What a trial night is meant to test
A trial boarding night is a rehearsal, not just a sleepover. It tests whether your dog can eat away from home, rest in an unfamiliar run or room, accept handling from people he has only just met, and cope with the sounds and smells of other dogs nearby. One calm night does not guarantee a longer stay will go smoothly, but a difficult night tells you exactly what to work on before you book real travel. That is why the record matters as much as the night itself: without written feedback, all you keep is a vague impression from a busy pickup desk.
The feedback to request before pickup
Ask for specifics while the stay is still fresh for the staff who were actually there. Useful notes cover how much of each meal he ate and whether he drank normally, whether he toileted on the schedule you described, how he settled at lights-out, and whether there was barking, pacing, drooling, or attempts to guard his space. Ask who fed and walked him, because a dog who accepts one handler and avoids another is telling you something different from a dog who was unsettled with everyone. If anything was refused, vomited, or left untouched, ask for the time it happened rather than a general summary.
Also ask about the parts of the night you cannot see from the lobby: how he reacted when neighboring dogs were let out, whether he joined group play or watched from the fence, and how he behaved on the lead moving between areas. These details decide practical questions for the real stay, such as whether he boards better in a quieter wing, needs his own blanket from home, or should arrive earlier in the day so he settles before the evening routine.
How to file the kennel's notes
File the feedback the same day, while you can still fill gaps from memory. Keep the kennel's written notes together with the booking confirmation, the vaccine records you submitted, the food and feeding amounts you sent, and the emergency contact the kennel held. Add one short paragraph of your own covering how your dog seemed in the first hours back home: appetite, thirst, sleepiness, clinginess, or loose stool after the stay can all be part of the picture, and none of it will be in the kennel's version.
Write plainly and date everything. "Ate half of evening meal, drank well, barked at kennel door for the first hour, slept after midnight" is far more useful in six months than "seemed a bit stressed." If the kennel gave verbal feedback only, transcribe it at the desk or in the car and note the name of the person who gave it, so a future stay can be discussed with the same detail.
What the notes should change next time
Read the filed notes as instructions for the next booking. A dog who skipped meals may need his own food pre-portioned and a quieter feeding spot agreed in advance. A dog who paced at night may settle better with an earlier drop-off, a longer walk before arrival, or a familiar-smelling item in his bedding. A dog who thrived needs that recorded too, including which staff and routines suited him, so you can ask for the same setup again.
Keeping the trial-night record, the vaccine papers, and the feeding notes together in your KinsLe Pet Passport turns one test night into a boarding file any future kennel, sitter, or vet can read in minutes.
