Canine Coat and Nose Color Testing

C128-Canine Coat and Nose Color Test


Presence of "true red", black or black and tan or red with dark tips and chocolate or chocolate & tan coat colors, and black or brown nose in the following breeds:
? Miniature Long-haired Dachshund
? Miniature Smooth Dachshund
? Miniature Wire-haired Dachshund
? Standard Long-haired Dachshund
? Standard Smooth Dachshund
? Standard Wire-haired Dachshund
There are two "a" alleles at the agouti locus in Dachshunds (ay and at) which cause the two main underlying coat color patterns: sable and black-and-tan (or chocolate-and-tan). Note that color terminology in Dachshunds is a bit confusing in regard to sable and red. Sable is a reddish color with darker tips on some hairs. "Clear red" is a solid red with no hint of black tips on any hairs. However, Dachshund owners have often used these terms interchangeably. Each of these agouti colors may occur with or without dapple. At the present time there is no DNA test for Dapple (or merle), but since the dapple pattern is exhibited by the Mm heterozygotes, the phenotype is predictive of the genotype. Note that "MM" dogs are primarily white, and conscientious breeders avoid producing such dogs since deafness and eye defects are common. White spotting also occurs in Dachshunds and no DNA test is yet available to predict this. It is often called piebald in Dachshunds and is inherited as a recessive. Each of these agouti colors may also occur with or without brindle. Dachshunds that have at least one ay allele will be full-body brindles. Dogs that are at at will have brindle only on their "points", i.e. they will be brindle where they would otherwise have had tan. At the present time, DNA testing is not yet available to detect the brindle allele. Dogs which are "ee" may carry brindle but would not express this pattern. DNA testing for the "a" alleles in Dachshunds that are sable or black-and-tan (or chocolate-and-tan) allows breeders to better predict the colors of pups from particular matings. Although some breeders believe they can "see" the difference between a homozygous and heterozygous fawn, this has not been reliable. There are two common alleles in Dachshunds at the E locus: E and ,b>e. True red Dachshunds are "ee" and this genotype masks the expression of brindle and tan points. Dachshunds have two alleles at the B locus: B and b. Dogs that are "bb" will have chocolate-and-tan coats if they are at at, but only their noses will be chocolate if they have an ay or are "ee". Note: a coat of intermingled red and black or brown hairs, called "boar", also occurs in this breed. We have not had the opportunity to study this color and therefore carriers can not be distinguished at this time.

Any single tested allele - $55.00*
Each additional allele - $20.00*
* subject to HST for Canadian residents only.

Note: Mask gene (Em) is considered as an individual test, separate from other alleles in E locus.

To help you to calculate the proper amount, please review the following example:
Testing for 3 alleles - E, B, and D - should be calculated as $55 + $20 + $20 = $95.00.
The price will be automaticaly calculated during the process of ordering a sample collection kit.
The following sample(s) can be submitted for the testing:
1. Blood sample in a lavender top tube.
2. Cheek swabs. Sample collection kit online: Order a Sample Collection Kit
Test results are usually available in 10 Business Days from the moment the samples arrive at the laboratory. Test results can be reported by e-mail, fax, or by phone.
HealthGene will provide a certificate for each test result.
