Straight-talking guide to UK puppy selling laws, licensing rules and responsible advertising so you can place your litter safely and legally.
Selling Puppies in the UK: Laws, Licensing & Responsible Advertising
If you are breeding and selling puppies in the UK, you are carrying out a regulated activity – even if you only plan one litter. This guide sets out, in clear terms, what the law expects from you, how licensing works across each UK nation, and how to advertise your litter responsibly on MyPetConnect.
Important: This guide is for general information only. Always confirm details with your local council before you breed or advertise.
1. Do You Need a Breeding Licence?
The rules vary depending on where you live and whether you are considered to be “in the business” of breeding dogs for sale.
1.1 England – Animal Welfare (Licensing of Activities Involving Animals) Regulations 2018
You will usually need a breeding licence in England if you:
- Breed 3 or more litters of puppies in any 12-month period and sell any of the puppies, unless you can prove that none of the puppies were sold as puppies or adults.
- Breed dogs and advertise a business of selling dogs, even if you produce fewer than 3 litters a year.
Councils also use a “business test” to assess whether your activity is commercial (e.g., repeated adverts, profit, organised sales).
Licensed breeders receive a 1–5 star rating. Your licence number and issuing council must be displayed in every advert.
1.2 Wales – Animal Welfare (Breeding of Dogs) (Wales) Regulations 2014
You must be licensed in Wales if you:
- Breed 3 or more litters in any 12-month period, or
- Run a business that breeds and sells dogs.
Local authorities may also treat advertising or supplying 3 or more litters as a trigger for licensing. Always check with your council.
1.3 Scotland – Breeding of Dogs Act 1973 & Breeding and Sale of Dogs (Welfare) Act 1999
In Scotland, licensing depends on whether you are operating a breeding establishment. This means any premises where the business of breeding dogs for sale is carried out.
While many councils use “3 or more litters” as a practical indicator, the legal test focuses on whether it is a commercial activity.
1.4 Northern Ireland – Welfare of Animals (Dog Breeding Establishments) Regulations 2013
You need a licence if you meet any of the following:
- Own 3 or more breeding bitches, and/or
- Breed or sell more than 3 litters a year, and/or
- Advertise or operate as a business breeding or selling puppies.
1.5 The Safe Rule
If you are anywhere near the 3-litter threshold, or you are clearly trading for profit, speak to your local council before breeding again.
2. Lucy’s Law & the Ban on Third-Party Sales
Lucy’s Law was introduced to stop puppy farming and low-welfare dealers.
- Since 6 April 2020 in England, commercial third-party sales of puppies and kittens under 6 months old are banned.
- You can only buy from the breeder who bred the litter, or from a genuine rescue.
Scotland and Wales have now implemented similar bans. The direction is clear: no dealers and no middlemen.
3. The 8-Week Rule & Keeping Puppies With Their Mother
Modern welfare regulations state that:
- Puppies must not be sold under 8 weeks old.
- Puppies under 8 weeks must not be separated from their mother unless a vet confirms a welfare reason.
- Licensed breeders must show puppies with their mother in the place they were bred.
Responsible breeders treat 8 weeks as a minimum, not a target.
4. Microchipping Requirements
The UK requires all dogs to be microchipped and registered:
- All puppies must be microchipped by 8 weeks of age.
- The breeder must microchip and register puppies before sale.
- The buyer must update the registration once they take ownership.
A puppy must not be sold unchipped unless a vet has issued a written exemption.
5. Hobby Breeders & “One-Off Litters”
Your responsibilities are the same whether you breed one litter or ten. You must:
- Use healthy, suitable parents.
- Follow a proper worming schedule (typically every 2 weeks until 12 weeks, then every 3 months).
- Keep accurate health records.
- Provide truthful information about vaccinations, microchipping and health tests.
- Socialise puppies gradually and safely.
6. Advertising Puppies Responsibly on MyPetConnect
MyPetConnect aims to meet the PAAG (Pet Advertising Advisory Group) standards to ensure safe, lawful adverts.
6.1 Your Advert Should Include:
- Licence number and issuing council (if licensed).
- Accurate ages of all puppies.
- Real photos of the puppies and mother.
- Clear information on microchipping, worming, vaccinations and health tests.
- Honest breed information.
- Your location (town/city and county).
6.2 MyPetConnect Will Not Allow:

7. Vetting Puppy Buyers Properly
Finding a buyer is easy. Finding the right buyer takes effort.
7.1 Questions to Ask Buyers
- Have you owned dogs before?
- How long will the puppy be left alone daily?
- Who lives in the home?
- Have you researched this breed’s needs?
- Are you prepared for insurance and routine vet care?
7.2 Meeting in Person
- Always meet face-to-face.
- Show puppies with their mother.
- Never arrange handovers in car parks or neutral locations.
8. Puppy Pack Essentials
Before puppies leave, you should provide:
- Contract of sale.
- Microchip paperwork.
- Vaccination card.
- Worming and flea treatment history.
- Health test certificates (if applicable).
- KC documentation (if registered).
- Insurance cover note (optional).
- Breed information sheet.
- A comfort item that smells of the mother.
- 4–5 days’ worth of current food.
9. Socialisation & Early Training
Proper early experiences make a huge difference to a puppy’s confidence. Introduce:
- Normal household noises.
- Gentle handling by trusted adults.
- Age-appropriate toys and surfaces.
- Short, calm car journeys.
10. Checklist: Selling a Litter Properly
- Confirm whether you need a licence.
- Health-test parents and plan responsibly.
- Worm, monitor and socialise pups correctly.
- Microchip before sale.
- Advertise honestly and legally.
- Vet your buyers.
- Never sell under 8 weeks.

11. Final Word
Breeding carries serious responsibility. If you keep your numbers sensible, follow the welfare rules and advertise honestly, you will protect your puppies, yourself and the reputation of responsible UK breeders.
If in doubt, speak to your council’s licensing team or your vet before breeding or advertising.
