannot be trusted. Allowing a dog to take a dominate role in the family can lead to disaster. Children are viewed by the dominate dog as submissive and therefore the dog will consider it his responsibility to keep the child in its place. Obviously this can lead to a severely injured, or worse, child.

Excessive pampering is just another form of mistreating a dog. This does not mean a dog must be yelled at or scolded all the time, nor would I ever endorse striking a dog. My pitX is totally spoiled; he has toys everywhere, gets treats all the time, and has plenty of exercise. But he understands that aggressive behavior is not allowed. I decide if we will play tug and I decide when the game is over and he will 'drop it'. He has been taught since day one, that if I want to take food away from him, he will allow it, because I am Alpha in our pack. If the cat wanders up to his bowl, he can look at me with pitiful eyes, but he had better not threaten the cat. I will remove the cat that is my job, not his. Out of fairness, I never would allow the cat to push the limits. Allowing the dog to suffer frustration is also abusive; it is a form of teasing that will lead to aggressive behavior. When dogs have no limits, when they can do anything and behave in any way, trouble is just around the corner. It does not matter what breed the dog is, any dog can be taught that nasty behavior gets him what he wants. Just as any dog can be taught that good behavior is the only way he will get what he wants.
