Canine DNA Coat Color Testing
DDC Veterinary offers DNA testing for coat color genotypes among several dog breeds. By identifying the color genotype of the parents, clients can more accurately predict the colors of future progeny. Breeders can use DNA testing as a tool to more effectively manage mating patterns and make more informed selection decisions.
DNA samples can be collected easily at home using buccal (cheek) swabs provided as part of a free DNA sample collection kit.
Dogs can be DNA tested at ANY age.
A detailed DNA report for each canine tested will be mailed within 10 business days of receipt of the samples. A summary of the result will be emailed the day of completion.
The cost for testing (per canine tested) is $58 (US) for the first locus test and $20 for each subsequent coat color locus tested requested at the time of sample submission. Payment can be submitted with the return samples.
Coat Color DNA Testing options include:
E Locus
Most often used to determine the relationship of the Black (dominant) to Yellow (recessive). The ee genotype results in a yellow phenotype. (“yellow” can represent a variety of lighter colors including apricots, reds, creams, and whites)
B Locus
Associated with the presence of chocolate (also commonly referred to as liver or brown). The bb genotype results in a chocolate coat phenotype and liver noses among yellow dogs.
For example, with Labrador Retrievers there are 3 accepted coat color phenotypes (what you can see): Black, Yellow, and Chocolate. However, there are 9 possible reported genotypes (what you cannot see) for the E and B loci and therefore 81 possible breeding combinations.
- Black Coat: 4 possible genotypes- EEBB (black with no hidden colors), EeBB (black with hidden yellow), EEBb (black with hidden chocolate), EeBb (black with hidden yellow and chocolate)
- Yellow Coat: 3 possible genotypes- eeBB (yellow with hidden black), eeBb (yellow with hidden black and chocolate), eebb (yellow with hidden chocolate- dogs will exhibit liver noses)
- Chocolate Coat: 2 possible genotypes- EEbb (chocolate with no hidden colors), Eebb (chocolate with hidden yellow)

D Locus
Associated with the dilution or lightening effect of the solid colors Black and Brown, with D being the dominant allele, the dd genotype results in the diluted effect.
