Why the breeder matters

A responsible breeder plans litters for health and temperament, raises them in a home environment and cares where every puppy or kitten goes. A puppy farmer or casual back-street breeder cares about the sale. The difference shows in everything they do — if you know what to look for.

What a good breeder looks like

Expect all of these, not just some.

  • You see the litter with their mother, in the home where they were raised
  • The breeder asks you as many questions as you ask them
  • Health tests relevant to the breed are done on the parents, with certificates you can verify
  • Puppies or kittens stay with the mother until at least eight weeks
  • The breeder provides a contract, vaccination and microchip records, and takes the animal back at any point in its life if things go wrong
  • They breed one or two breeds, occasionally — not many breeds, constantly

Red flags

Any one of these is reason to walk away.

  • Offers to meet in a car park or deliver the animal to you
  • The mother is 'out' or 'at the vet'
  • Multiple litters or breeds available at once
  • No health testing, or excuses about paperwork
  • Pressure to pay a deposit immediately or take the animal today
  • Very cheap prices for fashionable breeds, or 'rare' colours sold at a premium

Online adverts are the front line of puppy farming

Criminals rent homes to stage litters and use fake photos and stories. If anything feels rushed, secretive or too easy, walk away — there will always be another litter.

Useful schemes

In the UK, the Kennel Club Assured Breeders scheme and breed club health schemes are useful starting points, though membership alone is not a guarantee. For cats, the GCCF and breed clubs list breeders who health-test. Wherever you buy, your own eyes and questions are the real safeguard.

Frequently asked questions

Should I consider a rescue instead?
Absolutely — rescues have puppies, kittens and purebreds as well as adults, and staff know their animals' temperaments. A reputable rescue matches you to an animal rather than selling you one.
Is it safe to buy a puppy online?
Online is where most problem breeders advertise, but it is also where good breeders list. The rules are the same: see the litter with the mother in the home, verify health tests, and never pay before visiting.
