What to do when pet care instructions change after booking
If an owner adds a visit, changes a care task or leaves instructions that differ from your agreement, clarify what has changed and check what you can cover. Confirm the revised arrangement in writing, including who will handle any task you cannot take on.
You agreed to morning and evening visits. Then a message arrives: could you come at midday too? Or the care sheet waiting at the house includes a task you never discussed.
The owner may have a new work commitment, a delayed return or updated veterinary instructions. Whatever prompted the change, both of you need to know which tasks are covered. A quick “thanks for letting me know” can leave that unresolved.
Start with what is different
Compare the new request with the visits and tasks you agreed to. Ask about the change directly: an extra visit, a longer stay, a different time, a new task or another person helping with care. Find out which dates it affects and when it needs to start.
Keep the question factual. “The sheet includes a midday visit, but our booking has morning and evening visits. Who is covering midday?” is easier to answer than “The instructions are confusing.”
If two instructions conflict, identify both. Do not quietly combine them into your own version. A message, a note on the counter and an older care sheet can all remain visible after one of them has become outdated.
Fictional example · Lucia, Oliver, Adrian and Scout
An extra visit needs an answer
Oliver and Adrian have booked Lucia for morning and evening visits with Scout. After their plans change, they ask for a midday visit as well. Lucia already has another commitment then.
She can still do the agreed visits. She cannot assume the new one will somehow fit between them. Her reply makes the gap visible:
“Thanks for the update. I have Scout’s morning and evening visits confirmed. I’m not available for the additional midday visit. Could you confirm who will cover it? Once that is arranged, let’s put all three visits and the person responsible for each on the same care sheet.”
Adrian confirms that he can return home for the midday visit. They add his visit to the plan and agree that he will tell Lucia when he has finished. Lucia’s original visits remain booked.
This is a fictional scheduling example, not a customer story. It assigns no medication, diagnosis or treatment to Scout.
Check time, skills and the booking
Before accepting an additional task, work out what it involves. Could it require another journey, more time in the home, different access or training you do not have? Be specific about what you can offer and what you cannot cover.
If the change affects the service or price, discuss that before confirming it. Check whether the service you booked through requires a booking update too. A conversation about a new task should end with a clear answer about whether it is included.
If you cannot take it on, explain the limit promptly so the owner can arrange suitable help. If the stay has already begun, identify any immediate gap and contact the owner and the agreed backup. Do not leave an essential task with everyone assuming someone else accepted it.
If the change involves medication
Ask for the current veterinary directions and point out any difference from the instructions you already have. If the medicine label and the owner's message disagree, seek clarification from the prescribing clinic with the owner involved. Do not decide that the newest message must be the correct dose.
The FDA advises reading medication labels, following directions and asking the veterinarian about amounts, timing and missed doses. Changing a visit to suit your availability does not establish that a different medication time is appropriate.
If a medication task is due while instructions remain unclear, contact the veterinarian or the agreed emergency clinic promptly for guidance. A pending clarification is not a reason to invent a dose or silently omit one.
Write the agreement everyone will use
After a call, send a short written recap and ask the owner to confirm it. Pet Sitters International recommends written follow-up for care requests discussed verbally, including repeat bookings.
Include the affected dates, the task, who has accepted it and when the update applies. Keep unresolved requests visibly separate. In Lucia’s example, the confirmation could read:
Example confirmation · visit coordination only
- Visits covered by Lucia
- Morning and evening, on the booked dates.
- Additional midday visit
- Adrian has confirmed he will cover it on the affected day.
- Between visits
- Adrian will send Lucia an update after his visit. Any further change needs a new confirmation.
Update the care sheet everyone uses and clearly mark the previous version as superseded. Keep earlier messages for context. If a second sitter or family member is involved, make sure they receive and acknowledge the part they are covering.
The agreed plan and the record of completed care have different jobs. A new plan explains what should happen next; it should not rewrite what someone previously reported doing.
Leave one clear next step
Before closing the conversation, check: is the change confirmed, still awaiting clarification, or waiting for someone to cover it? Name the person taking the next action.
For a medication handoff, use the free care sheet and daily log to organize the current instructions, contacts and reported actions. Keep the visit agreement alongside them so a new request does not disappear into a chat.
