Breeder's Guide to OFA Health Certifications: What Tests You Need

Health testing is the backbone of responsible dog breeding. The Orthopedic Foundation for Animals (OFA) maintains the largest database of canine health screenings in the world. Whether you're a new breeder or looking to improve your program, understanding OFA certifications protects your dogs, your buyers, and your reputation.

This guide explains which OFA health tests you need, when to do them, and how they fit into your breeding program. We'll cover everything from hip dysplasia screenings to genetic disease panels, so you can make informed decisions about your breeding stock.

What Is the OFA and Why Does It Matter?

The Orthopedic Foundation for Animals (OFA) was founded in 1966 to reduce the incidence of inherited diseases in dogs. They maintain public databases of health test results, making it easy for breeders and buyers to verify a dog's health clearances.

OFA certifications aren't legally required by federal law, but they're industry standard for responsible breeding. Many breed clubs require OFA testing for registration or breeding rights. Buyers increasingly expect to see OFA numbers before purchasing a puppy. If you're serious about breeding healthy dogs, OFA testing is essential.

Core OFA Health Tests Every Breeder Should Know

OFA offers evaluations for dozens of conditions. The specific tests you need depend on your breed, but most breeding programs include these core screenings:

Hip Dysplasia Evaluation

Hip dysplasia is one of the most common inherited orthopedic problems in dogs. OFA evaluates hip X-rays and assigns grades: Excellent, Good, Fair (all passing), Borderline, or Dysplastic (mild, moderate, severe).

• When to test: Dogs must be at least 24 months old for official OFA hip certification
• Process: Your vet takes hip X-rays under sedation, then submits them to OFA for evaluation by board-certified radiologists
• Cost: Typically $35-45 for OFA evaluation fee, plus vet fees for X-rays and sedation
• Results: You receive a certificate and OFA number if hips pass (Excellent, Good, or Fair)

Hip dysplasia affects many large and giant breeds, but it can occur in any size dog. Breeding only dogs with passing hip evaluations significantly reduces the risk in puppies.

Elbow Dysplasia Evaluation

Elbow dysplasia includes several developmental problems that cause arthritis and lameness. OFA grades elbows as Normal, Grade I (mild), Grade II (moderate), or Grade III (severe).

• When to test: Dogs must be at least 24 months old for certification
• Process: Similar to hip evaluation—X-rays submitted to OFA for grading
• Important breeds: Essential for Labrador Retrievers, Golden Retrievers, Rottweilers, German Shepherds, and other large breeds
• Best practice: Only breed dogs with Normal elbows

Cardiac Evaluation

Heart disease can be inherited in many breeds. OFA offers two levels of cardiac clearance: basic auscultation (listening with a stethoscope) and advanced echocardiogram evaluation.

• Basic exam: Board-certified cardiologist listens for murmurs or arrhythmias
• Advanced exam: Ultrasound evaluation to detect structural problems like dilated cardiomyopathy
• When to test: Can be done at 12 months for basic exam; some breeds need annual re-checks
• Critical breeds: Cavalier King Charles Spaniels, Doberman Pinschers, Boxers, and other breeds prone to heart disease

Eye Examination (CAER)

The Canine Eye Registration Foundation (CERF) is now part of OFA and called CAER (Companion Animal Eye Registry). Board-certified veterinary ophthalmologists examine dogs for inherited eye diseases.

• What they check: Progressive retinal atrophy (PRA), cataracts, glaucoma, and other hereditary conditions
• When to test: Initial exam at 12-24 months, then annually because some eye diseases develop later
• Cost: Typically $40-75 per exam
• Note: Eye clearances expire after one year, so breeding dogs need annual re-examinations

Patellar Luxation Evaluation

Patellar luxation (loose kneecaps) is common in small and toy breeds. OFA evaluates patella stability and grades them as Normal or Grades I-IV luxation.

• When to test: Dogs must be at least 12 months old
• Process: Your regular vet can perform the exam and submit results to OFA
• Common in: Chihuahuas, Yorkshire Terriers, Pomeranians, and other small breeds
• Breeding standard: Only breed dogs with Normal patellas

Genetic Disease Testing Through OFA

Modern DNA testing has revolutionized dog breeding. OFA partners with genetic testing companies to track results for inherited diseases. A simple cheek swab can reveal whether your dog carries genes for dozens of conditions.

How Genetic Testing Works

Most genetic diseases follow simple inheritance patterns. For recessive diseases, dogs can be Clear (no copies of the mutation), Carrier (one copy), or Affected (two copies). Understanding genetics helps you make smart breeding decisions.

• Clear x Clear: All puppies will be clear
• Clear x Carrier: Average 50% clear, 50% carriers (no affected puppies)
• Carrier x Carrier: Average 25% clear, 50% carriers, 25% affected
• Never breed Affected x Affected for serious diseases

Common Genetic Tests by Breed

Different breeds need different genetic panels. Here are examples of important tests for popular breeds:

• Labrador Retrievers: Exercise-induced collapse (EIC), progressive retinal atrophy (prcd-PRA), centronuclear myopathy
• Golden Retrievers: Progressive retinal atrophy (GR-PRA1 and GR-PRA2), ichthyosis, muscular dystrophy
• German Shepherds: Degenerative myelopathy (DM), multidrug resistance (MDR1)
• Poodles: Progressive retinal atrophy (prcd-PRA), von Willebrand disease, neonatal encephalopathy
• Dachshunds: Progressive retinal atrophy (cord1-PRA), mucopolysaccharidosis

Check with your breed club for recommended genetic tests. Most clubs publish health testing guidelines on their websites.

Creating Your Testing Timeline

Smart breeders plan health testing before breeding age. Here's a typical timeline for a breeding prospect:

1. 8-12 weeks: DNA sample collected for genetic testing (can be done at any age)
2. 12 months: Preliminary hip/elbow X-rays (optional PennHIP evaluation), cardiac exam, first eye exam, patellar luxation check
3. 18-24 months: Monitor growth and development, repeat any concerning tests
4. 24+ months: Final OFA hip and elbow certification, update eye exam, cardiac re-check if needed
5. Before each breeding: Verify all clearances are current, especially eyes and cardiac

Understanding OFA Numbers and Certificates

When your dog passes an OFA evaluation, they receive a unique OFA number. This number appears on certificates and in the public database. Understanding OFA numbers helps you verify breeding stock.

How to Read OFA Numbers

OFA numbers follow a specific format. For example: SR12345G24F breaks down as:

• SR: Breed code (Sporting breeds, Retrievers in this case)
• 12345: Individual dog number assigned by OFA
• G: Grade (E=Excellent, G=Good, F=Fair for hips)
• 24: Age in months when X-rays were taken
• F: Sex (M=Male, F=Female)

Elbow numbers use E (Elbow) instead of grades. Cardiac numbers include the date. Eye clearances show the year of the exam.

Cost of OFA Testing: Budgeting for Health Clearances

Health testing is an investment in your breeding program. Costs vary by location and which tests your breed requires, but here's a general budget guide:

• Hip evaluation: $200-400 (vet fees for X-rays/sedation plus OFA fee)
• Elbow evaluation: $150-300
• Eye exam (CAER): $40-75 annually
• Cardiac basic exam: $75-150
• Cardiac echo: $300-500
• Patellar luxation: $50-100
• Genetic testing panel: $100-200 per dog

Expect to spend $800-1,500 per breeding dog for comprehensive health testing. This seems expensive, but it's far less than the cost of producing unhealthy puppies or facing lawsuits from buyers.

What Happens If Your Dog Fails a Test?

Not every dog makes the cut for breeding. Failing a health test doesn't mean your dog can't be a wonderful pet, but it does mean they shouldn't reproduce.

If your breeding prospect fails an OFA evaluation:

1. Accept the results: Responsible breeders prioritize health over personal attachment
2. Spay or neuter the dog: Remove them from your breeding program
3. Review your program: If multiple dogs fail, reassess your breeding decisions
4. Be transparent: Share results with co-owners if applicable
5. Focus on the dogs that pass: Build your program around genetically sound dogs

OFA Testing and Licensing Requirements

OFA certifications are separate from breeder licensing, but they often work together. While federal USDA regulations don't require OFA testing, state and local laws sometimes do.

Some states require health testing as part of breeder licensing. For example, certain jurisdictions require hip and elbow certifications for large breed dogs or eye clearances for breeds prone to vision problems. Check your state's specific requirements on our state licensing page.

Even if your state doesn't require OFA testing, buyers expect it. Many puppy buyers research OFA databases before contacting breeders. Having comprehensive health clearances sets you apart from backyard breeders and puppy mills.

How to Submit Results to OFA

Submitting results to OFA is straightforward, but each test type has specific requirements.

General Submission Process

1. Register your dog: Dogs must have permanent identification (AKC registration, microchip, or tattoo)
2. Have the appropriate specialist perform the exam: Board-certified veterinarians for most evaluations
3. Complete OFA application forms: Download from OFA.org or your vet may have them
4. Submit X-rays or exam results: Digital submission is fastest for radiographs
5. Pay evaluation fees: Fees vary by test type
6. Wait for results: Most evaluations take 2-4 weeks

For genetic testing, purchase a test kit from an OFA-approved lab, collect the sample (usually a cheek swab), mail it to the lab, and results automatically appear in the OFA database when complete.

CHIC Certification: The Gold Standard

The Canine Health Information Center (CHIC) is a partnership between OFA and breed parent clubs. CHIC certification means a dog has completed all recommended health tests for their breed.

CHIC requirements vary by breed. For example, Labrador Retrievers need hip evaluation, elbow evaluation, eye exam, and EIC genetic test. Golden Retrievers need hips, elbows, cardiac exam, and eye exam.

Important: CHIC certification means testing was done, not that the dog passed every test. A dog can receive CHIC certification even with borderline hips, as long as the results are public. CHIC promotes transparency, not perfection.

Look for CHIC numbers when evaluating breeding stock. A CHIC-certified dog shows the breeder is committed to health testing and transparency.

Common Mistakes Breeders Make with Health Testing

Avoid these common errors when planning your health testing program:

• Testing too late: Don't wait until breeding age to discover your dog has hip dysplasia
• Skipping breed-specific tests: Just doing hips and elbows isn't enough if your breed needs cardiac or eye clearances
• Not updating annual tests: Eye clearances expire—keep them current
• Ignoring genetic carrier status: Carriers can be safely bred to clear dogs; don't eliminate good dogs unnecessarily
• Hiding failed results: OFA allows private submissions, but transparency builds trust with buyers
• Breeding before clearances: Always wait for final certifications before breeding
• Forgetting to verify sire's clearances: Both parents need health testing, not just your dog

Educating Puppy Buyers About OFA Clearances

Part of responsible breeding is teaching buyers why health testing matters. Include OFA numbers in your sales contracts and puppy packets. Show buyers how to look up results on OFA.org.

Explain test results in language buyers understand. Not everyone knows what 'prcd-PRA carrier' means. Help them understand that carriers are healthy dogs that simply need to be bred carefully.

For buyers researching breeders, we have a comprehensive guide on questions to ask breeders that covers health testing verification.

Beyond OFA: Other Health Registries

While OFA is the most comprehensive, other organizations offer health certifications:

• PennHIP: Alternative hip dysplasia evaluation using distraction radiographs, can test younger dogs
• Embark/Wisdom Panel: DNA testing companies that test for genetic diseases and traits
• Breed-specific registries: Some breeds have their own health databases
• International registries: FCI and other international organizations for imported dogs

These can complement OFA testing but shouldn't replace it. Most buyers are familiar with OFA, making it the standard for verification.

Building Your Reputation Through Health Testing

Comprehensive health testing does more than produce healthy puppies. It builds your reputation as a responsible breeder who prioritizes genetic health.

Advertise your health testing prominently. List OFA numbers on your website. Share certificates on social media. Join your breed club's health initiatives. Connect with other health-focused breeders.

As enforcement of breeding regulations increases (see our article on the 2026 federal crackdown), health testing demonstrates professionalism. It shows you're invested in the breed's future, not just making quick money.
