A brindle is light when the overall appearance is of a red dog Have a look at the Whippet below. It is an unstable allele that causes some cells in the body to act as KB (dominant black) and some to act as ky (non-black), in a similar way to a chimaera (fusion of two embryos) or to a tortoiseshell cat (X-chromosome inactivation). Interestingly, a form of mosaicism in humans results in a brindle-like pattern known as Blaschko lines. There are currently no commercial tests available for the kbr allele, but the allele has been identified by at least one laboratory. A brindle dog will have liver (brown) stripes if it is bb on the B locus, blue stripes if it is dd on the D locus, A brindle is light when the overall appearance is of a red dog Apart from horses and dogs, one of the only other species that appears to have a similar brindle pattern is domestic cattle, like the bull above. In fact, in horses there is no gene for brindle, and when brindle occurs it is always indicative of a chimaera. Because the brindle gene allows expression of the A locus, any A locus coat patterns can show brindling on their red sections. Liver and Dilute Brindles Brindle is a specific coloring in dogs, specifically brownish or tawny with streaks of other colors. These two dogs are brindle with saddle markings(atat plus the RALY saddle tan modifier, see the Agouti page). The main way we can tell this Skye is brindled is simply its muddy-coloured coat - this shade and on the chest and legs is almost white. The base colour on a brindle can vary as much as red can usually vary, from a deep Irish Setter colour to a light cream. The Cardigan Welsh Corgi also shows white in the irish spotting pattern. There is one apparent exception to the rule that only the tan areas on a dog show brindle striping. Have a look at the Whippet below. the Skye Terrier just appears to be a muddy grey/brown. This accounts for examples of dogs that appear to have brindled saddles but no brindling on the legs. If they don't have many photos, follow their links to a regional club or a local breeders' website. Note whether the ears are floppy or upright and the length of the tail. The thickness of the stripes can vary, so the dog may look predominantly dark or predominantly red. Sophie, submitted by Helen Lottridge Brindle on a Greyhound is not super common, but when they do have brindle, they have a huge range. This Staffie shows even heavier black striping than the Greyhound above. Long, wirey and curly fur can obscure brindle markings by making the stripes less distinct. Brindle Merles Sometimes dogs with black stripes and a very light cream base (see above) are also referred to as silver brindles. As with the Staffordshire Bull Terrier cross shown above (submitted by Ally Stern), the effect can be very subtle. on the sable would be) Brindle dogs are not chimaeras, however, but they are mosaics, which is when different cells in the body become genetically distinct during development. kbr sits between the two. This is particularly common in Whippets, If the Skye above were to be clipped down, it would look something like this. Silver Brindle As with the Staffordshire Bull Terrier cross shown above (submitted by Ally Stern), the effect can be very subtle. can see a large clear area on the dog's side. However, the light base colour can make the stripes seem greyish (see below). A brindle with stripes that appear to be broken up into shorter stripes and spots may be a merle. Crossbreed photo by (unknown) "Missing" Stripes on the legs and head. The dark (eumelanin) stripes on a brindle can be affected by liver, dilution, greying or merle, and the light/red (phaeomelanin) stripes can be affected by the Intensity locus. No time to read the whole thing? Brindle typically appears as black stripes on a red base. kbr sits between the two. The visual effect is somewhere inbetween tortoiseshell in cats and dog brindle, as the effect on more heavily marked rabbits is of large stripe-like patches. Technically brindle is a marking pattern, but … Brindle Merles Liver and brindle do not occur together on many breeds, however the combination is fairly common in Pit Bull types. Links to studies: occurs almost exclusively on brindles and not on normal solid reds or sables. In the first picture the brindle appears normal, however in the second picture you I have categorized them into best overall, brindle pattern-themed names, dog names for various coat colors, and male/female big dog names.
