Are you an experienced breeder? Did your Dame and Sir have all the testing prior to breeding? This color is a genetic flaw from what I have read I'm no breeder by any means. If you are truly wanting to breed to protect the breed then I would defiantly find out if your sir or dame or both crays this gene. The chocolate's are usually healthy thank god you didn't have a blue. If you seal these babies I would seal them as pet only no breeding rights with a spay neuter contract. Wish I could help more
