Start With the Mother, Not the Litter
The puppies will be appealing; that is not evidence of anything. Look at their mother first. She should be on site, clearly the dog who whelped this litter, in good body condition, with a clean coat and bright eyes, and she should be reasonably comfortable with strangers near her puppies — wary is normal, frantic or aggressive is information. Her temperament is the single best preview of the adult dogs these puppies may become, and her health is half their inheritance. If the mother is "not available to see" for vague reasons, treat that as a serious problem, not a scheduling hiccup.
Read the Room the Puppies Live In
Puppies raised in the home live among household noise — kettles, doorbells, televisions, footsteps — and that early exposure shapes steadier adults. Check that their pen or room is clean and dry, with a separate toilet area the puppies can reach, fresh water, and toys or objects to investigate. A strong smell of waste, puppies kept in a distant shed or garage, or a litter that flinches from a normal speaking voice all point the wrong way. Watch the puppies themselves: healthy litters are curious, wobbly-bold, and settle to sleep after play rather than crying constantly or lying listless apart from the group. Handle a puppy or two if the breeder invites it: a healthy puppy feels solid rather than bony, has clear eyes and clean ears, breathes easily, and recovers quickly after a gentle startle. Check under tails for soreness and watch how each puppy moves — play should be clumsy, not stiff or reluctant.
Paperwork That Should Exist Without Awkwardness
Ask to see, not just hear about, the records: the mother's vaccination history, the puppies' worming dates and first vet checks, microchip paperwork where it applies, and the breed-relevant health test results for both parents — hips, eyes, or inherited conditions depending on the breed. A careful breeder produces a folder, not excuses. Also ask what food the puppies are weaned onto, what socialisation they have had with children, other dogs, car journeys, and being handled, and what happens if you cannot keep the dog later in life; good breeders want their puppies back rather than passed on.
Notice How the Breeder Handles You
Expect to be interviewed. A responsible breeder asks about your home, work hours, experience, and plans for training, and may refuse a sale that does not fit the breed. Be wary of the opposite: multiple litters of different breeds available at once, pressure to decide on the spot, a puppy offered much younger than eight weeks, or willingness to hand a puppy over without any questions at all. Those are sales patterns, not breeding patterns.
Leaving With a Puppy Means Leaving With His Story
When you do choose, the folder matters as much as the puppy: his vet checks, worming, food, and his parents' test results are the foundation of every future vet visit. Keeping that bundle together in KinsLe's Pet Passport means the health story your breeder started travels with your puppy to his first check-up and every one after.
