When you're buying a puppy or kitten, understanding breed-specific health risks isn't optional—it's essential for making an informed choice. Different breeds are predisposed to different genetic conditions, and a responsible breeder should be able to discuss these openly and provide health testing documentation. Asking the right questions protects your wallet, your timeline, and most importantly, the animal's wellbeing.
Why Breed Health Matters Before Purchase
Every breed has genetic vulnerabilities. Golden Retrievers face hip dysplasia and certain cancers; French Bulldogs struggle with breathing issues and spinal problems; Persian cats commonly develop kidney disease. These aren't just minor inconveniences—they can mean $3,000–$10,000 in veterinary bills within the first few years, plus emotional strain.
A breeder's willingness to discuss these issues transparently signals integrity. Breeders who dodge health questions or claim their line "never has problems" are red flags. Legitimate breeders have done their homework, conducted genetic testing, and maintain honest records.
Core Health Questions to Ask Your Breeder
Start with these direct questions before committing to a purchase:
- "What genetic health issues are common in this breed, and what testing have you done on the parents?" Listen for specifics: hip and elbow scores (OFA or PennHIP), cardiac evaluations, eye certifications (CERF), or DNA tests for breed-specific markers. Generic answers suggest they haven't invested in proper screening.
- "Can you provide health test results in writing?" Reputable breeders will email you documentation—not just verbal reassurance. Ask for the parent dog's test dates and scores, not just a casual mention.
- "What is your policy if the puppy develops a genetic health condition within the first year or later?" Some breeders offer partial refunds; others guarantee replacement offspring. This varies widely, but clarity matters. Expect this clause in a formal contract ($1,500–$3,500 puppy might come with a 1–2 year genetic health guarantee; higher-end breeders sometimes offer lifetime support).
- "How long do dogs from your line typically live, and what health issues have you seen in past litters?" Honest breeders can cite real lifespan data and describe health challenges they've observed. Evasiveness here is a warning sign.
- "Are you a member of a breed club, and do you follow breed health guidelines?" Membership in organizations like the American Kennel Club Breed Club or the breed's national health foundation suggests they're staying current on genetic research.
Red Flags and What They Mean
If a breeder won't provide written health test results, insists the breed has no health issues, or hasn't health-tested parents, walk away. Similarly, if they pressure you to decide quickly or avoid direct answers about genetic conditions, they're prioritizing sales over animal welfare.
Legitimate breeders typically have waiting lists of 3–12 months. They ask you detailed questions about your home, lifestyle, and expectations. They're not desperate to sell; they're selective about placement.
What to Do With the Information
Once you have health details, research what these conditions actually mean. A dog with borderline hip dysplasia might live normally with monitoring; one with severe dysplasia could need $5,000+ surgery. Talk to your veterinarian about the specific breed and the breeder's test results. Many vets can interpret OFA or genetic screening scores.
Also ask for references—breeders should provide contact info for previous buyers. Call three or four past customers and ask directly: "Did your dog develop any of the genetic issues the breeder mentioned?" and "How transparent was the breeder about ongoing health?"
Finding Vetted Breeders
Use breed club websites and health registries (like the Orthopedic Foundation for Animals) to cross-reference a breeder's testing. Platforms like Mercoly help you compare and find trusted pet breeders in one place, so you can review credentials and reviews side-by-side.
Never buy from pet stores or unvetted online sellers. Puppy mills cut corners on health testing entirely, which is why their dogs often face expensive, preventable conditions.
Frequently Asked Questions
Q: Should I ask a breeder about their breeding dog's parents' health? Yes—grandparent health history reveals longer-term genetic patterns. Ask specifically about health issues that appeared across multiple generations.
Q: What does "OFA certified" or "PennHIP scored" actually mean? Both are hip dysplasia screening methods; OFA is more common and evaluates hip quality on a scale (Good, Fair, Poor), while PennHIP provides a numerical score. Request the actual scores, not just a verbal confirmation they were tested.
Q: Can I negotiate price based on health test results? Occasionally, yes—especially if a dog is a planned breeding dog or slightly older. However, genuine health testing increases a breeder's costs, so expect to pay $200–$500 more for a health-tested litter versus an untested one.
