The safest way to get one of the puppies you have been browsing is to adopt from a shelter or rescue, or to buy from a breeder who lets you meet the mother and shows health clearances on both parents. Then hold firm on three rules: no pickup before eight weeks, no money before a visit or live video call, and a vet exam within days of bringing the dog home. Most bad outcomes, from scams to sick dogs, trace back to skipping one of those.

A puppy is a dog in its first year of life, and buying one raises questions an adult dog does not: legal pickup age, an unfinished vaccine series, and scams built around young dogs. For breed groups, adult and senior dogs, and year-one costs, see our guide to buying a dog.
How Old Should Puppies Be at Pickup? What State Laws Say
Eight weeks is the minimum. When we checked the Animal Legal & Historical Center’s table of state minimum-age laws in October 2026, it counted roughly 28 states plus Washington, D.C. with a rule on selling young puppies, and almost all of them set the line at eight weeks.
Scope varies. In about half of those states the rule covers any seller; in the rest it applies only to pet shops, dealers, or breeders, so a private backyard sale may fall outside it. Where no law applies, eight weeks is still the welfare standard.
- Under 8 weeks: walk away. Early separation is associated with more resource guarding, fear-based behavior, and poor bite inhibition, because littermates and the mother teach a soft mouth.
- 8 to 10 weeks: the normal window for most medium and large breeds.
- 10 to 12 weeks: better for toy breeds, which need special care because they are tiny and prone to low blood sugar when very young.
A seller offering a five-week-old puppy “because it is eating on its own” is uninformed or rushing a sale.
Where to Look: Three Sources That Fit a Young Dog
Shelters and rescues suit most families and lifestyles. Choose a responsible breeder when you need predictable adult size, coat, or temperament.
Shelters and foster rescues. Adoption fees generally run 75 to 400 dollars and include first vaccinations, spay or neuter surgery, a microchip, and a vet check. Foster-based rescues raise litters in family homes, so the foster can tell you which pup barrels into the room and which one hangs back, then match that personality to your household.
Breed rescues. Nearly every recognized dog breed has a volunteer-run national rescue, from Golden Retrievers to the French Bulldog. Young dogs come through less often than adults, so expect a waiting list, but the volunteers love their breed and know its hereditary problems.
Responsible breeders. Ethical programs raise one or two litters a year and ask you as many questions as you ask them. The American Kennel Club (AKC), the largest US purebred registry, flags its Breeder of Merit and Bred with H.E.A.R.T. programs in its Marketplace, but AKC registration alone proves pedigree, not quality.
Top Sources Worth Your Time
Best for adoption: Petfinder nationwide search. The largest pool of shelter and rescue litters in North America, filterable by breed, age, and location. You apply through the listing shelter, which removes most classified-ad scam risk.
Best for local alerts: Adopt a Pet. Email alerts when a new litter posts near you. Search a wider radius than feels reasonable, because young dogs get adopted within days.
Best for registered breeders: AKC Marketplace. Purpose-bred litters, with prices commonly in the low thousands. A listing is not a quality guarantee, so vet the breeder yourself.
Best for spotting a bad seller: the Humane Society of the United States. A breeder research hub, the annual Horrible Hundred report on problem sellers, and a tip line for reporting a suspected mill.
Vetting a Breeder: Health Clearances You Can Check Yourself
A good breeder hands you registration numbers you can look up, not a promise. The Orthopedic Foundation for Animals (OFA), the nonprofit that runs the main US registry of canine test results, publishes hip, elbow, eye, cardiac, and DNA results by registered name. Its Canine Health Information Center (CHIC) program assigns a number to dogs that completed the tests their breed club recommends.
The catch: OFA will not certify hips or elbows until a dog is at least 24 months old; younger dogs get only a preliminary rating. If the sire and dam are both under two, they cannot have final hip clearances, whatever the listing says.
Questions to Ask Before a Deposit
- Can I meet the mother and see where the litter is raised? A refusal is your answer.
- What are the OFA or CHIC numbers for the sire and dam?
- How many litters has the female had, and at what ages?
- Which vaccines and deworming happen before pickup, and by which vet?
- Will you take the dog back at any age if the placement fails?
You learn as much from what they ask about your home, work hours, and other pets. A breeder who screens buyers is showing you how they care for their dogs.
Puppy Scams and Mill Red Flags (FTC and BBB Guidance)
The classic scam is adorable puppies that do not exist. A fake seller posts stolen photos at a low price, takes a deposit, then invents fees for shipping crates, insurance, or vaccines until the buyer stops paying. A 2017 Better Business Bureau (BBB) study estimated that at least 80 percent of sponsored search ads for pets may be fraudulent.
The Federal Trade Commission (FTC) is blunt about the clearest sign: only scammers insist on payment by gift card, payment app, cryptocurrency, or a wire service such as Western Union or MoneyGram, because that money is hard to get back. Other signs to stop on:
- The seller will not allow a visit or even a live video call.
- A reverse image search finds the same cute photos in older ads.
- A purebred is offered free or far under the usual price.
- New fees appear after the deposit.
- Five or more breeds are always available, shipped by air, with no mother on site.
Craigslist and Facebook Marketplace both prohibit animal sales, and listings that slip through are a known channel for fraud and commercially bred dogs. The American Society for the Prevention of Cruelty to Animals (ASPCA) estimates that roughly 10,000 puppy mills operate in the United States; its shelter and adoption resources are a better starting point. California, Maryland, New York, and Illinois restrict retail sale of commercially raised dogs. If you were scammed, report it at ReportFraud.ftc.gov and to BBB Scam Tracker, and call your bank or payment app the same day.
Paperwork and Guarantees to Collect at Pickup
Leave with written records of every vaccine (product and date), deworming dates, the microchip number, a recent wellness exam, and a signed contract. Return terms are where sources differ most:
| Source | Return policy | Written guarantee | Practical note |
|---|---|---|---|
| Municipal shelter | Usually accepts returns, fee rarely refunded | Rare, as-is placement | Spay or neuter usually included |
| Nonprofit rescue | Return required by most adoption contracts | Varies, ask for it | The foster knows the temperament |
| Breed rescue | Return to the group expected for life | Varies, ask for it | Known breed issues disclosed |
| Responsible breeder | Lifetime return clause is standard | Common, terms vary by source | Read it before the deposit |
| Broker or storefront | Often none | Short window, narrow terms | Walk away |
One gotcha: a guarantee that requires you to return the dog for a refund is a swap clause, not consumer protection. Ask for coverage of a named condition, in dollars, for a stated period. Many guarantees also lapse unless your own vet examines the puppy within a few days, so book that appointment before pickup.
First Vaccines and Vet Visits (AAHA Schedule)
Core vaccines protect against distemper, adenovirus, and parvovirus. The American Animal Hospital Association (AAHA) canine vaccination guidelines call for at least three doses of a combination vaccine between 6 and 16 weeks of age, spaced 2 to 4 weeks apart. A dog that leaves at eight weeks has had one dose at most.
| Age | Who usually handles it | What to expect |
|---|---|---|
| 6 to 8 weeks | Breeder’s or shelter’s vet | First combination dose, deworming |
| Within days of pickup | Your vet | Wellness exam, records review |
| 10 to 12 weeks | Your vet | Next combination dose |
| 14 to 16 weeks or later | Your vet | Final dose in the series; rabies as state law requires |
| About one year later | Your vet | Booster to complete the core series |
Rabies timing is set by state or local law. Lifestyle vaccines such as leptospirosis, Bordetella (kennel cough), and Lyme are chosen with your vet based on where the dog will live and go. The American Veterinary Society of Animal Behavior (AVSAB) says classes can begin at 7 to 8 weeks, once the puppy has had a first vaccine set at least 7 days earlier and a first deworming, because the first three months are the prime window for socialization.
First-Week Setup for New Puppies
Prepare the house before the new puppy arrives, and expect night waking, accidents, and chewing in the first week.
- A crate with a divider. Buy the adult size and block off the back so the young dog has room only to stand, turn, and lie down.
- A baby gate or exercise pen. One small, puppy-proofed area with cords and shoes out of reach beats chasing a dog through the whole house.
- Feed the same food the breeder or shelter used for the first week, then switch gradually if you want a different brand.
- Chew toys for baby teeth. Teething runs roughly from three to six months, and a dog with nothing legal to chew picks your furniture.
- Collar, ID tag, and microchip registration in your name, not the seller’s.
- A potty schedule. Start to train on day one: go out after waking, eating, and play, and skip dog parks until your vet says the vaccine series is far enough along.
Keep the first days quiet, however excited the kids are. A happy, confident adult starts with a calm first week: introduce family members one at a time, and save short, fun visits from new people until the puppy has settled.
The fastest safe way to bring home puppies is to work these steps in order, starting this week, and to budget for the vet visits above. Food, vaccines, and supplies usually cost more in year one than the dog did; our Blue Buffalo food breakdown and Taste of the Wild comparison cover feeding.
- Search both rescue platforms by ZIP code and switch on intake alerts.
- If a specific breed matters, contact its national rescue, then look up any breeder’s sire and dam in the OFA database.
- Never send money before you have seen the mother, the whelping space, and the paperwork in person or on live video.
- Book a vet exam for the first few days after pickup, at eight weeks or older.
FAQ: Buying and Adopting Puppies
How much should you pay from a legitimate source?
Shelter and rescue adoption fees generally run 75 to 400 dollars and include the first round of veterinary work. Breeder prices vary by breed, commonly landing in the low thousands. A price far under the breed average is the most reliable warning sign.
Is it legal to sell a dog younger than eight weeks?
In roughly 28 states plus Washington, D.C., some form of it is not, and most of those laws set the minimum at eight weeks. Some cover any seller, others only pet shops, dealers, or breeders. Where no law applies, eight weeks remains the welfare standard.
Is adopting better than buying from a breeder?
For most households, yes. Shelters and rescues are full of healthy young dogs, purebreds included, and the fee funds more rescue work. A registered breeder is the better route when you need predictable adult size or a hypoallergenic dog breed because someone at home has a dog allergy.
When can a new dog go to the park or meet other dogs?
Structured classes with vaccinated classmates can start at 7 to 8 weeks, a week after the first vaccine set, per AVSAB guidance. Dog parks and unknown dogs should wait until your vet says the core series is far enough along, which usually means near the end of the series.
Can you finance the purchase?
Financing exists, and it is a warning sign in itself. Point-of-sale loans are pushed hard by brokers and storefronts, and the total after interest can approach double the sticker price. Some were written as leases, a practice several states have banned. If the decision hinges on a payment plan, wait, save, or adopt.
