A walker can see that your dog is friendly and loves the park. What she cannot see is the health picture underneath, and midday is when it matters: the hottest part of the day, a dose that may fall due, and an owner at work rather than in the next room. Brief for the invisible before the first walk, not after the first scare.
Allergies and conditions she cannot guess
Start with allergies, and describe what they actually look like in your dog rather than naming the trigger alone. A walker told only that chicken disagrees with her learns little; a walker told that within an hour of the wrong treat she scratches her ears raw, shakes her head and may be sick knows what to watch for and why nobody on the walk should hand her scraps, however kindly meant. Name the safe treats she may have, if any, and where they are kept.
Then cover ongoing conditions in working terms: what each means for an ordinary walk, not its medical history. A heart condition may mean steady pace, no steep climbs and rest whenever she asks for it. Sore joints may mean grass over tarmac and a shorter route on cold days. Any condition that can change her state quickly needs its early signs spelled out, because the walker is the only person positioned to notice them.
Medication timing, heat and exercise limits
If a dose falls due while she is out, the instruction is fixed and not hers to interpret: the medicine, the dose and the time exactly as prescribed, written down, with what to do if she spits it out or refuses it — which is to record that and tell you, never to improvise, double up or quietly skip it. If no dose falls due, say so explicitly, so the walker is not left wondering whether she has missed a task.
Heat limits deserve their own line in summer. State her ceiling plainly: the route length she handles comfortably, the point at which the walk shortens to a shaded toilet break, and the signs that mean stop in shade and offer water. Exercise limits belong beside heat, because the two combine: a dog allowed ten minutes of ball play in winter may be allowed none at midday in July, and the walker should not have to derive that from enthusiasm — hers or the dog's.
The handover note she carries
Gather it into one note, paper in the treat pouch or a phone copy, with these fields and no others: who to call and what to do if she seems unwell; the warning signs for ending the walk early; her limits for exercise and heat; any dose due during the walk, with its timing exactly as prescribed; any ongoing conditions; and her allergies, described by how a reaction shows in her. Six fields, readable in under a minute, identical every time so a regular walker notices instantly when something in it changes. Update it the day a prescription, limit or reaction pattern changes, not at some tidier later date.
If she seems unwell on the walk
Give the sequence in advance: stop, move her into shade or shelter, offer water without forcing it, and call you; if you cannot be reached, call the second contact, and for collapse, laboured breathing, repeated vomiting, a suspected allergic reaction or anything that frightens the walker, the instruction is the veterinary practice number on the note and transport there, not a wait-and-see walk home. Ask for a message after every walk covering how far she went, whether the dose was taken if one was due, and anything noticed — appetite for the walk itself, stiffness, scratching, a loose stool. That short report is how patterns surface while they are still small.
Health notes should travel with the task, not sit in a folder at home the walker cannot open. KinsLe handles that through Care Pass sharing: you grant the walker temporary, scoped access to the health brief for her walks, and that access ends when the arrangement does.
