If you sign up for a MYKC account(free) you can check the health tests done on not just the parents of any puppies but also grand parents, great grand parents, ggg parents & gggg parents. Labrador puppies should have at least 5 generations of hip scored dogs behind them if not more depending on how far back the KC updated records go, some dogs make not have their health testing recorded because they were registered before computer records were in place.
There should also be elbow scores recorded & TBH no Labrador with an elbow score that isn't 0 should be bred from as there are enough dogs in the gene pool for any dog with a higher to not be used.
They should also have a current clear eye test certificate done within a year of any litter being born) plus DNA normal or carrier(one parent only) tests for Centronuclear Myopathy (CNM), Exercise Induced Collapse (EIC), Hereditary Nasal Parakeratosis (HNPK), Progressive Retinal Atrophy (prcd-PRA) & Skeletal Dwarfism (SD2).
This is a Kennel Club database for DNA testing in Labradors.
