Silver Labrador retrievers are just a different coat color than other dogs of the breed, and are no better or worse in terms of health or performance. As of 2015, many fans of Labrador retrievers oppose the breeding of silver Labs, because silver is outside the breed standard.
Silver Labs do not suffer from any unusual health problems as compared to other Labs, and their gene pool is not particularly inbred. As of 2015, there are seven distinct genetic lines within the silver subtype. This is considered diverse for a coat type within a single breed. They do well in field trials and as hunting dogs, but cannot be shown as Labs at dog shows run by the American Kennel Club due to their coloration. The only colors recognized by the breed standard for purebred Labs are yellow, black, and chocolate. As of 2015, many breeders suspect Silver Labs are crossbreeds.
