dont think its a good idea
i just dont see it being worth the risk really and CDA is incurable.
"Treatment: There is no cure for color dilution alopecia. Treatment is aimed at controlling secondary skin infections and avoidance of harsh grooming products and abrasive brushes which can worsen hair breakage. Mild shampoos containing sulfur and salicylic acid may be helpful in reducing follicular plugging. In some dogs, supplementation with oral melatonin or retinoids can be helpful to stimulate partial hairgrowth."
the main dilutes I know of that have the issues with CDA :
isabella/fawn/pink (in some circles)
isabella i was always under the impression came from Chocolate X Blue and tended to have the higher risk factor. correct me if i am wrong.
i honestly believe part of the reason you dont see them very often at shows is because of that higher risk making it harder to keep them in coat.
Thin coats on the dilute colors are not usually due to allergies and the dilutes don't seem to have any more skin problems, with the exception of CDA, than blacks or reds do.
If the coat looks good from 2 or 3 feet away it probably is good but most puppies in dilute colors have decent enough coats the thinning due to CDA takes place over time so a dog who had a decent coat at 10 months might well be bald at 5 years.
The dermatology texts say that over 90% of all blues will at least have thinning hair and many will thin to the point of being bald over most of the body. Fawns seem to have a better chance of retaining their coats with about 75% of the fawns having extensive hair loss due to CDA.
The literature also says that the darker the coat color in a dilute dog (steel blue in blues and carmel in fawns) the better the chance they will retain most to all of their coats. This seems to be the case in the blues and fawns I've known over the years.
There are a few dilute dogs whose coats are fine, who don't lose hair, don't have CDA and never go bald but they are few and far between."
dobermans to me are always a prime example of CDA this is the link to the quoted text : Color Dilution Alopecia - DPCA Breeder/Exhibitor Education
dogs with CDA are relatively healthy except for the hair loss related issues. but its still breeding in a color that presents an issue. at which i would say it wasnt worth it.
