ok i heard that rednose pitbulls cannot produce black pigment.. and i also heard that there is a so called (clear rednoses) that produce black hair in the coat and black whiskers and black/brown nails .. i have a pure breed red nose APBT and she has some black hair in her coat and some dark nails.. why is this? is it the so called (clear rednoses) ??

I dont know where you "heard" these things from but stop listening immediately. The debate about what a dog can or cannot produce depends on genetics. i have been around dogs for a little while now and HAVE NEVER EVER HEARD OF CLEAR REDNOSES. my suggestion to you is to find a real mentor that has a clue about bulldogs and go from there.

I'd advise a little more thorough responses. What does red can not produce black mean? I am pretty sure that I have a black brindle and white dog with a red red nosed momma so...she did produce him. I am pretty sure that there are red dogs with black noses in many breeds. I'd revisit the statement "can not produce" or offer more qualification...(in fact if you follow the link I posted you will see a red dachsund with a black nose ) |

I have a black nosed dog who appears red but his coloring is considered fawn because he cannot be a truly "red" dog. He's red fawn. For your pup out of a red rednose the dad would also have to be dilute to produce dilute pups, it's a recessive gene. Like how breeding blue to blue only produces more dilute colored dogs. A true dilute colored dog will have no black on them, their genes don't allow the color to be produced.

If your dog is indeed rednosed(color) it won't have black hairs in it's coat. All the areas that would have been black pigmented will be diluted to liver, like the nose leather. But it sounds like maybe you think that rednose is your dog's breed, rather than a color.
The "clear red" color that you've heard about actually has no black hairs anywhere in the coat, including the whiskers, but the nose is black. I've also heard it referred to as recessive fawn. This is caused at a different locus than the one that controls the rednose dilution. You can have both occur in one dog, but it would just look like a red rednose dog. An example of a breed with "clear red" coloration is the Irish setter. As for what can produce what, it all depends on the individual genetic makeup of the dog. In teewig's example, the dam(red/rednose) was either a "clear red", which is the only way the brindle could have been carried unexpressed in non black dogs, or a liver dog, in which case she was genetically black(diluted) and also carried brindle. |

I was of the opinion 2 rednoses can't produce black until I read this from Willis book "Genetics of the Dog."
"It can be seen that the two breeds are solid colored (AA) and differ only in that one is unable to produce black pigment because it has the ee (red) combination while the other is unable to produce black pigment because of the bb (chocolate) combination. All other (coat color) genes in the two breeds are identical & are thus unaffected by the crossing, but in the B/E loci, the combination becomes Bb & Ee & thus black is now formed." So according to Willis, 2 rednoses CAN produce black IF neither rednose is not a result of dd alone. |

EDIT - forgot to add, as for your dog ishy, maybe the "black" hairs you're seeing are actually chocolate or dark blue? I have a rednosed male & it looks like he has one black toenail, but if you look closely in the sun, you can see his toenail is not black, but actually dark chocolate.
I have always heard the best way to tell is to look at the whiskers. A sable dog has black whiskers, where a non-sable ("clear" red) will have red whiskers. Rednoses can be either brindled, clear, or sabled but in brindles & sables the whiskers can be either be blue or chocolate. Clears almost without exception have red. Hope this helps! ![]() |

Boy am I learning about dog color genetics!
Peanut is red with white markings with a pink and brown butterfly nose. Her nails are clear or tortoiseshell brown. She has a patch of hair on her tail that is either black or extremely dark brown and her whiskers are either black or white. We don't know anything about her parents. Not even if they were both APBT. |
