Quick answers

What health tests should Lab breeders do?

The Labrador Retriever Club asks for OFA hip and elbow evaluations done at or after 24 months, an eye exam by a board-certified ophthalmologist within a year of breeding, and DNA tests for EIC and the dilute (D-locus) gene. It also highly recommends CNM, PRA-prcd and cardiac screening. Check both parents in the OFA database. Answer page →

The core clearances (OFA CHIC for Labradors)

TestMethodWhat a good result looks like
HipsX-ray read by OFA (or PennHIP)OFA Excellent, Good or Fair
ElbowsX-ray read by OFANormal
EyesExam by a board-certified veterinary ophthalmologistNormal / clear
EICDNA testClear, or carrier bred to a clear dog

Check OFA’s site for the current CHIC requirements, which can change.

Additional DNA tests many Lab breeders run

ConditionShort descriptionInheritance
CNM (centronuclear myopathy)Muscle weakness in young dogsRecessive
PRA-prcdProgressive retinal atrophy, leading to blindnessRecessive
HNPKHereditary nasal parakeratosis (crusty, dry nose)Recessive
SD2Skeletal dysplasia 2 (shorter legs)Recessive
DM (SOD1)Degenerative myelopathy, late-onset spinal diseaseRecessive with incomplete penetrance

The key point: carriers are fine to breed if paired with a clear dog. Avoid any litter where both parents carry the same mutation.

How to verify

  1. Ask for the parents’ registered names and OFA numbers.
  2. Look them up on the OFA database.
  3. For DNA results from other labs, ask to see the certificates. Paw Print Genetics, UC Davis, Embark and others issue them.

For pet owners

Already have your Lab? A consumer DNA kit (Embark or Wisdom Panel) screens for many of these conditions and reports coat-color genes. That’s useful for vet records and for spotting EIC or PRA risk early. Compare them in best DNA test for Labs.

Frequently asked questions

How do I verify a breeder's OFA results?

Search the parents' registered names on the OFA website (ofa.org). Results that are public are listed there.

Is a consumer DNA test enough for a breeding dog?

For breeding decisions, most breed clubs prefer OFA-recognized labs and official X-ray evaluations. Consumer kits are useful for pet owners.
