THE BIG DEBATE. MOST PEOPLE DO NOT KNOW THE DIFFERENCE BETWEEN THE TWO BREEDS.
If you are just looking for a pet, to love and enjoy, I would suggest going with a rescue or shelter dog. There are a lot of purebred quality pits there. If looking for a pet, pick something with more of a layed back temperament, but not shy or fearful. Something on the smaller side.
If you have your heart set on a papered dog, look hard and careful, as there are way more dis-reputable people than there are good ones.
The amstaffs and pits can both be hyper, and dog agressive depending on the bloodlines, and parentage.
Many UKC dogs are amstaff crosses anyway, so you may be able to save a little money by going with what I all a UKC amstaff.
As a rule, the APBT
is less expensive. There are also not as many people breeding the amstaffs, so it may be easier to find a good APBT
. Also, it depends on the look you are searching for. True APBTs tend to have a leaner appearance, than the amstaffs or UKC show dogs. There are also some amstaff lines that tend to be more layed back. However, the ones I have, are not. LOL.
Where are you located, and exactly what are you looking for? I can give you some names of reputable breeders of both near you, hopefully.
