How to choose a dog that fits your life
The best dog fits your home, time and budget. Before you look at adverts, decide on size, energy, grooming, how long the dog will be alone, who lives with it, and whether you want a puppy or an adult. If you rent, check your tenancy. Our best family dogs guide goes through this.
Lucy’s Law: the rule every UK buyer should know
In England, Lucy’s Law (in force since April 2020) means anyone buying a puppy or kitten under six months must deal directly with the breeder or a rescue centre, not with a third-party dealer. Similar protections exist in the other UK nations. If a seller says they are selling on someone else’s behalf, walk away.
Your main options
| Source | Good for | Watch for |
|---|---|---|
| Responsible breeder | Predictable breed, health-tested parents, breeder support | Waiting lists, cost, and breeders who skip tests |
| Rescue or rehoming centre | Adult dogs, lower fees, saving a life | Unknown history; patience needed |
| Online adverts | Convenience | Puppy farms and scams |
See breeder or rescue.
What a responsible breeder looks like
- You meet the puppy with its mother, at the place it was born and raised.
- Both parents have the health tests that suit the breed, with results you can see (for example BVA/Kennel Club hip and elbow scores).
- There is a written contract and the breeder takes the dog back at any age.
- The breeder asks you questions and does not rush you.
- The puppy is at least eight weeks old, microchipped, and has had age-appropriate vet care.
The Kennel Club’s Assured Breeder Scheme is one sign of effort, but not a guarantee, so still check everything yourself.
What it costs
PDSA estimates the basic minimum cost of owning a dog at £69 a month for a small dog, £83 for a medium dog and £116 for a large dog (2024), which is a lifetime minimum of about £6,200 to £18,800 depending on size and breed. That excludes the purchase price and vet fees for illness or injury. See what a dog really costs.
Avoiding scams
Pet fraud is common, and Action Fraud warns buyers to be careful. Red flags include a very low price, a seller who will not let you see the puppy with its mother, and pressure to pay a deposit quickly. See puppy scams.
How K9PN matches you with a professional
K9PN is not a marketplace and we do not sell dogs. We refer people to experienced, independent professionals, and we look at openness about the dogs and their parents, health testing, written contracts, and honest aftercare. We are still building our UK network, so put your full postcode in the form and we will tell you if we can match you.

Common questions
Where is the safest place to buy a puppy in the UK?
From a responsible breeder who lets you meet the puppy with its mother, shows health tests and gives you a written contract, or from a rescue. Lucy’s Law bans third-party sales of puppies under six months in England.
What is Lucy’s Law?
In England, it requires anyone buying a puppy or kitten under six months to deal directly with the breeder or a rescue centre, not a third-party dealer.
How much does a dog cost in the UK?
PDSA estimates the basic minimum cost at about £69 to £116 a month depending on size, before the purchase price and vet bills. See our cost guide.
How can I tell if a puppy advert is a scam?
Warning signs include a low price for a popular breed, refusing to let you see the puppy with its mother, and pressure to pay a deposit. Never pay for a puppy you have not seen.
Should I buy or adopt?
Neither is always better. Adoption can save a life and costs less. A good breeder gives predictability and health-tested parents. See breeder or rescue.

No. K9PN is a referral service and does not breed, sell or train dogs. We pass your request to a professional who covers your area, if we can match you. It costs nothing to send a request. We are still building our UK network.
