Sick puppy rights

The Massachusetts pet lemon law

The protection people call the pet lemon law lives in MDAR's pet shop regulation rather than in the General Laws, and it covers less ground than its nickname suggests. Here is what it requires, whom it binds, the timing, and what a breeder purchase leaves out. Treat this as general information, not legal advice; for a sick puppy and a dispute with a seller, talk to MDAR or a consumer lawyer.

Where the law lives

The rule is 330 CMR 12.05(5), and it binds licensed pet shops

The authority behind it is chapter 129, section 39A, which requires anyone in the business of operating a pet shop to hold a state license and lets the department write rules for those businesses. MDAR's rules are 330 CMR 12.00, Licensing and Operation of Pet Shops. A Class A license is the one that covers dogs and cats, and section 12.05(5) puts the refund duty on 'each Class A Licensee.' We found no separate lemon law section in chapter 129 itself, so when you see the phrase, this regulation is what it points to.

The regulation defines a pet shop broadly, as a place where animals are kept for wholesale or retail sale, import, export, barter, exchange or gift, and a sale includes giving an animal away. But section 39A says it does not apply to people 'selling, exchanging or otherwise transferring the offspring of their personally owned animals.' As the text reads, a breeder selling puppies from their own dogs is outside pet shop licensing and so outside this warranty. Licensed rescues come under a different regulation, 330 CMR 30.00, with disclosure rules of its own.

  • Statutory authority: chapter 129, section 39A
  • The refund rule: 330 CMR 12.05(5)
  • Who it binds: Class A licensees, the shops licensed to sell dogs and cats
  • Outside it, as written: breeders selling offspring of their own dogs

The timeline

Fourteen days to see a vet, then three days to bring the animal back

The refund has two conditions. First, within 14 calendar days of the sale, the buyer has the dog or cat examined by a veterinarian of the buyer's choice, and the exam 'indicates the dog or cat is diseased or has a congenital disorder.' Second, the buyer presents the animal to the shop within three days of the exam, with the vet's written statement saying so and proof of sale. If the animal dies while under veterinary care, the attending vet's statement documenting the death can be presented instead of the body.

The shop must then refund the full purchase price promptly, or provide a substitute animal if both the shop and the customer consent, and any euthanasia decision after a refund is made in consultation with the shop. The regulation sets one window for both disease and congenital disorders, the 14 days; we found no longer window for an inherited problem that appears later. Under section 12.10, MDAR may deny, revoke or suspend the license of a shop that intentionally prevents a customer from using the warranty.

    At the sale: take the animal record and the 14-day warranty notice, and sign the acknowledgment

  2. 02

    Within 14 calendar days: a full exam by a vet you choose

  3. 03

    If the vet finds disease or a congenital disorder, get the finding in writing

  4. 04

    Within three days of that exam: go back to the shop with the animal, the statement and proof of sale

  5. 05

    Ask for the full refund, or accept a substitute only if you want one

Paperwork at the sale

The shop owes you records, a warranty notice and a recent health certificate

Section 12.05(4) requires the shop to give each customer, at the time of sale, a copy of the animal's individual animal record and, for a dog or cat, a notice of the 14-day warranty; the customer signs a statement acknowledging both. That record covers vaccinations, medical treatment and medications, the animal's source and its identification. Section 12.05(3) bars a Class A shop from selling a dog or cat without a vet's health certificate dated no more than seven calendar days before the sale, and from acquiring or selling any dog or cat younger than eight weeks.

One discrepancy is worth knowing. MDAR's printable warranty and records form, a one-page sheet we read in an archived copy, quotes an earlier numbering of the rule and gives two business days after the exam, while the current regulation text gives three days. Until MDAR reconciles them, the cautious course is to act within the shorter period, and to ask MDAR's Division of Animal Health which one it applies.

  • The individual animal record, with vaccines and treatments
  • A written notice of the 14-day warranty, signed for
  • A vet's health certificate dated within seven days of the sale
  • No dog or cat younger than eight weeks

Breeders and private sellers

Buying from a breeder: what still applies, and why the contract matters

A few statutory rules reach beyond pet shops. Section 39G of chapter 129 says a dog or cat sold by 'a commercial establishment, pet shop, firm or corporation' must come with a health record showing the date and type of each vaccine. The same section bars any seller, including an individual, from selling a surgically devocalized dog or cat without written notice before the purchase agreement; without that notice the agreement is void, and the violation is an unfair or deceptive practice under chapter 93A. A dog brought into Massachusetts must also travel with an official health certificate.

For a private breeder's puppy, most of the rest is contract. Read the written agreement before paying: what health warranty it offers, if any, for how long, what the remedy is, whether that is a refund, a replacement or vet costs, and whether it requires you to return the puppy. If a dispute arises, a consumer lawyer is the right person to ask; this page cannot tell you whether a particular sale broke the law.

The first two weeks

Use the 14 days well: an early vet visit and a careful start at home

The 14-day window rewards a fast vet appointment, so book it before the puppy comes home. Bring every page the shop or breeder handed over, including the vaccination record, because your vet builds the rest of the series on it and the dates matter again for licensing and daycare. Massachusetts requires rabies vaccination by 6 months of age, and a dog over 6 months must be licensed with the clerk of the city or town where it lives, in Gloucester the City Clerk at 9 Dale Ave.

Puppies can start learning long before they can join a playgroup. Tiny Tails Puppy School is for pups 8 to 16 weeks old, and AKC S.T.A.R. Puppy runs from 8 weeks to 6 months; both are taught fear- and force-free. Daycare comes once the vaccine series is done: we need Rabies, DHPP and Bordetella and a city license on file, and a free evaluation on a weekday morning between 6:30 and 9:30 AM at 210 Eastern Ave.

Asked and answered

Questions people ask about this

Short, complete answers you can act on today. More in the full FAQ.

Does the Massachusetts pet lemon law apply to breeders?
As written, the refund rule binds Class A pet shop licensees, and chapter 129, section 39A excludes people selling the offspring of their personally owned animals from pet shop licensing. A breeder selling puppies from their own dogs is therefore outside the pet shop warranty, and your protection rests mainly on the written contract. Ask a consumer lawyer about a specific purchase.
How long do I have to return a sick puppy to a pet shop?
The vet exam must happen within 14 calendar days of the sale, and you must present the puppy to the shop within three days of that exam, with the vet's written statement and proof of sale. MDAR's printable warranty form gives two business days instead, so act within the shorter time to be safe.
Do I have to give the puppy back to get a refund?
The refund is tied to presenting the dog or cat to the shop with the vet's statement and proof of sale, and a substitute animal is offered only when both sides consent. If the animal died under veterinary care, the attending vet's statement about the death takes the place of returning the body. Ask the shop and MDAR before assuming any other arrangement.
Can a pet shop sell a puppy younger than eight weeks?
No. Section 12.05(3) bars a Class A licensee from acquiring, selling or offering for sale any dog or cat younger than eight weeks, and chapter 129, section 39G bars commercial sellers from importing dogs or cats under eight weeks for sale in Massachusetts. The shop must also hold a vet's health certificate dated within seven days of the sale.
Can a pet shop sell a puppy that is already sick?
No. Section 12.05(1) bars a licensee from selling or offering any animal that tests positive for or shows signs of listed conditions, including contagious diseases such as parvovirus, distemper and kennel cough, parasitism affecting its health, and fractures, lameness or congenital abnormalities affecting its general health. The 14-day warranty covers problems found after the sale.
