Article updated on: February 2026
π QUICK FACTS:
The biggest red flag: A sitter who avoids the video call. Non-negotiable, full stop
Most overlooked red flag: Five-star reviews that say nothing about physical fitness for high-energy dogs
The application message: Accounts for roughly 70% of the yes. If it reads like a holiday wishlist, that is your answer.
Yellow vs red flags: Slow replies are yellow: worth monitoring. No call, holiday language, defensive review responses: those are red.
What the community reports most: Uninvited guests, dirty properties, undisclosed damage, and sitters who respond badly when called out on it
We are house sitters. We have done 15+ sits across 9 countries, and along the way we have spoken with a lot of homeowners: before sits, during handovers, and on video calls where they were happy to talk openly once they trusted us. One thing comes up again and again: homeowners who have been let down by a previous sitter, and the pattern of warning signs they missed.
This article is our attempt to put that pattern into writing. Not from the outside looking in, but from the perspective of people who are on the same platforms, reading the same profiles, and understanding exactly how the system can be gamed.
If you are a homeowner using TrustedHouseSitters or a similar platform to find someone to care for your pets, these are the things we would tell you to watch for.

The Application Message Is Where It Starts
Most homeowners receive applications that focus on what the sitter wants. The pool. The location. The chance to explore a new country. Some of these messages barely mention the pets. That is the first red flag: a sitter who is clearly thinking about their holiday, not your animals.
A strong application addresses your specific situation. It mentions the pets by name if you have listed them. It shows the sitter has read the listing. It explains what they will do for you, not just what they are hoping to get out of it. In our experience, getting that message right accounts for roughly 70% of a yes. The profile and photos are the remaining 30%.
When we applied for our first sit with no reviews, we knew we had nothing to lean on. So we focused entirely on the homeowner's situation: what we would bring, how we would care for the property, what our daily routine looked like. We sold ourselves by making the homeowner's decision easier, not by listing our own preferences. If an applicant cannot do that with zero reviews, they probably cannot do it with twenty either.
Good vs. Bad: What an Application Message Actually Looks Like
| β Red Flag Message | β Strong Message |
|---|---|
| "Hi! We love travelling and are looking for a sit in your beautiful area. We have stayed in many houses before and love all animals." | "Hi, we noticed Bella is a 4-year-old Labrador who needs two walks a day. We have cared for three Labradors across our last five sits and are comfortable with their energy levels and routines." |
| "We would love to use your home as a base to explore the region." | "We work remotely and keep a consistent daily schedule, which works well for dogs who need routine." |
| "We are very reliable and responsible people." | "Our last homeowner in Cortona left us a detailed Welcome Guide and we followed every instruction." |
The difference is specificity. A bad message could have been sent to anyone. A good one could only have been sent to you.
For more on what makes a reliable sitter stand out, see our guide to what house sitters actually do.
What a Good Profile Looks Like, and What a Red Flag Looks Like
A sitter's profile is their first impression. When we look at other sitters' profiles, which we do occasionally out of curiosity, the difference between a strong profile and a weak one is usually obvious within thirty seconds.
Red flags in a profile:
Incomplete or mostly blank. No photos of themselves or their work. A sitter who cannot be bothered to fill in their profile is showing you something.
Photos that are clearly pulled from a phone gallery rather than showing them with animals. A sitter who loves pets will have photos with pets.
A bio that reads like a wishlist. "Looking for sits in warm climates with a pool and good Wi-Fi." This is not a red flag on its own, but if the entire profile is written this way, it tells you the sitter is thinking about themselves.
No verification badges. Most platforms allow ID verification, and reference letters. A sitter who has skipped all of these has decided those things are not worth their time.
The profile and the application message should complement each other. If the message is strong but the profile is vague, something does not add up. The opposite is also true.

Red Flag vs. Yellow Flag: A Quick Reference
Not every warning sign means the same thing. Some are dealbreakers, others are worth monitoring.
| Signal | Warning Level | Why It Matters |
|---|---|---|
| No video call | π΄ Red Flag | Non-negotiable. If they won't show their face, they should not be in your home. |
| "Holiday" language in the application | π΄ Red Flag | Focus is on the pool or location, not the pet's welfare. |
| No response to pet-specific questions | π΄ Red Flag | Shows they have not read the listing or do not care about the details. |
| Defensive response to a negative review | π΄ Red Flag | Tells you exactly how they handle difficulty. |
| Slow initial reply | π‘ Yellow Flag | Could be travelling or in a different timezone. Monitor for consistency. |
| No animal photos in profile | π‘ Yellow Flag | They might be new, but it shows limited effort in demonstrating what they care about. |
| No reviews | π‘ Yellow Flag | Not a dealbreaker on its own. The rest of the application needs to compensate. |
| Vague on dates or logistics | π‘ Yellow Flag | Worth clarifying before approving. Vagueness usually means something is unsettled. |
A single yellow flag is rarely a reason to reject an application. A cluster of them, or any red flag alongside yellow ones, is worth taking seriously.
The "Physical Fit" Gap: Why 5-Star Reviews Can Be Deceptive
This one gets talked about less, but we have heard it directly from homeowners.
In Belgium, when we arrived for a sit, the homeowner visibly relaxed when they saw us step out of the car. They told us the previous sitters who had applied had glowing five-star reviews. Nothing in those reviews suggested a problem. What the reviews did not mention was that one of the applicants could barely walk. The sit involved an energetic Labrador that needed to run two or three times a day. The reviews told the homeowner nothing about whether the sitter was physically capable of the job.
This is not about judging anyone. It is about fit. A sitter's experience needs to match the specific requirements of your animals. An elderly cat and a border collie are not the same commitment. Ask directly on the video call: what does your typical day of exercise with a dog look like? How far do you usually walk? What is your experience with high-energy breeds?
A sitter who cannot answer those questions concretely, or who seems vague about what the daily routine would look like, is worth pressing further.
Physical Fit Checklist: Questions to Ask Before You Approve
| Question to Ask | What a Good Answer Looks Like |
|---|---|
| How many kilometres do you typically walk per day? | A specific number, not "as much as needed" |
| What breeds have you cared for before? | Named breeds, not just "all dogs" |
| How do you handle a dog that pulls on the lead? | A method, not a shrug |
| Are you comfortable with twice-daily runs? | A yes with context, not just a yes |
| Do you have any physical limitations we should know about? | An open, honest answer either way |

Communication Patterns Before the Sit
How a sitter communicates before the sit is a preview of how they will communicate during it.
Slow replies are a yellow flag, not always a red one. People are busy. But if replies consistently take more than 24 hours, if messages are one word, or if the sitter seems disengaged in the early conversation, that is worth noticing. Imagine trying to reach them at midnight when something goes wrong with your dog.
More telling than speed is substance. Does the sitter ask questions about your pets? Do they show curiosity about the routine, the quirks, the things that matter to you? A sitter who shows no interest in learning about your animals before the sit is unlikely to be attentive during it.
The sitter should also be clear and specific. Vague answers to direct questions (when do you arrive, what does a typical day look like, how do you handle a sick animal) are worth following up on. A sitter who cannot give you a straight answer before the sit begins is showing you a communication style you will be stuck with for the duration.
What the Video Call Reveals
The video call is the most useful tool you have, and a sitter who avoids it is an immediate red flag.
We do every call over WhatsApp. It is simple, free, and lets both sides get a real sense of who they are dealing with. We have learned as much about homeowners on those calls as they have learned about us. That cuts both ways: a good call is reassuring for everyone, and a bad one is valuable information.
We once applied for a month-long sit in Italy. A wonderful property, great dog, pool, outdoor shower. Genuinely one of the more appealing listings we had seen. But on the call, the homeowner was evasive about the dates in a way that felt odd. We asked him not to approve the sit and to come back to us when he had clearer information. We kept looking in the meantime. Eventually we found something better. His response when we let him know was an incoherent message that seemed like it had been written in a very different state of mind. We had sensed something was off early, and we were glad we listened to it.
That story is about a homeowner, but the principle applies equally to sitters. The video call is where the real picture emerges. Watch for sitters who seem distracted, give inconsistent answers, or appear to be pitching rather than genuinely engaging. The sitter who is already thinking about how to get out of things will show you that on the call.
During the call, ask specific questions about the pet care. Walk them through your routine. A sitter who is listening will take notes, ask follow-up questions, or volunteer relevant experience. A sitter who nods along and gives generic reassurances is not really engaging. Our house sitting video call guide covers exactly what to ask and what the answers reveal.

Reviews, and How Sitters Respond to Them
TrustedHouseSitters reports that 98% of sits are reviewed positively. In our own experience, roughly 90% of sits are great, around 5% are genuinely exceptional, and the last 5% are less desirable. A sitter with a long string of positive reviews is not unusual. It is the norm, not a guarantee.
This means you need to read beyond the star rating.
A lack of reviews is not automatically a red flag. Everyone starts with zero. We did. When a sitter has no reviews, the rest of their application needs to work harder: detailed profile, strong first message, full willingness to do a video call. A sitter with no reviews who also resists a call? That combination is a red flag.
For sitters who do have reviews, read the negative ones carefully. Not for what happened, but for how the sitter responded. A response that is defensive, emotional, or attempts to discredit the homeowner tells you a great deal about how that sitter handles difficulty. Our advice, and something we cover in depth in our guide to responding to negative reviews: take a breath, remove the emotion, and respond as if a future homeowner is reading it. Because they are.
A sitter who responds to a one-star review with accusations or sarcasm is showing you exactly how they behave when things go wrong. That is the version of them you will be dealing with if your sit has a difficult moment.
Under TrustedHouseSitters' current double-blind review system, neither party can see the other's review until both have been submitted or the 14-day window has closed. This makes the reviews themselves more honest than they used to be. But the responses to reviews are still public, and still revealing.
The Welcome Tour and the First Day
If you are doing an in-person handover, the welcome tour is your last chance to observe the sitter before you leave.
A good sitter asks questions during the tour. They want to know where the vet is, what the emergency contacts are, how the heating works. They are trying to understand the property so they can manage it without needing to call you. A sitter who nods through everything and seems eager for you to leave is worth reconsidering.
The other thing to watch is how your pet reacts. Not on a video screen (we do not think animals can reliably sense a person through a phone), but in person, the first meeting tells you something. A pet that is genuinely fearful or avoidant after a reasonable amount of time is giving you information. A sitter who dismisses this or tries to rush the introduction is not reading the situation correctly.
The Cortona homeowners we sat for gave us a detailed Welcome Guide: emergency contacts at the top, medication routines pre-portioned and labelled, restaurant recommendations included. Everything was considered. A homeowner like that attracts a certain kind of sitter, because the quality of the listing signals what kind of experience this will be. If you want a thorough, attentive sitter, being a thorough, attentive homeowner is a good start. Our guide to preparing for a house sitter goes into this in detail.
What the House Sitting Community Reports
Beyond our personal experience, community accounts on forums and platforms regularly surface the same patterns: sitters bringing uninvited guests to sits, leaving properties in poor condition, causing damage and not disclosing it. These are the sits that end in disputes and negative reviews.
Many of those disputes, from what we have read across the community, come down to strong opinions clashing. A sitter with very fixed ideas about how things should be done, and who is not willing to adapt to a homeowner's preferences, can create friction in sits that might otherwise have gone fine. That personality type is hard to spot in advance, but the video call and the message thread often give hints. A sitter who corrects or challenges you before the sit has even started.

FAQ
Is it a red flag if a pet sitter has no reviews?
Not on its own. Everyone starts with zero reviews, including us. A sitter with no reviews should have a detailed profile, a strong and specific application message, and full willingness to do a video call. If any of those three are missing, the combination becomes a concern.
How can you tell if a sitter actually reads your listing?
The application message will tell you. A sitter who has read your listing will mention specific details: the pet's name, the breed, something in the description that stood out to them. A generic message that could have been sent to fifty listings is a red flag.
What should I ask on the video call to filter out unreliable sitters?
Ask about the daily routine: how many walks, what time, how long. Ask about a scenario: "what would you do if the dog refused to eat?" Ask about their experience with the specific type of animal you have. A reliable sitter will have considered answers. A sitter who seems to be improvising or giving vague reassurances is worth pressing further. See our house sitting video call guide for more.
Is an evasive answer about dates or logistics a red flag?
Yes. Vagueness about something as basic as confirmed arrival and departure dates usually means something is not settled on their end. A sitter who cannot commit to specifics before the sit is confirmed may be juggling multiple sits or not fully organised. Get clarity before you approve.
How seriously should I take a sitter's response to a negative review?
Very seriously. The review itself tells you what happened once. The response tells you how the sitter handles conflict, criticism, and accountability. A measured response that takes some responsibility and focuses on resolution is a good sign. A defensive one that tries to discredit the homeowner is a pattern you do not want to import into your home.
What if the sitter's profile looks great but something still feels off after the call?
Trust that feeling. In our experience, the small signals that seem hard to articulate often turn out to be right. You do not need to explain a gut feeling to anyone. There will be other sitters, and the cost of one bad sit, for your pets, for your property, for your peace of mind while you are away, is not worth talking yourself out of it.
