Absolutely. Any dog, any breed, any temperment will bite in the wrong circumstances. There are just different thresholds. IMO, a large part of the point of early socialization is make that threshold as high as possible.

Most dogs will give you a sign that they are getting close to their personal breaking point. If you ignore that sign, the odds of a bite go up. I personally believe that most dogs don't want to bite. That biting is their absolute last resort and that they give us plenty of chances to avoid getting bit. However, a dog that truly wants to bite--will and there is little chance to avoid it. They are amazingly fast at that point.

Like Orangutango, I believe that some dogs are born messed up or end up so bad off that they can't be fixed. I think it's pretty rare. Maybe it's bad breeding--a trait picked up from the mom, maybe the female didn't get something she needed during pregnancy or maybe the dog was just miswired genetically, maybe they missed some vital socialization or just can't overcome their pasts, but something is wrong that can't be fixed.
