Note the color of their noses compared to the nose of the light Blue Weim in the photos above. The Gray Weim is a dilute brown/chocolate, the Blue Weim is a dilute black. Gray Weimaraner next to a Blue Weimaraner, both typical in coat color. Thus, very light Blues may look lighter than a Mouse-Gray. Blues too can range from very dilute to a very dark Blue. We have Silver-Gray, Gray and Mouse-Gray that vary in how dark they are, but they are all bbdd. We must remember that the difference between blue and gray in Weimaraners is tonal, not the degree of dilution. Some Blue Weimaraners can be so light as to appear gray. In other words, it can make some dogs lighter than others. The dd pair makes the bb chocolate/liver into the light tan that we call Weimaraner Gray or Silver-Gray (bbdd), and it makes Bb of BB black into a charcoal colored dog that we call Blue (Bbdd or BBdd). It is commonly accepted that all Weimaraners are dd that is, all Weimaraners, both Blue and Gray, are diluted and never fully pigmented. Because D is dominant, a Dd (or DD) individual will be fully pigmented and there would be no dilution of coat color. The dominant D causes full pigmentation whereas the recessive d produces a dilute pigment. The b is still there and can and does get passed onto the dog’s offspring, but it is not visible as the dogs phenotype (the physical characteristic that you can see).Īll Gray Weimaraners are bb. Bb individuals will also be black because the dominant B “masks” the b. Since these genes come in pairs, a dog could be BB, Bb or bb. The dominant B produces a black coat color whereas the recessive b produces a liver or chocolate coat color. If present, the dominant gene will determine what you see and will always express itself, “hiding” the paired recessive. In other words, B is dominant to b, and D is dominant to d. Dominance is noted with a capital letter and recessives with a lowercase letter for that allele. Each of these genes may be dominant or recessive. The B genes work in pairs, with one of each of these two alleles inherited from each parent. While there are many loci and alleles involved in the Weimaraner’s coat color, there are only two loci that are important for the Blue versus Gray coat color in the Weimaraner, the Locus B pair and Locus D pair.
