Health Testing for Dog Breeders
The complete guide to understanding OFA certifications, genetic screening, and what every responsible breeder must test – so you can find a truly healthy puppy.
Not all breeders are created equal. The single biggest difference between a responsible, ethical breeder and a backyard breeder or puppy mill is health testing. A breeder who claims their dogs are "healthy" or "vet checked" without providing official certifications is hiding something. True health testing goes far beyond a basic veterinary exam.
This guide walks you through every major health test reputable breeders perform, how to read OFA/PennHIP results, and the exact questions you must ask before buying a puppy. Armed with this knowledge, you will avoid heartache and thousands in veterinary bills later. Start by understanding what responsible breeders do differently – how to find a reputable dog breeder is the first step.
Why Health Testing Matters
Genetic diseases and hereditary conditions are rampant in purebred dogs. Hip dysplasia, elbow dysplasia, progressive retinal atrophy (PRA), degenerative myelopathy (DM), heart disease, and patellar luxation are just a few of the preventable conditions that ethical breeders screen for. Without testing, you are gambling on your puppy's future health.
Hard truth: Over 70% of purebred dogs are affected by at least one hereditary condition, according to OFA statistics. Responsible breeders reduce that risk dramatically by only breeding dogs that pass health screenings. Backyard breeders skip testing to save money – and you pay the price later.
The cost of treating hip dysplasia can exceed $5,000 per hip. Eye disorders may require lifelong medication. Genetic diseases like Von Willebrand's disease or MDR1 drug sensitivity can be fatal. When you buy from a breeder who health tests, you are not just paying for a puppy – you are paying for transparency and reduced risk.

Essential Health Tests Explained
Responsible breeders follow recommendations from the Orthopedic Foundation for Animals (OFA) and their breed's parent club. Here are the most common tests you should look for, depending on the breed.
Hip Dysplasia (OFA / PennHIP)
X-rays evaluated by specialists. OFA rates Excellent, Good, Fair (acceptable), Borderline, or Dysplastic. PennHIP measures laxity and predicts arthritis risk. Required for most medium to giant breeds.
OFA: $350–$500 | PennHIP: $400–$600Elbow Dysplasia
Elbow radiographs graded by OFA as Normal or Dysplastic (I, II, III). Common in Labs, Rottweilers, Bernese Mountain Dogs, and German Shepherds.
$200–$350Eye Certification (CERF/CAER)
Annual exam by a veterinary ophthalmologist to detect cataracts, PRA, retinal dysplasia, and other heritable eye diseases. Many breeds require yearly clearance.
$60–$150 per yearCardiac Exam
Auscultation by a cardiologist or echocardiogram (ultrasound). Screens for subaortic stenosis, mitral valve disease, and cardiomyopathy. Required for Boxers, Dobermans, Cavaliers, and Newfoundlands.
$250–$600Patellar Luxation
Physical manipulation of kneecaps to check for looseness. Common in small and toy breeds like Chihuahuas, Yorkies, Pomeranians, and Bichons.
$50–$150 (part of OFA exam)Thyroid Testing
Blood panel for autoimmune thyroiditis. Essential for breeds prone to hypothyroidism: Golden Retrievers, Dobermans, Setters, and many hounds.
$150–$300Genetic DNA Testing for Breed-Specific Diseases
DNA tests identify whether a dog carries mutations for specific inherited diseases. Unlike hip X-rays, genetic tests can be done at any age and do not require sedation. Major laboratories include Embark, Paw Print Genetics, and UC Davis. However, remember that genetic tests do not replace physical evaluations – a dog can be genetically clear for hip dysplasia but still develop it due to polygenic factors.
- PRA (Progressive Retinal Atrophy) – causes blindness. Tests available for over 100 breeds.
- Degenerative Myelopathy (DM) – ALS-like spinal cord disease. Affects German Shepherds, Boxers, Pembroke Corgis.
- Von Willebrand's Disease (vWD) – bleeding disorder common in Dobermans and Scottish Terriers.
- MDR1 Drug Sensitivity – ivermectin toxicity risk. Herding breeds (Collies, Aussies, Shelties) must be tested.
- Exercise-Induced Collapse (EIC) – Labs, Curly Coated Retrievers, Cocker Spaniels.
- Congenital Deafness – linked to merle and piebald genes. BAER testing required for Dalmatians, Border Collies, Aussies.
Important: A "clear" genetic result means the dog does not have the mutation. But some diseases are not single-gene – polygenic traits require OFA-type evaluations. Always ask the breeder for both DNA test results AND physical screenings.

Breed-Specific Health Testing Recommendations
Different breeds have different risk profiles. Below are common requirements based on the OFA CHIC program (Canine Health Information Center). Responsible breeders pursue CHIC certification by completing all recommended tests for their breed.
| Breed Group / Example | Required Tests (Typical) | CHIC Required? |
|---|---|---|
| Golden Retrievers | Hips, Elbows, Eyes (annual), Cardiac, PRA1/PRA2, Ichthyosis, DM | Yes (7 tests) |
| German Shepherds | Hips, Elbows, DM, Hemophilia A, Eyes, Cardiac | Yes (6 tests) |
| French Bulldogs | Hips, Patellas, Eyes, Cardiac, Trachea (BOAS), DM, Cystinuria | Yes (8 tests) |
| Labrador Retrievers | Hips, Elbows, Eyes, EIC, CNM, PRA, DM, Heart | Yes (8 tests) |
| Doberman Pinschers | Hips, Eyes, Cardiac (Echo/Holter), vWD, DM, Thyroid | Yes (6-7 tests) |
| Cavalier King Charles Spaniels | Cardiac (Echo), Eyes, Patellas, DM, Episodic Falling, Syringomyelia MRI | Yes (6 tests) |
Check the OFA website for your specific breed's recommended tests. Many popular dog breeds have extensive health screening requirements – responsible breeders follow them religiously.
How to Verify a Breeder's Health Testing Claims
Breeders can easily lie or exaggerate. Verbal claims like "my vet says she's healthy" mean nothing. You must see official documentation.
Do not accept "our dogs are tested" without proof. You have the right to see the results before committing to a puppy. For a complete list of questions to ask a dog breeder, include: "May I see the OFA certificates and genetic test reports for both parents?"
Red Flags: When Breeders Skip Testing
🚩 Walk away immediately if the breeder says:
- "We don't need health tests because our dogs are healthy."
- "The vet checked them – that's enough."
- "We test for everything (but can't show you certificates)."
- "The stud dog is OFA tested but we lost the paperwork."
- "We only breed for temperament, not health testing."
- "Testing is too expensive."
Compare puppy mill vs reputable breeder to see how lack of health testing is a hallmark of commercial breeding operations. Also learn red flags of a bad dog breeder before you visit any litter.
Costs of Health Testing – Why Responsible Breeders Charge More
Health testing is expensive for breeders. A full CHIC panel for one dog can cost $800–$1,500, sometimes repeated annually (eyes). Genetic testing adds $150–$300 per dog. Ethical breeders also perform brucellosis testing and possibly progesterone, semen analysis, and C-sections. This is why well-bred puppies cost $2,000–$5,000+ while backyard breeders sell for $500–$1,200. You are paying for generations of health clearances.
Estimated breeder expenses per breeding pair (health tests only):
- Hip/Elbow radiographs + OFA review: $500–$800
- Eye CERF exam (renewed annually): $100
- Cardiac echo/auscultation: $250–$600
- Genetic panel (Embark for Breeders): $150–$200
- Thyroid & other bloodwork: $150–$250
- Total per dog: often $1,200–$2,000 before any breeding occurs
