If you're thinking about bringing home a new puppy, it's completely normal to feel overwhelmed. Which breed is right for you? How do you tell a responsible breeder apart from a pet store with unclear sourcing - or worse, a puppy mill? What if the puppy develops health issues nobody warned you about?

These worries are valid.

Finding a responsible breeder is essential for ensuring a healthy puppy that fits your life and your home.

The good news is that with the right checks, you can feel confident making this decision. This guide walks you through 10 practical things every buyer should verify before saying yes - written with Singapore in mind but useful anywhere.

By the end, you'll have a clear checklist you can use on calls, WhatsApp chats, and in-person visits.

Check 1: Is the Breeder Properly Licensed and Legal?

A responsible breeder always complies with local laws. In Singapore, that means holding a valid AVS (Animal & Veterinary Service) licence for commercial dog breeding. Since April 2022, AVS licensing conditions require breeders to retire breeding dogs by age six, limit each dog to one litter per year, and avoid inbreeding.

Ask directly: "Are you licensed?" Request the licence number and a photo. When you visit, the kennel name should match what's on the licence, and the premises should have adequate space, proper ventilation, and clean flooring. Any legitimate business will be happy to share this.

Contrast this with unlicensed backyard breeders who insist on meeting only in a carpark or outside of their location or refuse to show facilities.

Check 2: Health Testing, Vaccinations, and Written Vet Records

There's a big difference between a breeder saying "the puppy is health checked" and actually providing evidence. Verbal assurances like "there's no such thing as health problems in this line" mean nothing without documentation.

Before you pay any deposit, ask to see:

• A veterinary health certificate
• Vaccination card or AVS health booklet (covering distemper, parvovirus, adenovirus, parainfluenza, leptospirosis)
• Deworming schedule and parasite prevention records
• Microchip number
• Any laboratory blood test reports (liver, kidney, organ function)

Health testing helps identify inherited conditions early, and breeders should perform breed-specific health tests for puppies. A trustworthy veterinarian will have signed off on these records. Ethical breeders are comfortable sending scanned copies with the puppy's microchip number clearly visible.

Pretty Pets Kennel provides a concrete example here: their puppies are blood-tested with certified laboratory reports, vaccinated, microchipped, and sent home with an AVS health and vaccination booklet - giving puppy buyers real peace of mind rather than just words.

Check 3: Hereditary Health Screening of Parents

Genetic diseases can affect many purebred dog breeds, and most hereditary conditions don't show symptoms in a young puppy. That's why screening the breeding dogs before mating matters more than examining the pups alone. Ethical breeders require health testing for their breeding stock and prioritise breed preservation and health in every decision.

Ask the breeder which hereditary tests they've run on the parents. For Toy Poodles and Maltipoos, that might include DNA panels for progressive retinal atrophy (PRA) and patellar luxation grading. Health screenings can include hip X-rays and thyroid blood tests for larger breeds.

Genetic tests can determine if a dog is a disease carrier - two carrier parents can produce affected offspring even if both appear perfectly healthy.

Purebred dogs have specific breed standards defined by parent clubs, and organisations like the Orthopedic Foundation for Animals maintain health testing databases that outline health testing requirements by breed. Reputable breeders keep files of results for each breeding dog and will share them.

Dog breeds vary significantly in size and temperament, so the specific tests differ. For example - Cavapoos need cardiac screening, Corgis need hip and eye checks. A serious breeder can explain exactly why they chose specific tests for their chosen breed.

The red flag? A breeder who says "my vet said they look fine" but can't name exact tests, dates, or results. Breeders should aim to produce healthy, stable offspring meeting the breed standard, and the likelihood of achieving that drops sharply without proper genetic testing.

Check 4: Where and How the Puppies Are Raised

How pups are raised in their first 8–12 weeks shapes their temperament, confidence, and ability to settle in quickly - especially in an HDB flat or condo. A trustworthy breeder welcomes in-person visits to see the living conditions of the dogs. Visit the breeder's facility to assess cleanliness and puppy health.

You should see clean, well-lit areas with no strong ammonia smell, separate sleeping and toilet zones, safe toys, and signs that pups have been handled by people. The facilities should meet licensing requirements for sanitation and biosecurity, including separate isolation areas for sick animals.

Positive signs: pups that are curious but not terrified, comfortable around humans, appropriate weight, and a mum who appears relaxed. Warning signs: the breeder refuses any view of the premises, only meets at a carpark, or keeps puppies in tiny wire-floored cages. If someone won't let you see where the dogs live, that's a sign to walk away.

Check 5: Meet the Parents (or at Least the Mother)

You should be able to see where the dogs live and meet the mother / parents of the litter. The dam's temperament, size, coat, and movement give you the clearest preview of how your adult dog may turn out. Look for a mother who is friendly or calm, in appropriate body condition, with clear eyes and a healthy coat.

In some breeding programs, the father may not live on-site. That may be normal - but reputable breeders will have photos, videos, and health documentation for the sire. A responsible breeder uses the mother's temperament to help match puppies to suitable homes, making sure each family gets a good match - particularly important for first time dog owners or those with young children.

Red flags include a refusal to let you see where the dogs live or meet the parents, a claim that the mother "isn't here" without explanation, or showing a female who clearly isn't bonded with the litter. Breeders should interview potential puppy buyers thoroughly, and a detailed interview process indicates a breeder's commitment to placing puppies in the right forever homes.

Check 6: Early Socialisation and Daily Handling

Good dog breeding isn't only about genetics. Ethical breeders socialise puppies in a healthy environment before they leave at 8–12 weeks. Puppies should not go home until they are at least eight weeks old to learn socialisation skills from their littermates and mother.

Ask specific questions: "What do you do to socialise your puppies each week?" "Are they used to crates or playpens?" "Have they heard household noises and experienced grooming?" Look for practices like gentle daily handling, exposure to different surfaces and sounds, and early toilet routines.

This is especially important for apartments. Well-socialised pups adapt faster to lifts, corridor sounds, and grooming salons - the success of their transition depends heavily on what happens before they reach you. Some breeders will deliberately plan socialisation and daily routines from birth to raise behaviourally stable dogs that settle in quickly.

Check 7: Breeder Transparency, Communication Style, and Proof

The right breeder is open, not pushy, and patient with questions. They expect you to ask a lot before deciding. Good breeders typically have waiting lists of repeat customers - that's a positive sign, not a reason to rush you.

Look for clear answers in writing, willingness to send photos and videos of the actual litter, and no pressure to pay a deposit "today only." Reputable breeders ask prospective owners many questions about their home, lifestyle, and experience. Breeders should provide references from past puppy buyers and have a track record of positive outcomes - you can often find these through reviews and testimonials. Local breed clubs often curate listings of reputable breeders to help you in your search as well.

A person interested in buying should also expect honest breed advice. Good breeders discuss both pros and cons - grooming needs, shedding, energy levels - rather than overselling.

Warning signs: vague answers about dog breeding practices, changing stories about where puppies come from, or insisting "no other breeder will give you this deal."

Check 8: Contracts, Documentation, and Ownership Papers

A reputable breeder uses a clear written contract to protect both the buyer and the puppy. This isn't just a form - it's a sign of professionalism.

A basic contract should cover:

• Puppy details: breed or cross, colour, sex, date of birth, microchip number
• Parents' information and any registration papers
• Price paid in local currency
• Health guarantees
• Return or rehoming clauses

Reputable breeders tend to provide a return-to-breeder clause in contracts, ensuring their dogs always have a safety net. Ethical breeders will clearly state if a puppy is sold as a pet and may include spay or neuter guidance to prevent irresponsible breeding later.

You should receive physical or digital copies of vaccination records, microchip registration, and the local registration health booklet. Compare this with low-transparency sellers who only give a receipt from a pet store with no breeder name, or who sell puppies "as is" with no written health statement. The sale should always come with proper documentation - anything less should make you pause.

Check 9: Lifetime Aftercare Support and Guidance

The relationship shouldn't end the moment you carry your puppy home. Ideally, you should receive a lifetime of support and guidance from the breeder after adoption. This is what separates breeders who genuinely care about their puppies' forever homes from those focused purely on the sale.

Meaningful aftercare looks like WhatsApp support for questions, follow-up messages after the first few days, and willingness to advise on diet, grooming, training, and health concerns alongside your vet. Many ethical breeders also include starter kits and sometimes complimentary grooming to help pets settle in.

Red flags? A breeder who disappears after the sale, blocks messages, or tells you "go ask your vet, not my problem."

Check 10: Red Flags That Suggest Puppy Mills or Irresponsible Sellers

Avoiding bad sources is just as important as finding the right breeder. The breeding industry still includes sellers - including some pet store setups and online listings - where profit comes before welfare.

Clear red flags to watch for:

• Very large number of different breeds available at once (dogs, cats, kittens - everything "in stock")
• No proof of where puppies were born or raised
• Cash-only transactions or "today-only" discounts
• Willingness to hand over a puppy under eight weeks old
• Only stock photos, recycled videos, or sellers who can't answer basic breed questions
• Claims like "farm-sourced from champion lines" without any documentation

Ethical breeders do not sell puppies to pet stores. If something feels off during your search, there's a better way: walk away and keep looking for reputable breeders, or consider adopting from a shelter or rescue where homeless animals deserve loving homes. A rushed purchase almost never ends well.

Singapore-Specific Considerations: Housing, Lifestyle, and Where to Buy

Choosing an ethical breeder also means factoring in licensing requirements, and lifestyle realities. A responsible breeder will guide you away from unsuitable breeds even if it means losing a sale - that's a sign you've found a good place to buy.

The community of dog owners has several options: buying from a pet store, an unlicensed home-based breeder, an overseas import, or an locally-licensed breeder. Each carries different risks. For many prospective owners, working with a transparent, locally-licensed breeder who offers guidance and aftercare provides more peace of mind than anonymous online listings where you can't verify anything.

If you're unsure about how much owning a dog really costs, prepare your questions first. Join forums, talk to current owners, and prioritise breeders who feel patient - not pushy - and who clearly care where their puppies end up.

Quick Checklist: 10 Questions to Ask Any Dog Breeder Before You Say Yes

Save this list and use it when speaking with any breeder:

• "Can you share your local licence number and a photo of the licence?"
• "Where were these puppies born and raised? Can I see the area (in person or video)?"
• "Can I meet or see the mother of the litter?"
• "What health testing have you done on the parents and puppies? Can I see the reports?"
• "Can you send me a photo of the vaccination card/local licensing booklet with the puppy's microchip number?"
• "How do you socialise your puppies before they go home?"
• "What kind of written contract and health guarantees do you provide?"
• "What support will I have after I bring the puppy home?"
• "At what age can the puppy go home?" (Expect 8–12 weeks, depending on breed.)
• "If my situation changes, can the dog be returned to you or rehomed with your help?"

Take your time. Trust your instincts. A good breeder will never rush you - and if you're unsure where to start, breeders like Pretty Pets Kennel are happy to guide you through every step of the decision.
