Build up in puppy-sized steps
An adult dog with boarding experience walks into a kennel with a history of good stays behind him. A puppy has none of that, so the preparation does the work instead. Start with a visit where she simply sniffs the place, meets the staff and comes home again, then a short daytime stay, then a single night if your trip allows that runway. Keep each step cheerful and brief enough to end well. At home, practise the separations boarding involves: sleeping in her own bed or crate rather than on yours if that is the kennel arrangement, settling while you are in another room, and being handled gently by people she does not know well. A puppy who has already learned that being apart from you is survivable will read the kennel as another version of a familiar thing, not a shock.
Pack comfort and keep food and rhythm identical
Send the bedding she actually sleeps on, unwashed enough to carry home's smell, plus one worn item of your clothing if the kennel allows it. Pack her exact usual food, measured out where that helps, with her feeding times written down; young puppies typically eat more frequent, smaller meals than adults, and a sudden food change on top of a new environment is a reliable recipe for an upset stomach. Note her toilet rhythm honestly — how often she needs to go out, including overnight — and her current stage with housetraining, so staff can match breaks to her bladder rather than to the adult dogs' schedule. Add the safe chews she is allowed, because a teething puppy in a new place will chew something, and it may as well be the thing you chose.
Ask the kennel puppy-specific questions
Before booking, confirm what proof of vaccination the kennel asks for in a puppy whose course may be recent, and how they time stays around it. Ask where puppies sleep and rest — young dogs need far more sleep than adults and should have quiet space away from the main adult runs — and how play is handled, because a small puppy bowled over repeatedly by big adolescents can come home frightened of other dogs. Ask about overnight checks, since a puppy may need a toilet break when adult dogs sleep through, and about exercise limits: growing joints are not built for marathon play sessions, however enthusiastically the puppy volunteers. A kennel that answers these questions specifically, rather than waving them away, is telling you it genuinely runs a different routine for the young ones.
Write the puppy notes like a diary of her day
Your handover notes should read as her day in order: wake, toilet, meal, play, nap, with her real times filled in. Include the words and cues she knows, how you settle her when she is overtired and bitey, what her stress signals look like — lip-licking, hiding, frantic zooming — and what helps: a chew, a cuddle, or simply being left to sleep. Note anything she is frightened of, from vacuum cleaners to men in hats, so staff are not blindsided. When you collect her, expect a tired puppy and a day or two of clinginess or broken housetraining at home; that is normal settling, not a verdict on the kennel. KinsLe Care Pass pulls her feeding times, toilet rhythm, cues and comfort details into one temporary handover the kennel can follow exactly, so the routine she knows at home is the routine she gets while she is away.
