I always wonder why pit bull attacks are so common these days. They are really sweet dogs. Their love for human is just unparalleled . Every dog has a special work to perform and dogs are designed to do that work. Pit bulls were created for fighting other dogs and to be loyal to their masters (humans). It seems the recent attacks on the humans by the pit bulls are result manipulation of pit bull breeds on various levels including breeding , training and feeding. A true specimen of these breeds should never be aggressive towards human. Aggressive behavior towards other animals,especially towards other dogs , could be justified by giving the reason of their fighting background but aggressive behavior towards the humans is a fault in the pit bull breeds and it should not be encouraged by the breeders.
