So the background story is this: When I adopted Riley at 2 mo. old (I was 2nd adopter, 1st adopter chained him outside and the owner, my cousin, took him back) She told me he was a pitbull. She owns his mother, her boyfriend owns his father, and my other cousin has one of his sisters. At that age bully breeds are hard to tell so I just said 'ok' and figured he was.
As my first 'pitbull' I wasn't prepared for the immense personal feelings of discrimination against him from other people and sadly enough, family too. I've never discriminated against anything based on background or stereotypes so I was in for a culture shock. He was the sweetest, most loving puppy ever, and had never barked let alone growled ever so far.
As he got older and developed more though, I started to notice that he hadn't lost a lot of his 'puppy' qualities like loose and wrinkly skin, and developed some new features around the four month mark; black spots, which he got more of over the few months following. Almost like freckles. (He's all white). He'll be 11 mo. old on March 23rd, so he could possibly still develop even more.
Then I started getting all these different breed guesses when people would ask me what he was. As I looked into them I began to wonder myself. Especially since I would love to find out he wasn't a pitbull so I could show my family just how discriminating and naive' they were. So I decided to get one of those DNA breed tests done. It said it compared with over 100 breeds and listed them.
While I am still waiting on the results, I have a new worry now. A lot of the breed guesses I've gotten that look a LOT like Riley are not on the list. So I am wondering if there are any breed experts that would like to give me an opinion on his breed, since he may be one or a mix of those not listed on the DNA test. I've included younger and older pictures. Plus it could be fun to compare to the results when I get them back which I will post.
Thanks!

P.S. These are the breed (and mixes) guesses I have had so far (the starred ones are those not listed with the DNA test):

APBT*
Staffordshire Bull Terrier
American Bulldog*
Dogo Argentino*
Dalmation
White Labrador Retriever
