![]() And it’s easy for breeders to increase the odds of blue brindle Pitbull puppies by making savvy breeding choices. This means that if Pitbulls existed in the wild, expression of a blue brindle coat would be easily obscured by other coat types instead.īut of course, they don’t. The brindle gene is masked by some genes, but not all.Īnd the dilute gene is recessive, which means it is only expressed when a dog has two copies of it. The black gene is dominant, which means it is expressed whenever it is present. So that the black appears blue, and the red appears fawn.īlue brindle Pitbull puppies receive two copies of the d gene: one from each parent. The dilute gene reduces the amount of pigment in each strand of hair. And as handsome as that is, blue brindle dogs have one more extra special element: Pitties with just the black and brindle genes have black and red brindle markings. The brindle gene causes the narrow stripe pattern on blue brindle Pits.īrindle dogs have one or two copies of the brindle gene (from one or both parents).īlue brindle Pitbull puppies with only one copy of the brindle gene only develop a brindle coat if they don’t inherit an alternative gene which masks it from their other parent. Next comes the brindle gene, which has the unexpected abbreviation K br. It triggers production of the black pigment eumelanin.īlue brindle dogs only need one copy of this gene, from one of their parents. Sometimes to truly appreciate what makes a color special, it’s fun to look at the chemistry going on at a genetic level.īlue brindle dogs owe their looks to a very particular genetic recipe: The black geneīlue brindle starts, counter intuitively, with the black gene, known as B.Īll blue brindle dogs have a copy of the B gene. So, they’re sometimes called blue nose brindle Pitbulls. The exact width and spacing of them is as unique as a fingerprint, but they’re always pretty narrow.īlue brindle stripes are gray with soft fawn in between them.īlue brindle Pits also have blue noses. What About Brindle?īrindle is a pattern of stripes. In dog color parlance, blue means gray.īut it has to be said that ‘gray’ just doesn’t do these coats justice – it’s a very special shade of gray indeed. Of course, they aren’t literally blue like the sky. ![]()
