Puppy Lemon Laws by State: Deadlines, Remedies and What to Do

Puppy lemon laws by state differ more than most buyers expect. Pennsylvania gives a veterinarian 10 days to certify that a puppy was sick at the time of sale, others allow a full year for a genetic defect, and several only cover pet stores, not the breeder down the road. This guide compares the laws in Florida, Pennsylvania, California, New Jersey and Arizona, explains where Ohio and Washington buyers stand, and walks through what to do, step by step, if your new puppy gets sick.

What is a puppy lemon law?

A puppy lemon law, formally a pet purchaser protection act, is a state law that lets you return, exchange or keep a puppy and recover some veterinary costs when a vet certifies, within a set number of days, that it was sick or had a congenital defect when you bought it. Each state sets its own deadlines and covered sellers.

The Animal Legal & Historical Center at Michigan State University College of Law keeps a Table of Pet Purchaser Protection Acts. Its 2023 edition counts 22 states with such a law (checked October 17, 2026). Three details decide whether one helps you: who the seller is, how fast you act, and whether the problem was disclosed in writing at the sale.

Puppy lemon laws by state: deadlines and remedies

The table covers five states whose current statute text was reviewed on October 17, 2026. The illness column is the time a vet has to certify an illness that existed at the sale. The congenital column covers inherited or birth defects. Depending on the state, the clock starts on the purchase date or the day you take the puppy home.

State and law	Who it covers	Illness	Congenital or hereditary defect	Your remedy options
Florida, Fla. Stat. § 828.29	Pet dealers selling more than three litters or 30 dogs or cats a year, including breeders who sell directly to buyers	30 days after the sale	1 year after the sale	Refund or exchange plus vet exam and emergency costs, or keep the puppy and recover reasonable treatment costs
Pennsylvania, 73 P.S. § 201-9.3	Sellers whose kennel or pet shop is licensed by the state Department of Agriculture or the USDA; nonprofit kennels excluded	10 days after purchase	30 days after purchase	Refund (not including sales tax), replacement, or keep the puppy with vet fees up to the purchase price
California, Health & Safety Code § 122070	Breeders who sold or gave away three or more litters or 20 or more dogs in the past 12 months; a parallel act covers retail pet dealers	15 days after you take possession	1 year after you take possession	Refund or exchange plus vet fees up to the price, or keep the dog with vet fees up to 150% of the price
New Jersey, N.J.S.A. 56:8-95	Pet shops selling dogs and cats	14 days after purchase	180 days after purchase	Refund, exchange, or keep the animal, plus vet fees up to twice the purchase price
Arizona, A.R.S. § 44-1799.05	Pet stores only	15 days after you take possession	60 days after you take possession	Refund, or exchange or keep the puppy with vet fees up to the purchase price

Florida shows why the review date matters. The 2026 Florida Statutes allow 30 days for an illness, while the 2023 animallaw.info table lists 14.

Coverage matters as much as deadlines. Arizona's law applies only to pet stores. New Jersey's statute covers pet shops, and the state handles other pet dealers through separate rules not summarized here. California and Florida reach breeders above a size threshold, and Pennsylvania reaches licensed kennels.

Which other states have a puppy lemon law?

According to the animallaw.info table (2023 edition, checked October 17, 2026), the other 17 states with a pet purchaser protection act are Arkansas, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Minnesota, Nebraska, Nevada, New Hampshire, New York, Oregon, Rhode Island, South Carolina, Vermont and Virginia.

Their deadlines, remedies and covered sellers vary. The table notes, for example, that Delaware and Rhode Island exempt sellers of fewer than 20 dogs or three litters a year. Because the table predates any amendment passed since 2023, read your state's current statute before you count days.

Does Ohio have a puppy lemon law?

Ohio does not appear in the animallaw.info table of 22 states with a pet purchaser protection act (checked October 17, 2026), and this review did not confirm a separate Ohio refund statute. Ohio buyers should treat the written sales contract and the seller's health guarantee as their main protection, and ask the Ohio Attorney General's office about current law.

Is there a puppy lemon law in Washington State?

Washington is not in the animallaw.info table either (checked October 17, 2026). Its animal welfare chapter, RCW 16.52, sets care and sales rules, not buyer refunds. It caps anyone at 50 intact dogs over six months old; under RCW 16.52.360 a retail pet store may not sell dogs unless it sold them before July 25, 2021 and meets sourcing rules.

This matters on All Puppies, where six of the seven breeders listed on October 17, 2026 are in Washington: Yakima, Woodinville, Sammamish, Port Angeles, Pasco and Moses Lake. For a Washington purchase, the breeder's written health guarantee is your main written protection, so read it before you pay.

What to do if your puppy gets sick after you buy it

Act within days, not weeks. Get a veterinary exam right away, ask the vet for a written certification, notify the seller in writing before your state's notice deadline, follow the treatment plan, and keep every record. Missing a deadline or skipping prescribed treatment can cost you the remedy, even when the puppy was sick at the sale.

1. Book a vet exam immediately. The windows are short: 10 days in Pennsylvania, 14 in New Jersey and 15 in Arizona and California. Florida's required buyer notice tells new owners to have the pet seen by a veterinarian immediately.
2. Ask for a written certification. California and Arizona, for example, require your name and address, the exam dates, the breed and age, the findings, a statement that the dog was unfit for sale, and an itemized bill if you are claiming vet costs.
3. Notify the seller in writing, fast. Pennsylvania gives you 2 business days after the certification. Arizona and California give 5 days after the diagnosis. Florida gives 7 business days after the vet's determination, then 3 business days to hand over the written certificate. Include the vet's name and phone number.
4. Follow the treatment plan. Arizona, California and Pennsylvania can deny a remedy if you do not carry out the treatment the diagnosing vet prescribed. California makes an exception when the treatment plus the diagnosis would cost more than the purchase price.
5. Choose your remedy in writing. In all five states in the table, the buyer, not the seller, chooses between the refund, exchange and keep-the-puppy options.
6. Keep the paper trail. Save the contract, health certificate, receipts, messages and every vet invoice. Here is which documents to expect when you buy a puppy and how to read vaccination records.
7. If the seller disputes the claim. Florida, Arizona, Pennsylvania and New Jersey let the seller have the animal examined by a vet of its choosing. If you still cannot agree, Florida, Arizona and Pennsylvania point to court, including small claims in Florida. New Jersey sends contested pet shop claims to a hearing before its Division of Consumer Affairs.

How puppy lemon laws relate to your health guarantee

A state lemon law is a legal floor; a breeder's health guarantee is a contract. Where a law applies, the guarantee can add protection, and some states block attempts to waive the statute: New Jersey treats a pet shop's effort to secure a waiver as a deceptive practice. Where no law applies, the guarantee is often your only written remedy.

• Written disclosures can narrow your rights. In Florida, Pennsylvania and California, a condition the seller disclosed in writing at the sale, with the required veterinary paperwork, can rule out a later claim for that same condition. Read every disclosure before you sign.
• Compare the contract with the table. Check the illness and genetic windows, the remedy, who chooses it, and any conditions attached. These health guarantee questions help you spot weak terms.
• Deposits are a separate issue. The laws reviewed here deal with a puppy's health after the sale. What happens to money paid before pickup is set by your agreement, as explained in this guide to puppy deposit refunds.

Frequently asked questions

Do puppy lemon laws cover hobby breeders?

Sometimes. California's breeder act starts at three litters or 20 dogs in 12 months, and Florida's at more than three litters or 30 dogs or cats a year. Pennsylvania covers licensed kennels, and Arizona only pet stores. A small home breeder below those lines may fall outside the statute, which makes the written contract more important.

Do worms or fleas count as an illness?

Usually not on their own. Florida, Pennsylvania and California exclude intestinal or external parasites unless the puppy is clinically ill because of them, and Arizona says a parasite finding is not grounds for declaring a dog unfit. Illnesses and injuries that begin after you take the puppy home are excluded in all four.

What happens if the puppy dies?

Arizona and California presume an illness existed at the sale if the animal dies within 15 days of delivery, and New Jersey treats a death within 14 days, other than by accident or injury, as proof the animal was unfit. You still need a vet's written statement, but Arizona and California do not require you to return the body.

Can I get a refund if registration papers never arrive?

In Pennsylvania, yes. If a seller represented the dog as registrable and does not deliver the paperwork within 120 days, without a written extension for an imported dog, you can return the dog for a full refund, not including sales tax, or keep it and receive 50% of the price back.

Before you pay, ask for the health guarantee in writing and compare it with your state's law. You can browse puppies from breeders on All Puppies, ask each one for the contract and health records, and use these steps to verify a puppy seller before you commit.
