A dog is not a thing – it is a family member, a companion and for many people a life partner. Yet, from a legal perspective, an animal is still a subject of civil law, just like a car or real estate. That is why it pays to have a well-drafted dog purchase contract that clearly sets out the rights and obligations of both parties when buying a dog. This will prevent many problems – whether it is unexpected illnesses, missing pedigree or disputes over money.

Quick summary

  • A dog purchase agreement protects both the buyer and seller, especially in later disputes over the health, origin or price of the dog.
  • Although a dog is not a thing under the Civil Code, the rules on the purchase of a thing apply mutatis mutandis to a dog.
  • In the case of a purchase from an entrepreneurial breeder, the rules of consumer purchase and liability for defects may apply.
  • The contract should contain precise identification of the dog, including its chip, vaccinations, health status and any pedigree certificate.
  • Without a written contract, it is difficult to prove later what was promised and under what conditions the dog was delivered.

Why a dog purchase contract should be a matter of course

Many people decide to buy a dog out of excitement and under the influence of emotions. They see a cute puppy, talk to the breeder or seller and in their euphoria take their new pet home – often without a single piece of paper. However, this approach can backfire on the new dog owners later. All it takes is for illness to set in, for the puppy to stop matching what was promised, or for the breeder to refuse to take responsibility.

From a legal point of view, the purchase of a dog is also an ordinary purchase relationship under the Civil Code. And if anything goes wrong, the case will be dealt with under this law. According to Section 494 of the Civil Code, a living animal has a special meaning and value already as a living creature endowed with senses, and the provisions on things apply mutatis mutandis to a living animal only to the extent that this does not contradict its nature. In practice, a written contract for a dog serves as important evidence – it allows to prove what was agreed, what the condition of the dog was when it was taken over and what rights the buyer has.

What should be included in a dog purchase contract?

A good dog purchase contract should be clear, concise and specific. It usually contains the following points:

Identification of the parties to the contract: Write down the full name, address, date of birth or registration number (if the breeder is a business). Include contact details.

Description of the dog: The dog must be accurately identified in the contract:

  • breed, sex, date of birth,
  • colour, coat markings,
  • chip or tattoo number,
  • pedigree number (for dogs with PP),
  • vaccination and deworming information,
  • data related to the central register of dogs,
  • information on the parents, if applicable.

Price and payment terms. E.g.: “The buyer shall pay the price of 25 000 CZK by transfer to the seller’s account [account number] on the day of delivery of the puppy at the latest.”

Date of handover and transfer of ownership: Indicate the date of delivery of the dog, which is particularly important for any liability for defects.

Health assurance: The seller should declare that the dog is healthy at the time of sale, free from any signs of genetic defects, vaccinated and dewormed.

Liability for defects: Specify how you will deal with any latent defects, i.e. diseases or birth defects that were not apparent on acceptance.

Special Provisions: some breeders require additional conditions:

  • prohibition of resale of the dog,
  • a ban on breeding,
  • the obligation to neuter,
  • the right of redemption if the buyer does not take care of the dog.

However, such provisions may not be legally enforceable if they restrict the ownership rights of the new owner. On the contrary, in some cases they could even be considered invalid. Indeed, many of them can be seen more as recommendations and it is up to the goodwill of the buyer to comply with them.

What if I take a dog from a shelter or rescue?

Although adopting a dog from a shelter is usually not a classic purchase contract in the true sense of the word, it is also a legally very important contractual document to sign. This is usually an adoption contract, which aims to protect both the dog and the new owner. The contract for the dog should contain basic information about the shelter and the adopter, a description of the dog, its health, vaccinations and information about any special needs of the animal. The shelter will often include the adopter’s obligations, such as the obligation to provide proper care for the dog, the prohibition of chain ownership or the prohibition of re-selling the dog.

In some cases, the contract may also include an agreement to control the conditions of the breeding or a provision to return the dog to the shelter if the adopter is unable to care for it. Although some of these requirements are legally difficult to enforce, they can be important in resolving future disputes and demonstrating goodwill on both sides.

Is it possible to claim the dog?

Yes. Although a dog is a living being, the law states that the purchase process is similar to other goods. For a purchase from a breeder or other seller who is acting as a business, the consumer purchase rules also apply. If a defect manifests itself within one year of taking possession of the dog (for example, genetic disease, chronic illness, behavioural disorder caused by poor socialisation), the dog is deemed to have been defective when it was taken over, unless the nature of the animal or the specific defect precludes this. In general, a defect may be alleged if it manifests itself within two years of taking over.

In the event of a defect, the buyer has the following rights:

  • to demand remedy (e.g. reimbursement of the costs of treatment),
  • a reasonable discount on the purchase price,
  • replacement – but usually unrealistic for an animal,
  • or withdraw from the contract, i.e. return the dog and demand a refund.

There are pitfalls tomaking a claim – for example, it cannot be made because of an illness acquired after the dog was taken in (for example, a virus). In any case, the buyer should always carefully keep the veterinary reports, examination results, communication with the seller and the proof of purchase. However, in the case of consumer purchases, if the defect becomes apparent within the first year of taking possession, it is presumed to have existed at the time of taking possession, unless the seller proves otherwise or the nature of the animal or the defect precludes it.

What are the risks of buying without a contract

Particularly in so-called breeders or sales of animals through advertisements, where there is no background or health check, it is a major mistake to buy a dog without a contract. Such puppies often suffer from hidden defects, are not properly vaccinated or socialised and often have not even passed a vet check. Without a contract, it is then virtually impossible to recover compensation or refund. You have no way of proving what was actually agreed between the buyer and seller. Therefore, even if you buy a dog without papers, always ask for a contract.

Tip for article

It pays to have liability insurance for your dog too. All it takes is for a dog to run into the road unexpectedly and cause an accident, and you could be liable for the consequences and pay compensation. The insurance will save you a lot of expenses at such a time.

Breeders used to have ethical conditions in their contract

Some breeders are particular about who they sell their puppy to. They may include so-called ethical conditions in the contract to ensure that the dog gets into good hands. Sometimes these conditions are attached to a significantly lower price.

Legally, however, whoever buys the dog becomes the owner and has the right to decide its future. So enforcing, for example, a breeding ban or a ban on relocation to another household is very questionable. However, if the buyer voluntarily agrees to such conditions, and they are clearly and understandably worded, they may have some relevance in court.

Sample dog purchase agreement

If you are not sure what a dog purchase agreement should contain, or you are struggling after buying a puppy, contacting a lawyer is definitely a wise move. If you are interested, we can prepare a sample dog purchase agreement that you can easily modify as needed – whether you are the breeder or the buyer. The templates commonly available on the internet tend to be incomplete or contain inappropriate clauses. A legally checked version will give you certainty and protection. In addition to the contract, we will be happy to help you with any dispute resolution.

Dispute over a dog claim in practice

Judicial practice shows that disputes concerning the purchase of a dog are not exceptional and can relate to the health of the animal as well as the failure to respect the terms of the contract between the breeder and the buyer. One Czech court decision dealt with the claim of a puppy which, shortly after its acquisition, developed a serious genetic defect – severe hip dysplasia. The buyer demanded a refund and the return of the dog to the seller, which the breeder refused, claiming that the animal was fine at the time of sale. The court concluded that this was a latent defect existing at the time of acceptance and that the buyer was entitled to rescind the contract and recover the money.

Thus, even in the case of an ’emotional good’ such as a dog, legally binding documents play an important role and can determine the success or failure of any litigation. The sales contract is thus not just a formality but an essential instrument of legal certainty.

Don’t forget that you must register your dog with the relevant authority and start paying the local fee for it.

Summary

A dog purchase contract is not an unnecessary formality. It helps to avoid disputes about the health, origin, price and terms of delivery of the dog. Although the Civil Code expressly provides that a live animal is not a thing, the rules on things apply mutatis mutandis in the case of a purchase, unless this contradicts the nature of the animal. This is particularly important when dealing with defects, claims or withdrawal from the contract.

A good contract should accurately identify the seller, the buyer and the dog. For a dog, it is advisable to include the breed, sex, date of birth, chip number, pedigree, vaccinations, deworming, known medical conditions, and documents handed over. It should separately state the price, method of payment, date of delivery and liability for defects.

Pay particular attention to contracts that contain prohibitions against resale, spay/neuter obligations, right of redemption, or other breeding conditions. Some such clauses may be useful, but others may be difficult to enforce or unduly interfere with the new owner’s rights.

If you are buying a more expensive puppy, a dog with a pedigree certificate or are already dealing with a health problem after the purchase, it is worth consulting an attorney about the contract or claim. Early document review is often cheaper than a later dispute with the breeder.

Frequently Asked Questions

Does the dog purchase contract have to be in writing?

They don’t have to, but a written contract is essential evidence. Without it, it is difficult to prove the price, the health of the dog and what the seller promised.

Can I claim my dog as normal goods?

Yes, but with regard to the nature of the animal. The main defects that can be claimed are those that existed when the animal was taken over, such as congenital or genetic defects.

What if the disease manifests itself after I buy the dog?

It depends on whether the defect was already present at the time of acceptance or whether the disease arose later. Veterinary reports and professional assessment are important.

Can a breeder prohibit the resale of a dog?

Such a provision may be included in the contract, but its enforceability is questionable. The specific wording and circumstances must be assessed.

What should be in the contract for a dog without a pedigree?

At a minimum, an accurate description of the dog, chip number, health, price, handover date, party details and rules for any defects.

Is there a difference between buying a dog from a breeder and from a private person?

Yes. The rules of consumer purchase typically apply to a breeder-business. For a private sale, the buyer protection is weaker.

Does the dog have to be chipped when sold?

The dog has to be microchipped – compulsory chipping is also related to the validity of the rabies vaccination.
