I am not sure how this nose color craze started, but many of us that have been in the pit bull community for years and continously reseach the breed, are absolutely baffled with where the "red nose" and "blue nose" craze came from. What I can say is that most backyard breeders looking to make a quick buck have continued and heightened the craze and are selling these "rare" dogs at a very high price to unsuspecting and uninformed individuals and families. The things is people...a red nose and a blue nose isn't any different than any other pit bull out there. It is just a color.
There are many "types" of American Pit Bull Terrier. You have show dogs, working dogs, and various line types. One of the most famous line types is the Colby line, and it is the Colby's that started the fascination with APBTs with dog fighting and owning them as family pets.
There are different breed types. The breed type are basically just the standards/appearance of the APBT. For example, the APBT is a medium sized dog that is well built and muscular. It ranges from an average of 35-65 pounds. This is an example of breed type. It is sinmply the characteristics of the dog. Red hair, white hair, brindle with blaze, etc. These are all breed types.
Then there are line types. Line types are created by the result of a specific breeding programs effects on the breed type. You have the Colby line of dogs, and this is a good example to use. After, oh let's say about 100 years of line breeding, they have produced a distinct looking dog. These dogs are typically black brindle with white blazes or completely white heads. There is also a similar type with fawn and white. This is where it gets confusing...just because a dog happens to have that coloring and markings, doesn't mean it is a true APBT from the Colby line. Sadly, the Colby line has been mixed with many other lines and other breeds, that it is uncertain to many of us if a true Colby line really exists anymore. Many breeders tote that they have the Colby line, but no one can really prove it. Sure, they may have "papers", but anyone can make a paper for a dog. The AKC is known to "paper" backyard breeders! How twisted is that!?!? Money talks.
Another line type is the sorrell dogs. These dogs are usually fawn with no other colorings and a black muzzle and nose. These dogs are very "average" looking in appearance, but are still gorgeous, nonetheless. But aren't all ABPTs gorgeous?
Many APBT experts guess that the Old Family Red Nose dogs out of Ireland started this trend of "red nose" dogs. People started calling them, "Old Family Reds" and "Red noses" because they had a very obvious red coat with red nose. No one that I know of has ever seen a real Old Family Red Nose, as that was many, many years ago. But just from descriptions when you read about the history, they sure do sound beautiful!
People started calling dogs by their nose color, as if it was different than white, black, pink, or brown. Many people even think that they are different breeds. They are not any different than the brindles, the fawns, the whites, and the black dogs.
I get questions from clients at my clinic and from vet school students in my research classes who have APBTs saying, "I have a red/red nose, what breed is my dog?" My reply: "Guess what? It is a American Pit Bull Terrier with a red nose, rather than pink, black, or brown." The same goes for any APBT with a colored nose, coat or whatever. They are the same breed. They are APBTs.
There is only one pit bull and that is the American Pit Bull Terrier.
If they have a red nose, pink nose, blue nose, white coat, red coat, brindle coat, cream coat, fawn with white patches, three legsm or one eye, it doesn't matter. They are still 100% American Pit Bull Terriers (unless they are known mix breeds, which most are these days).
I hope that this didn't upset anyone, but I wanted to help clarify a HUGE misconception for many pit bull owners. Research this topic on the web, and you will find the same information.
It shouldn't matter what color your dog is. Just love him, treat him with respect, train him every day of his life, socialize him every day, and make him a member of your family. The color of nose will not change the way that your APBT will love you unconditionally.
