Picture a pet sitter arriving at your home on the first morning you are away. They find the dog's food in the pantry but are not sure how much to give. The prescription medication is in a cabinet but there is no label visible from where they are looking. The vet's number is not written down anywhere. They text you but your phone is in airplane mode. They do their best, which is all anyone can do in that situation, and you come home hoping everything went fine.
This scenario is completely preventable. It does not require an elaborate system or extensive preparation. It requires about 30 minutes of focused work before you leave, organized around one principle: a sitter should be able to handle everything correctly without needing to reach you.

What Sitters Actually Need to Know
The instinct is to give a sitter the most critical things and fill in the rest over text if needed. This works fine when you are reachable. It breaks down completely when you are on a long flight, in a remote area, in a meeting where you cannot check your phone, or simply unavailable at the moment something comes up.
The better approach is to write down everything a sitter needs, in enough detail that they could handle care correctly with no contact from you at all. Not because you expect to be unreachable, but because preparing for that scenario covers every lesser one too.
The Pet Sitter Info Sheet template covers this on a single page. It is designed to be filled out once, updated when things change, and handed to any sitter, dog walker, or family member helping with care. The categories below map to what belongs in that document.
Feeding Instructions
"Feed him twice a day" is the beginning of an instruction, not the whole one. A complete feeding note covers:
Amount and timing. How much food, in a unit that does not require interpretation (cups, grams, pouches, not "a normal amount" or "a small bowl"). What time. Whether timing matters strictly (some dogs need to eat before a walk; others need a gap before activity to reduce bloat risk).
The food itself. Brand, variety, and where it is stored. If there are multiple foods in the house (a prescription food and regular treats, different food for different pets), be specific about which is which and what goes to which animal.
Food rules. No table scraps, or specific ones that are okay. Foods the pet cannot have for medical reasons. Whether the pet gets a dental chew after meals and where those are. Whether medication is hidden in food (and what you use to hide it effectively).
What normal eating looks like. If your dog normally finishes their bowl in under two minutes, a sitter who sees them picking at it slowly on day two knows something may be off. If your cat sometimes skips the morning bowl but always eats the evening one, that context prevents unnecessary panic.
Medications
This is the one category where "we will figure it out" is not an acceptable plan. A pet on insulin, anti-seizure medication, or a twice-daily prescription needs their doses given at the right time, in the right amount, and in the right way. A sitter who is uncertain whether a dose was already given, or whether the pink tablet goes in food or directly, or what to do if the pet vomits shortly after administration, needs answers before the situation arises.
Write out each medication with:
- The name (as it appears on the label)
- The dose (exact amount, not "one pill" if the pill is being split)
- When it is given (time of day, whether with food or without)
- How to administer it (hidden in food with cream cheese, given directly with a pill gun, liquid via syringe)
- What to do if the pet refuses or vomits the dose
- What to do if a dose is missed
If your pet takes multiple medications, leave the Medication Log template with the sitter and show them how to mark each dose when it is given. The point is not bureaucracy. The point is that nobody, including your sitter, should have to rely on memory across multiple days of care to know whether a medication was given.
Put the medications somewhere visible and clearly labeled. A bag or box with the pet's name and "medications" written on it, placed on the counter near where they get fed, removes the searching step entirely.
Emergency Contacts and the Emergency Decision
Leave three numbers in writing: your regular vet (with hours), your nearest 24-hour emergency veterinary clinic (address too, not just a phone number), and the ASPCA Animal Poison Control line, (888) 426-4435, for any suspected toxic ingestion.
Then write down your own contact number and one backup contact who can make decisions if you cannot be reached.
The most important thing you can add to this section is a simple decision-making rule. Something like: "If anything feels wrong and you cannot reach me, call the vet first. You have my full permission to take him in and authorize care. I will sort out the cost when I am back." This statement removes the hesitation that sometimes delays care when owners are unreachable.
Sitters are often uncertain whether to call the vet because they do not want to overreact, spend your money without permission, or disturb you unnecessarily. An explicit note that gives them permission and a clear action path resolves that hesitation entirely.
The Pet Emergency Info Sheet template is specifically designed for this purpose. It puts medical history, current medications, vet contacts, emergency clinic location, and care authorization on a single page. Emergency clinics see this format regularly. Handing it over when you arrive tells them what they need to know without requiring the owner to be on the phone.
Behavioral Notes That Actually Help
The most useful behavioral notes are specific warnings and specific reassurances. General descriptions of your pet's personality, while nice, do not help a sitter make real-time decisions.
Useful notes look like this:
"She will try to bolt out the front door if it opens more than six inches. Always check that she is in a back room before opening the front door."
"He growls when anyone touches his food bowl while he is eating. Do not try to take the bowl or correct this. Just let him eat and approach him after."
"She is friendly with most dogs but does not do well with large intact males. Keep her on leash and walk away from any approaching off-leash dogs."
"He hides under the bed the first night with new people, then comes out by morning. Do not worry if you do not see him for the first 12 hours."
Notes like these tell a sitter what to expect and how to handle it. They also prevent the sitter from interpreting normal behavior as a problem, or from inadvertently creating one by not knowing about a trigger.
The Pre-Trip Trial Run
For a sitter who has not cared for your pet before, a trial run before your actual trip is the single most valuable thing you can do. A two to four hour visit, while you are still home or at least reachable nearby, lets both the sitter and the pet get familiar with each other under low-pressure circumstances.
During the trial, walk through the full routine: feeding, medication administration (practice it even if you are there to supervise), where supplies are stored, how the leash attaches, whether the pet goes in and out through the yard or needs to be walked to the street. Any questions the sitter has come up during the trial rather than at 7am on day one of your trip when you are not available.
The other benefit is behavioral. Most pets adjust more easily to a new caregiver if they have met that person in a relaxed context with their owner present. The sitter has a scent, a voice, and an established baseline of being safe before they are the only person in the house.
The Handover Conversation
Beyond the written materials, a brief in-person conversation before you leave is worth having. Keep it practical, not exhaustive. Cover three things.
First: where everything is. Walk through the house and show the location of food, medication, leash, waste bags, emergency documents, and the vet's number. Do not just describe it. Show it.
Second: anything unusual happening right now. A recent vet visit, a health issue you are monitoring, a change in appetite over the past few days, a new fear or sensitivity that developed recently. Sitters cannot address what they do not know about.
Third: the emergency decision. State explicitly that you want them to contact the vet if anything seems wrong, and that they should not wait to reach you before making that call if the situation seems urgent.
Common Mistakes Worth Avoiding
Leaving instructions in your head. The most prepared pet owners still sometimes assume that a "quick briefing" is sufficient because they covered the highlights. It is not, especially for any medications, and especially if the sitter is new. Written instructions exist for 7am on day three when the sitter cannot remember whether the pill goes before or after breakfast.
Vague emergency guidance. "Call me if anything happens" is not a plan. A sitter needs to know when to call you, when to call the vet directly, and what to do if they cannot reach either. Write it down.
Leaving no backup contact. You will sometimes be unavailable. Leave one name and number for a person who knows the pet, can make care decisions, and can be reached when you cannot.
Forgetting behavioral context. A dog that barks continuously when left alone may have separation anxiety that a new sitter does not recognize as unusual. A cat that hides for the first 24 hours may seem ill to someone who has not been told this is normal. Behavioral notes prevent misinterpretation of normal behavior as an emergency.
Skipping the medication walkthrough. Reading about how to give medication and actually doing it with supervision are different experiences. If your sitter has never pilled a dog or given a liquid medication by syringe, walk through it with them before you leave. Once, with you watching, is enough to build confidence for the days that follow.
Frequently Asked Questions
How far in advance should I find a pet sitter before a trip?
For overnight or multi-day care, aim for at least two to three weeks before your departure date. This gives time for a meet-and-greet visit, a trial run, and any adjustments before you leave. Booking the same week you travel leaves almost no buffer for situations where the sitter does not click with your pet or something unexpected comes up.
Should I tell my sitter about my pet's health conditions even if they seem stable?
Yes, always. A stable condition can become unstable. A sitter who knows your dog has early kidney disease will notice changes in water consumption and bathroom habits that a sitter without that context would dismiss. A sitter who knows your cat had a urinary blockage last year will recognize straining in the litter box as urgent rather than normal. Context turns a sitter into a more capable caregiver.
My dog is reactive on leash. Should I still hire a regular dog walker?
Yes, but brief them thoroughly before their first walk. Describe exactly what triggers the reactivity, what the dog's behavior looks like when they are approaching threshold, and what the walker should do (turn around, increase distance, redirect attention). A good dog walker will appreciate the specifics. If they seem dismissive of the information or suggest they can "handle it," that is worth noting. Leash reactivity that is not managed consistently gets worse.
What should I do if my pet sitter has to leave unexpectedly mid-trip?
Have a backup contact identified before you leave. This could be a neighbor, a trusted friend, a dog boarding facility that has your pet's information on file. Leave the backup person aware that they may be called on, and make sure they have a copy of the same written instructions. A sitter emergency is rare but not unheard of, and having a named backup person prevents a scramble.
How do I know if a professional pet sitter is trustworthy?
Ask for references from current clients and actually call them. Ask whether the sitter is insured and bonded (professional sitters should be). Ask how they handle emergencies and what their process is for contacting you. A sitter who asks detailed questions about your pet's routine, health history, and behavioral notes before their first visit is demonstrating genuine engagement with the responsibility. One who takes only basic information and seems to be going through the motions is worth looking at more critically.
