To transfer dog ownership, sign a written agreement with the new owner covering the sale or gift, hand over the dog’s veterinary and registration records, and update the microchip registry, the dog license, and any breed registration to the new owner’s name. Done properly the whole thing takes a few days and costs very little. Skip a step and you invite disputes, vet-office confusion, or a lost dog that traces back to the wrong person.
Check Your Original Paperwork Before Anything Else
Find the papers from when you first got the dog. If the dog came from a rescue or shelter, your adoption agreement almost certainly requires you to return the animal to that organization rather than rehome it privately. Those clauses exist so the rescue can screen the next home, and they’re treated as enforceable contracts in most jurisdictions. Ignoring one can expose you to a breach-of-contract claim or a demand that the dog come back.
Call the rescue before you arrange anything. Some will work with you if you’ve already found a good home. Others will insist on handling the placement themselves. If you bought the dog from a breeder or private seller and there’s no return clause, you’re free to proceed.
Gather the Records the New Owner Will Need
Pull everything together before transfer day. The new owner needs:
- Complete veterinary records: vaccination history, spay or neuter documentation, and notes on any ongoing conditions or allergies. If you’ve used more than one vet, request records from each.
- The microchip number and the name of the registry (PetLink, 24PetWatch, HomeAgain, AVID, and others). This is usually on your original adoption paperwork or an old vet bill. Any vet can scan the dog and identify the chip and registry if you can’t find it.
- A current rabies certificate. Most states require one before a dog can be licensed.
- Proof of ownership: original adoption papers, a prior bill of sale, or a registration certificate.
- Your current dog license number and the name of the municipality that issued it.
Missing vet records can be requested from your vet’s office. Microchip registries keep records you can look up online. Don’t wait until handoff day to discover gaps.
Write a Transfer Agreement
A written agreement is the single most important document in the process. It doesn’t require a lawyer, but it does need enough specificity that no one can later claim confusion. Treat it as a bill of sale for the dog.
What to Put in It
Start with the full legal names, addresses, and phone numbers of both parties. Describe the dog so it can’t be confused with any other animal: name, breed, sex, approximate date of birth, color, distinguishing markings, and the microchip number. “Brown mixed breed” won’t hold up if anything is ever disputed.
The core language transfers all ownership rights and responsibilities from you to the new owner, effective on a specific date. If money is changing hands, state the exact price. If the dog is a gift, say so directly. Ambiguity about payment is one of the most common sources of arguments after the fact.
Include a line confirming that you are the legal owner and have the authority to transfer the animal. Both parties sign and date, and each keeps a copy. Witnessing or notarizing the signatures adds protection but isn’t legally required in most situations.
Disclose Health Issues, and Sell As-Is
If the dog has known health problems, put them in the agreement. That protects you from later claims that you concealed something. For a private transfer between individuals, state that the dog is being transferred “as is” and that you make no guarantees about future health. Without that language, the new owner could argue you implicitly promised the dog was healthy.
Update the Microchip Registration
This is the step people forget, and it’s the one that matters most if the dog ever goes missing. If the chip still points to you six months later, the new owner has a real problem.
Procedures depend on the registry. Generally, the current registered owner initiates the transfer through the registry’s website or by phone, providing the new owner’s name and contact information. Some registries then send the new owner a confirmation to accept.
Fees vary. PetLink charges a one-time $29.99 transfer fee, though pets adopted from organizations with PetLink professional accounts may qualify for a free transfer.1PetLink. Does It Cost Money to Transfer Ownership? 24PetWatch does not charge a transfer fee. For any other registry, contact them directly; procedures and pricing aren’t uniform across companies.
After the paperwork is submitted, the new owner should call the registry or log into their account and confirm that a lookup of the chip number now returns their information, not yours.
Get a New Dog License
Licenses are issued by your municipality or county and typically don’t transfer between owners. Notify your local animal control office that you no longer own the dog. The new owner applies for a fresh license in their own jurisdiction.
A new license application usually requires proof of current rabies vaccination, the microchip number, and proof of spay or neuter status, which often qualifies for a reduced fee. Annual license fees range roughly from $7 to $50 across the country, with unaltered dogs generally paying more. Contact your local animal control office for exact requirements, since they vary widely.
Transfer Breed Registry Records
If the dog is registered with a breed organization like the American Kennel Club, the registration transfers separately. The AKC requires the previous owner to sign the back of the dog’s registration certificate, and the new owner submits it to the AKC to update the record.2American Kennel Club.

What the New Owner Should Do in the First Week
Don’t just file the paperwork. Schedule a veterinary appointment within the first week or two and bring the full medical history so your vet can build a patient file and flag any upcoming vaccinations or treatments. It also gives you a baseline health assessment under your own vet’s care.
Follow up on every registration. Call the microchip registry to confirm your contact information is on file. Check with local animal control that your license application has been processed. Both are easy to let slide, and both are exactly what matters when a dog gets loose or a dispute surfaces months later.

Taxes if Money Changes Hands
Giving a dog away for free carries no tax consequences. Selling one does, at least in principle. The IRS treats pets as personal property. If you sell for more than you originally paid, the profit is a capital gain you’re supposed to report. In practice this mostly affects breeders and people selling high-value dogs, not someone rehoming a family pet. If you sell for less than you paid, you can’t deduct the loss, because losses on personal-use property aren’t deductible.5Internal Revenue Service. Topic No. 409, Capital Gains and Losses
Some states also treat pet sales as taxable transactions subject to sales tax, since animals are tangible personal property. Whether that reaches a one-time private sale or only commercial breeders varies by state. For a substantial sale price, a short call to a tax professional is worth it.
