How to sell a dog in Connecticut
A dog bill of sale records the sale of a puppy or adult dog with the breed, sex, date of birth, color, microchip and registration, plus the price and any health guarantee. Breeders use it for every puppy; private sellers use it so the new owner has proof of ownership for vets, registries and licensing.
Seller steps
- Confirm you hold clear title. If a lender is on the title, get the lien release before you list it.
- Agree on the price and fill in the Connecticut dog bill of sale above with the buyer. Record the serial number.
- Both parties sign and each keeps a copy. Connecticut does not require a notary.
- Hand over any registration papers, manuals, receipts or health records that go with the dog.
- Hand over the dog and keep your signed copy of the bill of sale for your records.
Buyer steps
- Check the description against the dog itself before you sign.
- Keep the signed bill of sale with your records; it is your proof of ownership and purchase price.
- Transfer any registration papers and update the microchip or brand records in your name.
Before you sign
- Record the microchip number and update the chip registry after the sale.
- List vaccinations given and the next due dates.
- If there is a health guarantee or a spay/neuter requirement, write it in the terms.
- Breeders: keep a signed copy with the litter records.
Why a bill of sale matters for a dog
- Proof of ownership for licensing, vet records and microchip registration.
- Registries like the AKC require the breeder's signature to transfer.
- Records the health guarantee, or the lack of one, in writing.
- Settles a dispute if the dog is lost or claimed by someone else.

Does the buyer need to file a dog bill of sale in Connecticut?+
No. Dogs and puppies are not titled or registered with the state, so there is nothing to file. The signed bill of sale is the ownership record; each party keeps a copy.
Is a dog bill of sale legally binding?+

Most breeders include one, often 48 to 72 hours for a vet check and one to two years for genetic conditions. Write the terms in the extra terms field; without them the sale is as-is.
