All dogs bite. It just depends on the circumstances. ETA: I read some of the other posts, and wanted to add something. I've been around the breed since my single digits. I've taken bites from APBT, a Dogo, a Rottweiler. I've never seen a dog clamp down with the intent to do damage. All of the dog-to-human bites I've seen were a single bite just like any other breed would do. A dog biting down on a human and engaging in an extended attack is rare.
