Spay Neuter Contract: Limited Registration, Deadlines and Proof

A spay neuter contract is the agreement in which a pet buyer promises to spay or neuter the puppy by a set age, send the breeder a vet's written proof, and never breed it. The puppy usually goes on limited registration, and the contract states what a breach costs the buyer, such as lost health guarantees or an agreed fee.

A spay neuter contract is the agreement a pet buyer signs when you sell a puppy on limited registration: it sets the age by which the puppy must be spayed or neutered, the proof you need, and what happens if the dog is bred anyway. It usually goes out with your sales and health guarantee agreement, before or at go-home.

The wording is the easy part. The hard calls are the ones a template leaves to you: 12 months or later for a big male, what counts as proof, whether a pet can ever earn breeding rights, and what you'll do if a buyer breeds the dog. Here's how to make those calls, fit the agreement with your other contracts, and run it in BreederBuddy. If you only need starting wording, see our puppy contract templates.

What a spay neuter contract covers

A complete spay neuter contract covers the pet-only sale, registration, the deadline, proof, breach and return to breeder:

• Companion pet only. No breeding rights, and the buyer agrees the dog won't be bred, on purpose or by accident.
• Limited registration. The puppy is registered, but its litters can't be.
• The deadline. The age by which the buyer has the puppy spayed or neutered.
• Proof. What the buyer sends you, from whom, and by when.
• Registration papers. Whether you hold them until the proof arrives.
• Breach. What the buyer forfeits or owes, and whether you can take the dog back.
• Return to breeder. If they can't keep the dog, it comes back to you, not to a shelter or broker.
• General terms. Which state's law applies, and that the document is the whole agreement.

Limited registration, full registration and breeding rights

Limited registration lets a pet carry papers without letting its puppies be registered, and with the AKC only the litter's owner can lift it later.

To change a dog from limited to full, the litter owner files the AKC's Application to Revoke Limited Status, with a processing fee. Other registries set their own rules, so match the clause to yours.

If a pet could ever become a breeding dog, put the conditions in the agreement: health clearances, any title, your approval of each mating, any upgrade price and who files the paperwork. Mind the timing. OFA certifies hips and elbows only at 24 months or older, so a dog with a 12-month deadline can't finish those clearances before it. If an upgrade is possible, add that the deadline pauses once you both agree in writing.

Choosing the spay and neuter deadline

Set the deadline by the puppy's expected adult size and sex, because veterinary guidance treats small and large dogs differently. The American Animal Hospital Association suggests neutering small-breed males (under 45 pounds as adults) at about six months and spaying small-breed females before their first heat, at five to six months. For large breeds it suggests neutering males after growth stops, usually at 9 to 15 months, and spaying females within a 5 to 15 month window the vet narrows for the dog. A UC Davis study of 35 breeds found that joint and cancer risks after neutering varied by breed, and in most breeds the age of neutering didn't change the risk. It leaves the decision to the owner and their veterinarian.

What that means for the contract:

• One age rarely fits every litter. A 12-month deadline sits inside the large-breed window but well past the five to six months suggested for small-breed females.
• Leave room for the buyer's vet. Allow a later date if their vet recommends it in writing before the deadline and you agree.
• Line it up with your guarantee. Some breeders who guarantee hips ask buyers not to alter before a set age, and say so in both documents.

Proof, breaches and written changes

Ask for a vet's written proof, and set a consequence you're prepared to enforce. It should come from a licensed veterinarian, give the date and the dog's microchip number, and arrive within a set time after the surgery (the BreederBuddy starter says 30 days). A vet's certificate or medical record does it. A buyer's word doesn't.

Give the buyer a reason to send it. A common lever is holding the registration papers until proof arrives, which the starter allows. Some breeders take a refundable alteration deposit instead.

For a breach, the starter says the buyer forfeits the health guarantees and pays liquidated damages in an amount you set, and the breeder may reclaim the dog. Whether a court enforces those terms depends on your state's law and the wording. Generally, an agreed amount stands a better chance in court when it's a reasonable estimate of your real loss rather than a punishment. Have an attorney in your state review these clauses, and write only terms you'd stand behind.

Plans change after go-home: a vet recommends waiting, a pet turns out to be breeding quality. The starter says it's the entire agreement, so side promises made before signing don't count, and a change agreed later by text is easy to dispute. Put every change in a short addendum you both sign.

How it fits with your sales and health guarantee agreement

A spay/neuter agreement covers what the buyer may do with the dog, beside the deposit agreement that holds the spot and the sales and health guarantee agreement that covers the sale.

• Say it once, or say it the same way. BreederBuddy's Puppy Sales & Health Guarantee starter already has a short Spay / Neuter & Registration section (alter by 12 months, proof from a vet, breeding voids the guarantees). If you also send the standalone agreement, make the deadline and remedies match, or cut that section.
• Guardian homes are the reverse. In BreederBuddy's Guardian Home Agreement starter you keep ownership and breeding rights, then spay or neuter the dog at your expense when the terms are done. See how a guardian home program works.
• Decide pet or breeding home early. Your puppy application questions are where buyers tell you their plans, and a deposit holds their spot while you decide (more in puppy deposit tracking).

Step 1: Start from the spay/neuter template

BreederBuddy includes a Spay/Neuter & Limited Registration Agreement among its six starter contracts, ready to edit and save as your own.

1. In the left menu under Sales, click Contracts, then Add New Contract.

1. On the Spay/Neuter & Limited Registration card, click Use this template.
2. Check the Contract Title, then edit the Terms & Conditions (seven sections, from Companion Pet Only to General).
3. Under Dog Fields to Include, the starter ticks name, date of birth, sex, breed, microchip and the first registration number (shown with your registry's label).
4. Leave Require email verification for this contract ticked, so the buyer enters a code from their email before they can view or sign.
5. Click Save.

Two edits are worth making first. Swap the fixed "twelve (12) months" for a custom placeholder such as ${spay_neuter_age}, so BreederBuddy asks for the age at each send and one template fits every litter. Then add your vet extension line and any path to full registration; the starter has neither.

Step 2: Send it for one buyer and one puppy

Each agreement goes to one buyer for one puppy, with the puppy's details pulled from its profile.

1. Open the template and click Send Contract to Customer.
2. Pick the buyer under Customer and the puppy under Dog. The starter fills in the puppy's breed, so it won't send without a puppy picked.
3. Under Contract Variables, the kennel name, buyer's name and breed are prefilled (you can override them). Type in Breeding Penalty.
4. Click Save. The buyer gets an email with a secure link and a six-digit verification code. If they aren't yet the puppy's owner, you're asked Set Owner? and can fix it in one click.

The agreement prints your letterhead, both parties, and a Subject Dog block with the puppy's photo and the fields you ticked. Blank fields print as N/A, so fill in the microchip and registration number first.

You can also send from the buyer's record (Financial & Contracts, then Contract Requests, then Send Contract) or from a litter's Journey tab. To let a buyer read it first, tick Send as a preview only (no signature required).

Step 3: E-signing and the signed PDF

The buyer signs from the email link after entering their code, and the signed PDF is saved to both the buyer and the puppy. They open the link (or Review & Sign in their buyer portal), enter the code under Verify Your Email, type their name in Your Name, sign in Sign Below with a finger or mouse (or click Use Typed Signature), and click Sign & Submit. No account or password. A lost code shows on the template's Requests tab, so you can read it to them.

The signed PDF carries both signatures (your name fills the Breeder / Seller line from your account) and an electronic signature record: a reference number, the signer's name and email, the time, their IP address and device. It's stored:

• on the puppy's Attachments tab
• on the buyer's record, under Contract Requests and in their attachments
• on the template's Requests tab, with Download PDF
• in the buyer's portal, under Contracts

You get an email when it's signed, plus a push notification if you use the BreederBuddy Android app, and the buyer gets an email with a link to their copy. Editing the template later doesn't change agreements already sent. For a change after signing, write the addendum as its own short template and send it the same way. More on keeping buyers organized in buyer management.

Step 4: Track the deadline until proof arrives

Record the contract on the puppy, put the deadline on your calendar, and tag the puppy until the vet's proof is in.

1. On the puppy, click Edit Details and set Fertility to Contract to Spay/Neuter.
2. In Settings, open Preferences, find Health estimates and set Spay/neuter estimate (months) to your usual contract age. It's one number for every puppy (1 to 36, 10 by default).
3. The puppy's Health tab shows a Spay / Neuter Estimate box with that date while its Type is Puppy. Once the date passes, the box reads Ready for spay/neuter procedure until Fertility says Spayed / Neutered.
4. For the exact contract date, click New Event on the Calendar, date it on the deadline, link it to the puppy with Associate With, and tick Email Reminder? to get an email yourself.
5. Tag the puppy (for example "Owes spay proof"). Filtering your Dogs list by that tag under More filters shows every puppy still owing proof.
6. When the vet's proof arrives, upload it to the puppy's Attachments tab, set Fertility to Spayed / Neutered and remove the tag.

The estimate is marked veterinary reference only; the date in the signed agreement is the one that counts.
