A sitter can be devoted and still give a medicine wrongly if the instructions leave any step open to interpretation. Guess-proof writing means the sheet answers every question at the moment it arises, in the order it arises, without the sitter needing to interpret handwriting, remember a conversation, or decide anything that belongs to you or your vet.
What the Sheet Must State
Open with the medicine's label name, copied word for word from the bottle, because a sitter searching a cupboard for a description like the small white tablet may find two similar bottles and choose wrongly. State where the medicine is kept in exact household terms, such as the top drawer beside the kettle, and keep the sheet itself in that same place. Give the serving times as clock times tied to the day's anchors, for example with breakfast and with the evening meal, exactly as prescribed. Then describe how the serving is given, as prescribed and as your dog actually accepts it: hidden in a named food, placed at the back of the tongue if that is the agreed method, or given another way your vet has approved. Add the vet's number in large print, your own number, and the order to use them in. Close the sheet with an initialled chart, one row per serving, so the sitter signs each serving as it happens and you can see the completed record when you return.
The Refusal Plan, Written Before It Is Needed
Dogs refuse medicines for sitters far more readily than for owners, because the routine, the hands, and the confidence all feel different. Decide the plan now, while nobody is flustered. If your dog will not take a serving, the sitter should note the time and what happened on the chart, try once more a short while later only if your written plan allows that, and then phone you or the vet for direction. Two rules belong on the sheet in unmistakable words: never force a serving into a dog who is backing away, snapping, or distressed, and never give a second serving to compensate for one that was refused, spat out, or only partly swallowed. A missed serving reported honestly is a manageable problem. A doubled serving given out of worry is a veterinary problem, and a forced serving can cost the sitter a bite and the dog its trust in the routine.
Rehearse It Once, in Person
Paper alone leaves gaps that only appear in practice: where your dog stands for the routine, how the bottle opens, which treat actually hides a tablet from this particular nose. Run the serving once with the sitter present before you travel, talking through each line of the sheet as you do it, then watch them do the next serving while you correct anything gently. That single rehearsal converts your written method into their muscle memory, and it surfaces questions while you are standing there to answer them. Leave the medicines, the sheet, and the chart together, and ask for a photo of the completed chart each evening if you want quiet reassurance without nightly phone calls.
What Never Belongs on the Sheet
Leave out any instruction that asks the sitter to judge a dose, change a time because the dog seems better or worse, substitute a different medicine, or stop a course early. Those decisions sit with you and your vet, and a guess-proof sheet protects the sitter by saying so plainly and giving them your number instead. KinsLe supports that clarity through the Pet Passport, which travels with your dog as a single records packet, letting any covering helper read the identical instructions rather than a hurried copy.
