Boarding asks an elderly dog to relearn a building, a sleeping place and a set of strangers all at once. A sitter at home asks only one new thing of her: a different person performing a familiar day in familiar rooms. Your work is making sure that person can perform it faithfully.
Build the Brief Around Her Exact Day
Write her day as a timed sequence, in the order she lives it. Start with her morning toilet trip, where she goes, how long she takes and what helps her start the day; then breakfast, her medication routine exactly as her vet has directed, her rest pattern and the length and route of a good walk for her. Include how she asks to go out, how often she usually toilets, what her normal appetite looks like and the small comfort cues that tell a sitter she wants company, a blanket adjusted, a door opened or to be left undisturbed.
Cover mobility in the concrete terms of your house. Say which routes she manages well, where any ramp sits, which floors she finds slippery, which steps she no longer attempts and where she sleeps so she can reach her toilet route without a difficult journey in the night. Describe honestly what a poor day looks like for her: slower rising, a skipped meal, restlessness, seeking a corner, or needing the garden more often, and what you usually do in response. The sitter should never roll or turn her to reposition her; she rises and resettles herself in her own time, and the sitter's role is to wait, keep the path clear and offer only the support she normally accepts.
Leave prescribed items labelled and cleaning supplies within easy reach.
Adapt the Sitter's Habits, Not Hers
Introduce the sitter over several visits before any overnight booking. Let the sitter watch an evening routine first, then run that routine while you are present, feeding her, following her toilet pattern and settling her where she sleeps. Those visits teach the details a brief cannot carry: her pace on the lead, the pauses she takes, the order in which she likes things done and how she signals that she has finished outside.
Make the direction of travel explicit in your instructions: the sitter adapts to her routine, not the reverse. Meal times do not drift to suit the sitter's plans, walks do not move to hotter or busier hours, furniture and beds do not get rearranged for tidiness, and visitors do not arrive to meet her. If she needs the garden in the night, the sitter sleeps where that can be heard and answered, as part of the overnight arrangement agreed in advance.
Because the sitter is paid, get the provider's agreed terms confirmed in writing before the booking is firm: the trial terms, the overnight arrangements and the rates, plus how vet travel or extra nights would be handled if your return is delayed.
Set Vet, Backup and Daily Reporting in Advance
Tell her usual practice that she will be in a sitter's care at home, leave signed authorisation for emergency care and a payment arrangement the practice has agreed, and name a local backup person who knows her and can step in if the sitter is taken ill. Agree what should trigger a call to the vet, what should trigger a call to you, and in what order, so a worried sitter at midnight is following a plan rather than improvising one.
Ask for a daily report with real content: meals eaten, medication routine completed, toileting, walks managed, sleep and mobility, written in plain words while the day is fresh. On your return, read those reports with the sitter if you can, note anything that differed from her normal pattern, and update the brief while the experience is recent, so the next booking starts from what you learned rather than from the old version. The sitter works from Care Pass through KinsLe during the booked days alone, opening her exact routine rather than a general summary of elderly care.
