Selling a pet online in Ireland comes with real responsibilities. Whether you’re rehoming a beloved family dog, selling a litter of puppies, or finding a new home for small pets, Irish law has very clear rules designed to protect animals and ensure buyers know exactly what they’re getting. At PetsIreland, we support ethical, responsible pet ownership — and that starts with helping every seller understand their legal obligations before listing a pet.
If you’re thinking of advertising a dog, cat, rabbit, bird or any other companion animal online, this guide covers everything you need to know to stay compliant, protect your pets, and maintain trust with Irish buyers.
Minimum Legal Requirements When Selling Pets Online in Ireland
Ireland has some of the strongest pet welfare regulations in Europe, and they apply whether the sale happens in person, through social media, or via an online marketplace like PetsIreland. These rules exist to prevent puppy farming, protect animal welfare, and safeguard buyers from illegal or unethical sellers.
Below are the core legal requirements every online seller must follow:
Minimum Age Requirements
Pets — especially puppies and kittens — must be old enough to be safely separated from their mothers.
- Puppies may not be sold or supplied under 8 weeks of age.
- Similar minimum ages apply to kittens, rabbits and other small mammals, though sellers should always follow best-practice welfare guidelines even where law is less specific.
Young animals being sold too soon can face social, developmental, and health issues. For that reason, any PetsIreland listing showing very young animals will be flagged and removed.
Mandatory Microchipping for Dogs
All dogs in Ireland must be:
- Microchipped before sale,
- Registered on an approved Irish microchip database, and
- Advertised with their microchip number visible in the listing.
This ensures traceability and prevents illegal breeding or smuggling. If a seller cannot provide a valid microchip number, the dog cannot be legally sold.
Seller Registration Rules (The 6-Pet Rule)
If you sell or supply six or more pets in a single year, you MUST:
- Register with the Department of Agriculture, Food & the Marine (DAFM) as a Seller/Supplier of Pet Animals, and
- Register the premises from which the animals are sold.
This rule applies whether you are a breeder, hobby seller, or simply have multiple litters in one household. Failure to register is an offence.
PetsIreland strongly encourages transparency — and registered sellers can include their DAFM number on their listings to build trust with buyers.
What Information You Must Include in an Online Advertisement
Irish law requires specific information to be shown in any online pet advert. These details help buyers make informed, safe decisions and protect animals from being traded in poor conditions.
Every online listing must include:
- Accurate Description of the Animal
This includes:
- Breed (or “Mixed Breed” if unknown),
- Age,
- Gender,
- Colour/markings,
- Any relevant medical or behavioural notes.
Honesty is essential — misleading a buyer can result in legal consequences and permanently damage trust.
- Country of Origin
If the pet was bred outside Ireland, this must be stated clearly. Buyers have a right to know if the animal has been imported.
- Microchip Number (Dogs Only)
As required by law, this must appear publicly in the advert. Listings missing a microchip number will be rejected on PetsIreland.
- Seller Registration Number (If Applicable)
If the seller meets the 6-pet rule, their DAFM registration number must be included.
Record-Keeping Obligations for Frequent Sellers in Ireland
If you sell or supply six or more pets per year, you are legally required to keep detailed records for at least three years. These records must include:
- Description of each animal (breed, markings, sex, age)
- Microchip number if applicable
- Where the animal came from
- Who it was sold or supplied to
- Any veterinary treatments provided
- Date of sale/supply
These records must be available for inspection by authorised officers.
Even if you only sell an occasional pet, keeping basic records is still good practice — it helps protect both you and the buyer.
Ensuring Pets Are Sold Ethically and Safely Online
Legal obligations aside, ethical responsibility is just as important. At PetsIreland, we strongly encourage every seller to:
Provide a Safe Environment for Viewings
Buyers should meet the pet in a clean, safe, and comfortable setting. Avoid roadside handovers or rushed exchanges. Ethical transactions build trust and ensure pets go to suitable homes.
Be Transparent About Behaviour and Health
If a pet has anxiety, special dietary needs, or recent vet treatments, tell buyers upfront. Transparency protects both parties and ensures pets are matched to homes that can meet their needs.
Avoid Overbreeding
Responsible breeders focus on welfare — not volume. If you list multiple litters per year, ensure you meet registration and record-keeping rules and follow best-practice breeding standards.
Confirm Buyers Understand Their Responsibilities
Every dog owner in Ireland must have:
- A valid dog licence
- A microchipped dog
- A safe living environment
- Control over restricted breeds where applicable
Good sellers help buyers prepare for these responsibilities, reducing the chance of pets becoming unwanted later.
