All depends on who you want to believe. Some people used other breeds in THEIR recreation, but it was not along recognized lines. The constant reduction of the amount of white and quite possibly the loss of the black in the standard was primarily to remove signs of those crossbreedings from the type. When the recognition of the breed happened by the RSCE, and the writing of the standard by the same organization in 1989, it was based on a few select "pure" dogs presented to the organization, as well as historic info gathered by the CEPRC about the breed. Shortly after that, a show was held to help register dogs that fit this bill, believed to be of presa lines. However, as the story goes, the person in charge of approving the dogs was appointed by the RSCE, and not familiar enough with the breed, and he basically accepted everything that was presented in front of him as breed-worthy presa, including a lot of bull-type mixes and owner creations. From that point on, it became the goal of the CEPRC to weed out these atypical specimens, which is why they held registro and conformacion up until the recognition of the breed in the 2000's. That was over 10 years of viewing and approving or rejecting dogs before they could be allowed paperwork to breed. Of course, there are always those that skirt the parameters and continue to make their own versions of things, and then sell them as "rustic" and "old world" or "original" instead of the more appropriate "atypical" and "unstandard". As for your dog, I'm sure I couldn't say, not having seen it. There is of course a difference in a puppy coat and adult, and oftentimes you will also notice a difference in a fawn and a brindle coat texture. The dog can be soft when well cared for, and shiny in the case of darker colors, but still have the coarse hairs of the proper coat. It's hard to explain in words and not in coats in front of you...but the hair should still be coarse, never satiny smooth like a pit bull. Diet can definately play a part in the coat, but it should always remain at base "Coarse". When I tried out a few of my girls on Blue Buffalo, I saw them lose one coat, and grow in a different more lusturous coat...but it was still coarse, not satiny. This is an example of one of my girls on Blue Buffalo. As you see, the dark coat was very lusturous, some would call it shiny; but her coat was still "coarse" when you run your hands over it. BTW, Coarse does not mean "Rough" or "Sharp". This is a friends APBT. I'm not sure this pic is close enough for you to see the difference to a great degree, but the hair on the APBT is smoother, lies flat and is hard to discern the different strands. This dog feels like satin when you pet him (If you can get him to stay still long enough). It's kind of like the difference between a human's coarse hair and fine hair. Again, I don't have your dog in front of me, so I can't say if we're talking the same thing. It could be your dog actually does have an atypical coat now, for all I know. I'm giving it the benefit of the doubt, that it might be fine, and we're just not talking the same language.
