> Can I ask, if one is aware of a sire that is hereditary clear, does that ensure offspring will be clear or a carrier regardless of the dam,s health screen results? Someone told me that so please don't shoot the messenger!
Clear for prcd_PRA? In theory yes if one parent is clear than the worst a puppy from that parent could be is a Carrier. However mistakes can occur - there have been cases where hereditary clear status has been subsequently been proven to be incorrect - not something that happens often but something to be aware of.
These days there is no excuse for breeders not to be testing their bitches (not just relying on using a "clear" stud dog) so would always recommend you source a Cocker puppy from a litter where both parents have had all the recommended tests, not just one.
