Maine Pet Lemon Law: What to Do if You Bought a Sick Dog or Cat

If you just brought home a puppy from a Maine breeder and it starts vomiting or won’t eat three days later, you are not simply out of luck. Pet lemon laws in Maine give buyers of sick dogs and cats specific legal rights, and those rights come with strict deadlines you need to know before you ever call the seller.

This guide walks you through what Maine’s law actually covers, how many days you have to act, and what happens if a breeder or pet shop refuses to cooperate. You’ll also learn which animals and sellers fall outside the law entirely, so you don’t waste time chasing a remedy that doesn’t apply to your situation.

Does Maine Have a Pet Lemon Law

Yes. Maine’s version of a pet lemon law lives in Title 7, Chapter 745 of the Maine Revised Statutes, the chapter governing the sale of dogs and cats, and it has been on the books since the mid-1990s. Consumer advocates and legal researchers typically call this category of statute a “Pet Purchaser Protection Act” or puppy lemon law, and as of 2023, 22 states have enacted pet purchase protection acts.

The American Veterinary Medical Association lists Maine among the states with pet lemon laws, alongside states such as Arizona, California, Connecticut, and New York. Broadly speaking, these laws generally require sellers to offer refunds, exchanges, or reimbursements for veterinary expenses if a pet becomes ill or has a hereditary condition within a specified time frame.

Maine’s statute is narrower than some people expect. It applies only to dogs and cats, it only kicks in when money changes hands, and it puts specific procedural steps on the buyer’s shoulders. Miss a deadline or skip a required notice, and you can lose your remedy even if the animal really was sick at the time of sale.

Which Animals and Sellers Are Covered in Maine

Maine’s pet lemon law covers exactly two species: dogs (Canis lupus familiaris) and cats (Felis catus). Rabbits, birds, reptiles, and other companion animals aren’t part of this chapter, no matter how sick they turn out to be or how much you paid for one.

On the seller side, the law reaches further than you might assume. Animal shelters, kennels, breeding kennels, boarding kennels, and pet shops engaged in buying or selling animals must keep records of the buyer and seller in each transaction for a two-year period, which means even smaller operations are expected to document their sales. If you’re researching how a specific breeding operation is licensed and zoned, the article on kennel zoning laws in Maine covers those requirements in more depth.

Maine also closes a loophole that trips up buyers in other states. Colorado, Maine, Massachusetts, and Pennsylvania extend their underage-puppy sale restrictions to any person, not just licensed dealers — meaning a backyard breeder selling a single litter can still fall under the law’s reach. Specifically, a person may not advertise for sale, sell, or exchange for value more than one cat or dog under six months of age in a 12-month period unless that person holds a valid shelter, kennel, or breeding kennel license, or a vendor’s license. That vendor’s license, once issued, is valid for 90 days, and a person is entitled to one free vendor’s license every 12 months, with a $25 fee for any additional license in that same period. If you’re bringing a dog or cat into Maine from out of state rather than buying locally, separate holding-period rules apply before that animal can be resold or adopted out; the article on pet import laws in Maine explains those requirements. Under Maine’s importation rules, dogs and cats imported for resale or adoption must be retained by the importer for five days if they are six months of age or younger, and 48 hours if they are older, before being offered to a buyer.

If your concern is specifically about a cat you purchased, the broader rules around cat ownership and outdoor access in the state are addressed separately in the guide to outdoor cat laws in Maine.

Reporting Deadlines: Illness vs. Congenital Conditions in Maine

Timing is where most pet lemon law claims succeed or fail. Under Maine’s statute, consumers have 10 days to document health problems existing before purchase, and one year for hereditary or congenital defects. Nationally, these windows vary quite a bit — the amount of time a purchaser has to make a claim ranges from seven to 20 days for illness or injury and 10 days to two years for congenital or hereditary conditions depending on the state — so Maine’s 10-day illness window sits on the shorter end. There’s a separate, faster clock layered on top of that reporting window. The purchaser must notify the seller within two business days of a veterinarian’s diagnosis of a health problem, providing the seller with the veterinarian’s name and phone number and a copy of the vet’s report. In practice, that means the 10-day and one-year windows tell you how long you have to discover the problem, while the two-business-day rule tells you how fast you must act once a vet actually confirms it.

Condition Type	Reporting Window	Documentation Required
Illness present before purchase	10 days from receiving the animal	Vet diagnosis, plus notice to seller within 2 business days
Hereditary or congenital defect	1 year	Veterinary certification that the condition existed before sale
Death linked to a pre-existing condition	As soon as possible after death	Written vet statement that the animal died from a health problem that existed on or before delivery

One quirk worth knowing: the clock for a veterinary certification usually starts the day the animal is sold, though timeframes for hereditary or congenital conditions sometimes start on the animal’s date of birth instead in states with this type of provision. Ask your vet to note both dates on the report so you’re not arguing about which deadline applies.

Pro Tip: Book a veterinary exam within the first few days of bringing your dog or cat home, even if nothing seems wrong yet. A clean bill of health protects you later, and an early diagnosis preserves your right to a refund, exchange, or reimbursement under Maine’s 10-day window.

Your Options If Your Pet Is Sick in Maine

Once a licensed veterinarian confirms your dog or cat had a health problem before you took possession, Maine law gives you more than one path forward. You generally have the right to keep, return, or exchange the animal and be reimbursed for veterinary expenses, rather than being forced into a single fixed remedy.

If you choose the refund route, timing matters again: you must return the animal no later than two business days after receiving a written veterinary statement that the animal is unfit due to a health problem. If your pet died rather than merely getting sick, you must provide the seller with a written veterinary statement indicating the animal died from a health problem that existed on or before you took delivery of it. Maine is unusual in spelling this out — while most Pet Purchaser Protection Acts focus on illness or congenital conditions, some states, like New Hampshire and Maine, make specific provisions for what happens if the animal dies. There’s also a distinct provision for animals with a shortened life expectancy. For an animal with less than one year of life expectancy, as determined by a veterinarian, you may retain the animal and receive a full refund of the original purchase price — though the seller is not required to reimburse veterinary fees under this particular provision. That’s a meaningful trade-off: you keep the pet you’ve likely already bonded with, but you absorb ongoing vet costs yourself. Registration paperwork problems have their own remedy track, separate from illness. If a seller promised pedigree registration but never delivered the documents, the seller must provide the documents necessary for registration at the time of sale or within 90 days. If that deadline passes, you can send a written request via certified mail, and the seller then has 60 days to deliver the documents. Still nothing? You’re entitled to a partial refund of 50% of the purchase price. These choices intersect with broader questions about who legally “owns” a pet once a dispute starts, particularly if you’ve already invested in vet care or grown attached to the animal — a topic covered in more detail in the guide to pet custody laws in Maine.

How to File a Pet Lemon Law Claim in Maine

Acting in the right order, within the right windows, is what separates a successful claim from a frustrating dead end. Here’s the practical sequence:

1. Schedule a veterinary exam immediately. Do this well inside the 10-day illness window or one-year congenital window, since the clock doesn’t pause for scheduling delays.
2. Get a written diagnosis. You need a formal veterinary report, not just a verbal opinion, before you can move forward with any remedy.
3. Notify the seller in writing within two business days of the diagnosis, including the veterinarian’s name, phone number, and a copy of the report, as required under Maine’s purchaser responsibilities statute.
4. Decide on your remedy. Weigh a refund, an exchange, or keeping the animal with veterinary reimbursement, based on which option actually serves your situation.
5. Return the animal within two business days of receiving the veterinarian’s written unfitness statement, if a refund is the remedy you’re pursuing.
6. Save every document. Keep the seller’s written disclosure statement, the sales contract, receipts, and the notice of consumer rights the seller was required to give you at the time of sale.
7. Escalate if the seller refuses. Contact the state agency named in your consumer rights paperwork, or pursue the matter through small claims court if the seller won’t honor the law.

That last step has real teeth built into the statute. The statement of consumer rights you receive at purchase must include the name and phone number of the state agency to contact in the event of a perceived violation of this chapter. If that paperwork went missing, the full text of Chapter 745 and the Animal Legal & Historical Center’s table of pet purchaser protection acts are useful references for confirming exactly what you were owed.

What Maine’s Law Does Not Cover

Knowing the law’s limits saves you from wasted effort. A few common gaps trip up buyers who assume Maine’s pet lemon law works like a general consumer protection statute:

• Animals other than dogs and cats. Backyard poultry, goats, pigs, hedgehogs, and livestock all fall under entirely different Maine statutes. See the separate guides on backyard chicken laws in Maine, goat ownership laws in Maine, hedgehog ownership laws in Maine, and backyard pig laws in Maine for the rules that actually apply to those animals.
• Conditions the seller disclosed before the sale. Maine requires sellers to make oral disclosure of all required medical information to the purchaser prior to purchase. If a health problem was disclosed and you bought the animal anyway, that disclosed condition generally won’t support a claim.
• Problems that develop after you take the animal home. Across states with this type of law, a remedy typically isn’t available if the illness or injury occurred after purchase, if the vet finds intestinal or external parasites, or if the issue was disclosed at the time of sale.
• Free transfers and gifts. Many state statutes, including provisions like Maine’s, apply only to sales of puppies and not to transfers that don’t involve any monetary or other consideration. If you were given a pet rather than paying for it, this law likely won’t apply.
• Nonprofit shelter adoptions, in many cases. Many states exclude non-profit animal shelters or humane societies from the reach of these laws, so an adoption fee paid to a rescue organization may not trigger the same remedies as a commercial purchase.

Livestock owners tracking animals for other regulatory reasons — such as required identification for goats, cattle, or other farm animals — should also check the separate rules described in livestock microchipping laws in Maine, since none of those identification requirements overlap with the dog-and-cat lemon law.

Buying a sick puppy or kitten is stressful enough without also guessing at your legal options. Maine’s law gives you a real, if narrow, path to a refund, exchange, or reimbursement — but only if you get the vet report, notify the seller, and act within the deadlines the statute actually sets. Keep your paperwork, move fast, and you’ll be in a far stronger position than a buyer who waits and hopes the seller does the right thing on their own.
