Your current dogs look like good old mutts to me, cute ones at that Truthfully, they don't even look all that "Bully" to me, but more pictures would help.

Oh and, this is my AmStaff, Sako, who is AKC & UKC registered.. just for another picture reference:



And yes, you should be able to register a dog with Bully lines with the ABKC. Although I'm not an expert on that registry, so others might chime in and have a more in depth answer. I know some people who get UKC registered dogs that are blatantly AmBullies that toss the UKC papers and register them with the correct registry.
