The bites are pretty much the same across the board. The better ones give a full mouth bite but there are a lot of shephards that are hectic and shake and grip with the front canines too.

Like most everything it comes down to the individual dog, the bite game, like the dog game, there is not a lot of 'cookie cutter' consistency.

The few pitbulls I have seen were more petbulls but pitbulls the same, if that makes sense.

Maybe the best game dog owner/protection work guy I have met had dogs bred down from Hyde's Scratch/Miss Pool Hall Red/Snooty. In the early 2000's he had pedigrees I would drool over but those dogs came from game ass parents but they did high level protection work. But training was incredibly difficult as the owner would say his dogs got amped up when other dogs were working so getting them to focus and get back on track was one of the harder obstacles to clear. He also said other dogs had that issue too, but not to the level of his bull dogs, and not to the length of lack of focus.

It can be done. But with anything the level of difficulty will change from breed to breed but especially from dog to dog.

I am on the thought train that if it is there it is there and can't be covered or hidden but only managed. Sort of like a cur, with slick handling, a lot of mouth and great conditioning the cur in a dog can be hidden, sometimes forever. But a dog that has a hundred or so years of fighting dogs in his lineage, training will do nothing more than hide or cover or better said, manage the aggression issues.

And a lot like Murphy's law the aggression will come out at the most inopportune time.

With that bit of negativity being said, I am the biggest fan of dogs doing what they were bred to do or what they were trained to do.
