DNA testing for health and appearance genes in dogs

Learn about one of the tests we do: D locus dilute d2 (Chow Chow type)

Dilution is the colour gene that dilutes brown to silver, and black to a blue or slate colur. Dilution is a recessive trait. This means that dogs can silently carry the dilute gene, without being dilute themselves. Dogs like this - dilute carriers - can potentially produce dilute puppies.

The dilute type 2 test is for a rare form of the dilution gene that so far has been found in Chow Chows, Sloughis and Thai Ridgebacks. It can create the dilute coat colours by itself or in combination with the common dilute gene.
