Why test for dilution?
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.
For most breeders dilute puppies are particularly desirable.
In different breeds the dilute colours are described as blue, silver, slate, lilac, lavender, fawn or isabella. That's lots of different names for the same colours! But no matter what you call it, the dilute colours are stunning.
Our test for dilution is based on the DNA sequences described in Drögemüller et al, 2007.
