I agree there, too, about the extreme looking dogs...like english bulldogs, they will end up with a lot of health problems. The American bully is super variable in its standards, party due the different classes, some look very similar to AmStaffs, others are practically bulldogs, with some being as tall as a beagle and others nearly the size of a mastiff, and many in between. See second photo below of an "exotic" bully next to a classic American bully- both are called American Bullies by their breeders and owners, but they're rather different.The American Bully is recognized by the UKC, as well as some other organizations. A Classic Am Bully looks rather like a very heavy-set APBT or Am Staff, and are pretty nice looking dogs, IMO. However, the Exotic and Extreme type dogs.... well, suffice to say that I, and lot of others, don't care for them.
