check out the rescues , some are fairly affordable and youd be saving a life.
I wouldnt recommend going to a backyard breeder . minus the rescue , you pretty much get what you pay for .. as long as you do your research that is.
APBT can be a handful and a proven temperment is a huge plus and or gettin a dog bred for what you plan to do with it . If your just lookin for a pet , thousands of shelter / rescue dogs are begging you to take them home and save them from sure death. You get a pet and do a good thing all at the same time ! If your apprehensive about shelter / rescue dogs , im sure there are a vast amount of members here that can ease your mind. I honestly wish i woulda got my 1st one from a rescue. Also , make sure you all are ready for what owning a apbt means.. its a lot of work some times .
