This colour is tied to breeding for harmful extremes
Merle-to-merle pairings can produce deaf or blind puppies. Colour is not quality — breeding for looks at the cost of health harms dogs.
Three questions for the breeder
- Is the second parent proven not to carry merle — with a genetic test, not just a look at the coat?
- Do both parents have a BAER hearing test and a current eye examination on file?
- Have puppies from this or an earlier pairing been born with hearing or vision damage?
