Questions to Ask a Breeder

Choosing a breeder can feel a little like online dating. Everyone looks great in photos, everyone says the “right” things, and it is hard to know who is truly doing the work behind the scenes.
As a veterinary assistant in Frisco, Texas, I have seen both ends of this decision: families who bring home a thriving, well-socialized puppy and families who walk into a clinic weeks later with preventable parasites, serious congenital issues, or a puppy who is terrified of the world.
The good news is that you can protect yourself and your future dog with a short list of proven questions. A quality breeder will welcome them. A risky breeder will dodge them.
One quick note before we dive in: even responsible breeders can see an occasional health issue pop up. The difference is that they are transparent, they learn from it, and they take responsibility for what they produce.

What a responsible breeder looks like
Before the questions, it helps to know what you are looking for. A responsible breeder typically:
- Breeds with a purpose (health, temperament, structure, working ability, or well-defined companion goals), not just “cute puppies.”
- Health screens the parents with breed-appropriate tests and shares proof. This often includes orthopedic or eye exams (as appropriate) and may include DNA testing, but “DNA only” is rarely the whole picture.
- Raises puppies in the home with early handling, gentle socialization, and age-appropriate enrichment.
- Uses a contract and offers lifetime take-back support if you cannot keep the dog.
- Asks you questions too because they care where their puppies go.
Now let’s talk about the questions that uncover these qualities fast.
Questions to ask a breeder
1) “What health testing do you do on the parents, and can I see the results?”
This is the single most important question. “Vet checked” is not the same as “health tested.” You want breed-appropriate screening protocols, typically guided by parent club recommendations and listed on OFA (Orthopedic Foundation for Animals). For some breeds, PennHIP may be used for hips. DNA testing can be helpful, but it does not replace physical exams and imaging when those are recommended.
- Strong answer sounds like: “We follow the OFA recommendations for this breed. We have OFA hips (or PennHIP), elbows (if recommended), annual eye exams, a cardiac exam (if recommended), and DNA testing for X and Y. Here are the links and copies.”
- Red flags: “Our dogs are healthy, we have never had problems,” or “The vet says they are fine,” without documentation.
2) “Which conditions are you actively trying to prevent in this breed or mix?”
Every breed and mix has common risks. A trustworthy breeder will name them plainly and explain how they reduce risk through screening, pairing choices, and puppy-raising practices.
- Strong sign: They talk about issues that are truly relevant to their dogs, such as hips, patellas, eyes, heart, allergies, airway concerns (for flatter-faced dogs), and temperament concerns specific to their lines.
- Red flag: “Hybrids never have health problems.” Mixed-breed dogs can be wonderful, but they are not automatically immune.
3) “Can I meet the puppy’s mom, and where are the puppies raised day-to-day?”
Meeting the mom (dam) tells you a lot about temperament, stress level, and how the breeder manages their dogs. Seeing the environment tells you about sanitation, enrichment, and early socialization.
- Strong answer: “Yes. Puppies are raised in our home. Here is where they sleep, play, and start potty training.”
- Worth a follow-up: If they will not show you where puppies are raised, ask why. Some breeders limit visits for biosecurity, but they should offer a live video call, detailed updates, and real transparency.
4) “What is your socialization plan from birth to go-home day?”
This is where great breeders shine. Early experiences shape how a dog handles noise, strangers, handling, grooming, and new environments.
- Look for: gentle handling from day 1, exposure to household sounds, safe novel surfaces, crate introductions, positive car rides, early grooming practice, and age-appropriate time away from littermates.
- Red flag: “They are raised with our kids so they are socialized.” That helps, but it is not a plan.
5) “How do you match puppies to homes?”
Ethical breeders do not let families pick solely by color or “first deposit.” They evaluate temperament and help you choose the best fit.
- Strong answer: “We do temperament evaluations and observe daily. Then we match based on your lifestyle, energy level, and goals.”
- Red flag: “Pick any puppy you want from the photos today.”
6) “What are the puppies eating, and what do you recommend long-term?”
Nutrition impacts growth, gut health, coat quality, and long-term wellness. A solid breeder should be able to explain why they feed what they feed and how they transition puppies.
- Good sign: clear feeding schedule, measured portions, transition instructions, and a discussion of large-breed puppy growth if relevant.
- Note: If you want to feed homemade or fresh food, a good breeder will discuss it thoughtfully and encourage you to do it safely with veterinary guidance.
7) “What vaccines and deworming have been done, and can I see the records?”
Puppies commonly carry intestinal parasites, even when they look perfectly fine. You want a written record of deworming dates, products used, and vaccinations given.
- Expect: a veterinarian record or signed documentation, plus guidance on the next due dates.
- Ask specifically: “Have the puppies had a fecal test?” A fecal exam can help catch parasites like giardia and coccidia that are common in puppies. It is helpful but not perfect because some parasites shed intermittently, so also ask what the breeder does if a puppy develops diarrhea.
8) “At what age do puppies go home?”
In many places, eight weeks is the commonly recommended minimum age for puppies to go home, and many laws also require 8 weeks or older. Some excellent breeders keep puppies longer, often around 9 to 10 weeks, depending on the breed and the individual puppy. (Toy breeds and certain working or performance-focused lines may stay a bit longer.)
- Red flag: sending puppies home at 6 to 7 weeks. Early separation is associated with a higher risk of bite inhibition issues, anxiety, and difficulty with dog-to-dog communication.
- Tip: Check your local laws and ask your veterinarian what they recommend for your area and breed.
9) “Do you provide a written contract and health guarantee? What exactly does it cover?”
Contracts protect the puppy and the buyer. A quality contract is clear about spay and neuter expectations, return policy, and health guarantees for genetic conditions.
- Look for: a realistic health guarantee tied to documented testing and veterinary evaluation timelines.
- Read the fine print: Some guarantees require a vet exam within a set number of days, specific documentation, or specific remedies (refund, replacement puppy, partial refund). Make sure you understand what happens if a serious issue is found.
- Avoid: vague promises with no written terms.
10) “If I cannot keep this dog at any point, what happens?”
This question is a big divider. Responsible breeders nearly always have a lifetime return policy. They do not want their dogs ending up in shelters or rehomed through strangers.
- Best answer: “The dog comes back to us, no questions asked.”
- Red flag: “Once you buy the puppy, it’s your problem.”
11) “How many litters do you have per year, and how many adult dogs do you keep?”
This helps you understand scale. More volume does not automatically mean poor quality, but high volume without transparency is risky.
- Good sign: they can explain their program size, how dogs are housed, and how they prevent burnout in breeding females.
- Red flags: constant availability of many different mixes, pressure to buy fast, or unwillingness to discuss adult dog living conditions.
12) “Can you share references from past puppy families and your veterinarian?”
References add accountability. A reputable breeder usually has repeat buyers, positive long-term updates, and a veterinary relationship.
- Tip: When you talk to references, ask what the breeder was like after the sale. Did they answer questions? Did they help during challenges?
13) “Can you share the parents’ registered names or pedigrees, and how long you’ve been breeding this line?”
This is about traceability and accountability. Even for mixes, you should be able to confirm the identity of both parents and learn what the breeder is selecting for over time.
- Good sign: they can tell you why they chose that pairing and what they have produced in prior litters (temperament, health outcomes, working ability, companion traits).
- Quick reality check: AKC registration can be a useful piece of paperwork, but it is not proof of quality by itself. It should never replace health testing and solid puppy raising.
14) “How do you avoid doubling up on genetic issues?”
You do not need a genetics degree to ask this. You are listening for intentional decision-making. Some breeders track COI (coefficient of inbreeding) or use pedigree tools to avoid stacking the same problems generation after generation.
- Good sign: they can explain how they choose pairings to reduce known risks, not just produce a certain look.
- Red flag: they seem offended by the question or dismiss genetics entirely.
Quick red flags
- They cannot or will not provide proof of health screening and testing.
- Puppies are always available, or there are many litters at once with little detail.
- They focus heavily on “rare colors” or “teacup” sizing as the main value.
- They will meet you in a parking lot or ship immediately with minimal screening.
- Puppies appear dirty, under-socialized, fearful, or lethargic.
- They do not ask you any questions about your home, schedule, or experience.
If you see multiple red flags, it is okay to walk away. It is much easier to wait for the right breeder than to treat preventable illness and manage long-term behavioral fallout.
If you are unsure
Ask for verification
If they claim OFA or PennHIP testing, ask for the registered names and numbers so you can verify results. Ethical breeders are used to this.
Schedule a video call
If an in-person visit is not possible, request a live walkthrough showing the puppies, mom, and the main living area. Live is important. Pre-recorded videos can be carefully curated.
Loop in your veterinarian
Before you put down a deposit, ask your veterinarian what health tests they would expect for that breed or mix. After you bring your puppy home, schedule a new-puppy exam within 48 to 72 hours and bring all records.
Consider rescue
If you are flexible on age or you are open to a wonderful adult dog, breed-specific rescues and reputable shelters can be a great fit. Many dogs in rescue are already past the intense puppy stage and may come with foster notes on temperament.
Simple checklist
When you are talking to a breeder, keep this short list handy:
- Proof of health testing for both parents (breed-appropriate, not just “vet checked”)
- Clear explanation of common health risks and how they reduce them
- Puppies raised in a clean, enriching environment
- Socialization plan (not just “they are around kids”)
- Written vaccine and deworming records, ideally including fecal testing (and a plan if GI issues occur)
- Go-home age aligns with common best practices and local laws (often 8+ weeks; sometimes longer)
- Contract, health guarantee details, and lifetime return policy
- Breeder matches puppy temperament to your lifestyle
If a breeder meets these standards and communicates with patience and transparency, you are likely in very good hands.
