Caring for a Senior Pet During a House Sit (2026 Guide)

Home > Blog > Caring for a Senior Pet During a House Sit

Caring for a senior pet during a house sit is mostly about adjusting your pace, not managing a medical situation. Across six sits with older dogs and cats, from a seven-year-old Golden Retriever to a thirteen-year-old Labrador, we've found that the vast majority of "senior pet" sits just mean slower walks, a bit more help getting around, and sticking closely to a medication or feeding schedule. The pets themselves are usually happy, loved, and full of personality. The job is simply to meet them where they are.

Older pets get overlooked in a lot of house sitting advice, which tends to focus on puppies, high-energy dogs, or emergencies. But a meaningful number of sits involve an animal well into its senior years, and the day-to-day reality of that is different enough from a younger pet's sit that it's worth covering properly.

If you're using Trusted House Sitters to find sits, our 25% discount code is worth grabbing regardless of what kind of pet you end up caring for.

This guide covers what actually changes, what to ask before you accept a sit with an older pet, and where the line is between "senior pet care" and something more serious.

What "Senior Pet" Actually Means for a House Sitter

A senior pet is not automatically a medically complex one. Of the six older animals we've cared for across our sits, none had a diagnosed condition beyond general age-related slowing down. They were frail, sometimes slow to get up, occasionally set in very particular routines. But they were also, in every case, happy, affectionate, and clearly well looked after by their owners.

This distinction matters because it's easy to feel anxious about accepting a sit with an older pet, imagining you'll need to manage something medically difficult. In our experience, that's rarely the case. Most senior pet sits are simply a request to slow down, be patient, and follow a routine closely.

The animals themselves are often lower-maintenance in some ways than a young, high-energy dog, precisely because they're not trying to bolt after every squirrel or chew through a door.

Six Sits, Six Older Animals: What We've Learned

A seven-year-old Golden Retriever on one of our early sits taught us that "senior" for a large breed can start well before double digits. He was gentle, a little stiff getting up in the mornings, and happiest on a slow, steady walk rather than anything strenuous.

In Manosque, May, the ten-year-old mixed breed we've written about elsewhere for her separation anxiety, was also noticeably slower than a younger dog would be, which actually made the anxiety easier to manage. Short absences were fine as long as we built up to them gradually.

In Kefalonia, alongside the cat situation we've covered in our France region guide, there was also a seven-year-old mixed breed dog who needed nothing more than a consistent routine and a comfortable spot to nap through the heat of the day.

Our sit in Cortona involved a thirteen-year-old Labrador, Teddy, who by most measures should have been the frailest animal on this list. He wasn't. Teddy climbed three flights of stairs every night to sleep in our room, without fail, for the entire sit. Age doesn't always mean what you'd expect. Some older animals slow down considerably. Others simply keep going.

In Lullin, the two outdoor cats we cared for, Muscaton and Piton, were both eleven years old and about as independent as any cat we've met, elderly or otherwise. They came and went on their own schedule and needed almost nothing from us beyond food and the occasional scratch behind the ears.

And in Lismore, there was the seventeen-year-old chihuahua we've written about in detail in our guide on what to do if a pet dies during a house sit, since that sit sits closer to the edge of what this article covers. If you're caring for a pet whose owner has explicitly acknowledged they could pass away at any time, that guide is the one to read alongside this one.

The Physical Adjustments: Mobility, Pace, and Bathroom Breaks

The single biggest change with an older pet is pace, and it affects almost everything else.

Walks tend to be shorter and more frequent rather than one or two long outings a day. An older dog may need to go out more often for bathroom breaks, sometimes with less warning than a younger dog would give, so staying alert to their cues matters more than it would otherwise.

Stairs, getting in and out of cars, and jumping onto furniture can all become genuinely difficult for an older animal, even one that seems otherwise healthy. Carrying a small dog, using a ramp if one is provided, or simply allowing extra time for a larger dog to navigate steps is often all that's needed. This isn't a medical intervention. It's just patience.

Non-slip surfaces matter more for older pets, particularly on tile or hardwood floors where an unsteady animal can slip. If a homeowner mentions their pet has started struggling with certain surfaces, take that seriously and adjust where the pet spends time if you can.

Medication and Health Routines

Consistency is the single most important thing you can offer an older pet, more than anything else on this list.

Many senior pets are on some form of ongoing medication, whether that's a joint supplement, arthritis medication, or something for a chronic but manageable condition.

Getting the timing right matters more with older animals, since their systems are often less able to compensate for an irregular schedule. Our guide to giving a pet medication during a house sit covers the practical mechanics of this in detail, but the core principle is simple: get a clear written schedule from the homeowner before they leave, and stick to it precisely.

If a pet's health needs are genuinely complex, more than a simple daily supplement or medication, ask specific questions on the video call before you accept the sit rather than discovering the full scope once you arrive. Our guide to what to ask a homeowner before you house sit has the full list of questions worth covering.

Diet and Feeding Adjustments

Older pets often eat differently than younger ones, and it's worth understanding the specific routine rather than assuming a standard feeding schedule applies.

Senior-specific food, smaller and more frequent meals, or a reduced appetite are all common in older animals. Some senior pets also have specific dietary restrictions tied to weight management or a health condition. Whatever the homeowner tells you about feeding, follow it precisely rather than adjusting portions based on what seems reasonable to you. An older animal's weight and digestion can be more sensitive to change than a younger pet's.

What to Ask Before You Accept a Senior Pet Sit

The right questions before the sit prevent almost every problem that could come up during it.

Ask specifically about medication and health requirements: what they're on, the exact timing, and what happens if a dose is missed or delayed. Ask about the homeowner's wishes and expectations for the pet's routine, since an owner who's lived with an aging pet for years often has strong, specific preferences about how their day should go. Ask what's off-limits: too much exercise, certain foods, specific furniture, or activities the pet used to enjoy but can no longer safely manage. And ask directly what the homeowner would want you to do if the pet's condition changes noticeably during the sit, even if you don't expect it to.

These aren't uncomfortable questions to ask. Every homeowner we've spoken to about an older pet has appreciated being asked, because it shows you're taking their pet's needs seriously rather than assuming a senior pet sit is the same as any other.

Have you cared for an older pet with a specific routine that worked well? We'd genuinely like to hear about it in the comments, since every sit teaches us something slightly different.

When to Read Our Guide on Pet Death Instead

This article covers day-to-day senior pet care: the pace, the routine, the small adjustments that make an older animal's life easier during your sit. It is not about end-of-life care or what to do if a pet passes away while you're responsible for them.

If a homeowner tells you upfront that their pet could realistically pass away during your sit, if the animal has a serious diagnosed condition, or if you want to be fully prepared for the more difficult scenario regardless of how likely it seems, our complete guide on what to do if a pet dies during a house sit covers that specifically, including how to handle the call to the homeowner, what to do with the pet, and the grief that comes with it for sitters too. The two guides work best read together if you're taking on a sit with a genuinely frail or elderly animal.

The Emotional Side: Loving an Animal You Know Won't Be Around Forever

There's something particular about caring for an older pet that's different from a younger one, and it's worth naming honestly.

You know, in a way you don't with a younger animal, that your time with this particular pet is likely limited. Teddy climbing those stairs every night, Muscaton and Piton doing their own thing in the Alpine sunshine, the Golden Retriever's slow, steady walks: these moments carry a bit more weight when you're aware of where the animal is in its life. That's not a reason to feel heavy about accepting these sits. If anything, it's part of what makes them meaningful, and part of why house sitting is worth it in the first place, being present for the parts of an animal's life that its own family doesn't always get to see day to day.

Bottom Line

Caring for a senior pet during a house sit is, in the overwhelming majority of cases, simply about adjusting your pace and following a routine closely. Slower walks, help with stairs, consistent medication timing, and a bit more patience cover most of what you'll actually need. Ask the right questions before you accept the sit, take the homeowner's specific wishes seriously, and treat the animal's age as a reason for gentleness rather than anxiety. If a sit does involve something more serious, our guide on pet death during a sit picks up exactly where this one leaves off.

Frequently Asked Questions

• What counts as a "senior" pet for house sitting purposes?

  It varies by species and breed. Large dog breeds are often considered senior from around 7 years old, while smaller dogs and cats may not show significant age-related changes until 10 or later. The more useful marker than a specific age is whether the homeowner describes noticeable slowing down, mobility issues, or an established medication routine.

• Do I need special experience to sit for an older pet?

  No specific certification or experience is required, but patience and attentiveness matter more than with a younger animal. Asking detailed questions before the sit and following the homeowner's routine precisely will cover the vast majority of what's needed.

• What if the older pet's health changes during the sit?

  Contact the homeowner immediately to describe what you're observing, even if it seems minor. If the change seems urgent, contact the vet using the details provided in your pre-sit preparation. If the situation becomes serious, our guide on what to do if a pet dies during a house sit covers the full process.

• Should I ask about a pet's age before accepting a sit?

  Yes, along with general health and routine questions. It's a normal part of understanding what a sit actually involves, not an uncomfortable topic. Most homeowners appreciate a sitter who asks thoughtful questions about their pet's specific needs.

• Are older pets more work than younger ones?

  Not necessarily more work, just different work. Older pets often need less physical exercise and are less likely to get into mischief, but they may need more frequent bathroom breaks, help with mobility, and closer attention to medication timing.
