We rescued a 5wk old puppy about 12yrs ago, told he was a lab x gsd he turned out to be a rottie x gsd and he turned out to be a nightmare a very aggressive, territorial dog, he became a serious liability and it was our fault,our first puppy we had ever owned so not enough experience for this type of breed, very young children so treat as a lovely cuddly puppie toy not enough firm handling, inexperienced so missed the signs of early aggression.

This was a dog in the wrong hands. I know its different from the idiots in the article but what ime trying to say is i dont believe any dog is born bad its how they are brought up.
