Canine Coat and Nose Color Testing

C128-Canine Coat and Nose Color Test
Collie (Rough)


Presence of tricolor and sable colors. There are two "a" alleles at the agouti locus in Collies which cause the three main coat colors. Each of these may occur with or without merle. At the present time there is no DNA test for merle, but since the merle 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 is typical and eye defects are also common. DNA testing for the "a" alleles in Collies that are sable or tricolor 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 sable, this has not been reliable. Some breeders refer to dogs that are homozygous sable as "clear for sable". Collies are all EE and BB so although tests for the other alleles at these loci are available in our laboratory, these tests are not needed in Collies.

Please select the color of your dog to determine possible genotypes:
Genotype Main Color Nose Color Hidden Color
atat tricolor na none
ayay sable na none
ayat sable na tricolor
Any single tested allele - $55.00*
Each additional allele - $20.00*
*subject to 5% GST 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.
HealthGene requires a blood sample (at least 1ml of whole blood in a purple top EDTA tube) for testing 3 or more alleles. If testing less than 3, a sample collection kit (cheek swab collection) can be ordered online following the link: 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.
