Painting With Pets: How to Repaint Your Home Safely

You can repaint a home with a dog or cat in it, but only with a plan. Choose a low-emission paint, keep the air moving, give your pet a quiet room the crew never enters, and lock away every can, brush and roller, wet or dry. Do those four things and most of the risk goes away.

This guide is for Ontario homeowners, landlords and property managers who are about to hire painters and share the space with animals. At the end, there is a short note for readers who typed this phrase looking for a pet portrait instead.

TL;DR

• Choose products labelled low-emission or low-VOC. Health Canada advises this, and “pet-safe” on a can is not a regulated claim.
• Ingesting oil-based paint, thinner or solvent is the most serious risk for pets, according to VCA Animal Hospitals. Store all materials out of reach.
• Set up a “refuge” room for your pet that is off-limits to workers, with familiar bedding and toys.
• In a pre-1978 house, dried paint chips and dust may contain lead. Deal with that before any sanding starts.
• If your pet gets into paint, call your vet or the Pet Poison Helpline (1-800-213-6680). Do not induce vomiting unless a vet tells you to.

What actually puts pets at risk during a paint job

Most owners worry about the smell. The smell matters, but it is not the biggest danger.

Paint fumes from high-VOC products can irritate a pet’s eyes, nose and throat and cause coughing or laboured breathing. That is the guidance summarized by VCA Animal Hospitals. Cats and small dogs sit close to the floor and spend long hours in one spot, so they are exposed longer. Birds, rabbits and other small animals with delicate airways are a bigger concern still, and your vet can tell you how to keep them safe.

The more serious problems come from swallowing things:

• Oil-based paints, thinners and solvents. These can cause aspiration, severe vomiting, diarrhea and neurological signs such as tremors and seizures.
• Water-based paints. Generally less toxic, but they can still upset the stomach.
• Ethylene glycol. VCA notes that some latex paints contain it, and it causes kidney failure if ingested. Check the product’s safety data sheet.
• Brushes, rollers and tape. Dogs chew them. Taste does not protect a pet, and VCA warns owners not to count on it.

There is also the human side of this. A wet roller left on a drop sheet looks like a toy to a young dog. The ASPCA lists lead paint, nails, screws and wires among the home-repair hazards pets can swallow. A tidy site is a pet-safe site.

Choosing paint that is gentler on animals and people

Start with the label. Health Canada tells households to look for products marked “low emission” or “low VOC”, because paint, varnish and glue release volatile organic compounds, which cause that fresh-paint smell. The Ontario SPCA makes the same point: “pet-safe” is not a regulated term, so do not treat it as a guarantee.

Here is what to compare when you talk to a painter.

Low-VOC does not mean zero risk. A pet that chews a wet roller is still in trouble. But it lowers the background load in the air, which helps every person and animal in the house. If you want the practical contractor side of this, our post on cutting paint fumes during a job walks through it, and our piece on what eco-friendly painting really means explains which green claims are worth paying attention to.

Ventilation: the cheap fix people skip

The Ontario SPCA recommends managing air quality through ventilation, using exhaust fans and your HVAC system, alongside low-emission products. In practice:

1. Open windows in the rooms being painted when weather allows. In an Ontario winter, that may mean short bursts rather than all day.
2. Run bathroom and kitchen exhaust fans.
3. Keep the pet’s refuge room on the far side of the house from the work, with its door closed.
4. Keep ventilating after the crew leaves, because paint continues to give off emissions while it cures.
5. Ask your painter which rooms will be sprayed. Spray finishing puts fine mist in the air and calls for stricter separation than brushing and rolling.

If your pet coughs, wheezes, rubs its eyes or seems lethargic during the project, move it to fresh air and call your vet.

Set up a refuge room before day one

The Ontario SPCA suggests creating a quiet, low-traffic space where workers do not go. Treat it as a real room, not a spare closet.

• Pick a room away from the work zone, ideally with a window you can crack open.
• Put in the bed, blankets with familiar scents, water, a litter box if you have a cat, and a few favourite toys.
• Tape a sign on the door so every worker knows it is closed.
• Try the setup for a night or two before painting starts, so it feels like a normal place to be.
• If your pet gets anxious around strangers, ask a friend to host it for the loudest days, or book a daycare.

Doors are the other weak point. A crew carrying ladders and drop sheets through the front door gives a quick cat a clear path outside. Tell the team which doors stay shut, and agree on one entrance.

Lock up tools, cans and cleanup supplies

Pets are more curious than most owners expect. The practical rule is that every brush, roller and can goes into a sealed container or a locked room when the crew takes a break, not only when the day ends. Dried-out tools can still contain residues, and they are fun to chew.

Ask your painter to do three things:

• Close and seal paint cans whenever they are not being poured.
• Keep thinners and cleaning solvents in a closed, designated area.
• Never leave drop sheets with wet paint pooling on them in a room a pet could reach.

Our painting preparation checklist covers what to clear and confirm with any contractor before work begins. Add your pet’s routine to it.

Floors deserve their own mention, because paws track things. Read our notes on protecting floors while painting and plan a path that keeps wet areas off-limits.

Older homes: lead is the hidden problem

Many paints made before 1978 contain lead. The ASPCA explains that pets can swallow flakes or dust from lead paint once it chips or settles on surfaces. VCA adds that a pet diagnosed with lead poisoning can be a warning that people in the home are at risk too.

If your house in Toronto, Hamilton, Oakville or any older GTA neighbourhood predates 1978, take these steps:

• Ask the contractor how they will handle sanding and scraping on old surfaces, and what they will do about dust.
• Keep pets and children out of the area during prep, and during cleanup.
• Do not dry-sand old paint yourself.
• If you suspect lead, talk to your vet about your pet and your family doctor about your household before work begins.

Prep is where dust is made. That is why a thorough, clean prep process matters more in a home with animals than in one without.

What if your pet gets paint on its fur or swallows some?

Stay calm and act quickly, and contact a professional.

• Swallowed paint, thinner or solvent: Call your vet right away, or reach the Pet Poison Helpline at 1-800-213-6680. VCA lists it as a 24/7 resource for treatment guidance. Do not induce vomiting unless a veterinarian instructs you to, because oil-based products and solvents can be aspirated into the lungs.
• Paint on the coat: VCA’s guidance is to use mild dish soap, or to have the fur clipped by a professional. Never use paint thinner or mineral spirits on a pet.
• Breathing trouble or collapse: Go to an emergency vet. Bring the paint can or a photo of the label and safety data sheet.

Put your vet’s number and the nearest 24-hour emergency clinic on the fridge before the project begins.

A realistic timeline with an animal in the house

The job length shapes how long your pet lives with disruption. Most interior projects run in days, not weeks. See how to plan around three to five days of interior painting for what a typical schedule involves.

A sensible rhythm looks like this:

The handover walk-through matters. A cap or a bit of masking tape on the floor is exactly what a curious pet finds first.

Perspective: what we tell clients who share their home with animals

Most pet questions we hear are about smell, and they are fair. But the bigger issue is process. A clean, organized site matters more than any marketing label on a can.

We look at a pet-household job as three jobs. First, product choice: low-emission options where the finish allows it, discussed openly during the free colour consultation so you know what is going on your walls. Second, containment: clear paths, closed doors, sealed cans, and no tools left lying about at lunchtime. Third, cleanup: when we leave, the floors, trim and corners should be free of debris, and that is as much for your dog’s paws as for your own eyes.

We would rather you tell us at the estimate that you have a nervous cat, a young puppy or a dog that escapes through any open door. That changes how we schedule rooms and which entrance we use. It is a simple conversation, and it prevents the avoidable problems.

Where Sigma Painting fits

If you are repainting in the Greater Toronto Area and want a crew that treats your home carefully, we handle interior painting, kitchen and cabinet painting, stair staining and more. Our work includes prep, cleanup and a free colour consultation, with free, fixed estimates. You can see how we protect homes on our home protection page, or get a number first with the instant quote calculator. When you book, mention your pets so we can plan around them.

For landlords, short-term rentals and multi-unit properties

Pets are not only a homeowner issue. Tenants’ animals, and guests’ animals in short-term rentals, affect how you schedule a repaint.

• Confirm the unit is empty of animals before work, and that the tenant has moved pets out of the building if needed.
• Plan the turnover so fumes clear before the next occupant arrives. Our post on cutting vacancy by a day at tenant turnover covers scheduling.
• Tell new occupants which products were used if they have a pet, in case they ask.

Did you mean pet portraits?

Searching this phrase often turns up artists, not contractors. If you want to commission a painting of your dog or cat, a few pointers from working animal painters:

• Artists commonly start from a high-quality, full-frontal photo. Zann Hemphill suggests side-lighting, which helps map anatomy and texture before the sketch.
• Expect a sketch phase where you can request changes, and expect the piece to look rough partway through before the final details arrive.
• Capturing life in the eyes is widely considered the most important step, as described in a Leisure Painter masterclass on animals.

And about the “80/20 rule” people also ask about: it is a practice approach in which an artist focuses on the key proportions and major light and dark shapes, as Stan Prokopenko explains. It has nothing to do with house painting.

FAQ

Is it safe for my dog or cat to be home while the house is painted?

It is safer for them to be away or in a closed refuge room with a window cracked and the door shut. Fumes can irritate the eyes and airways, and the bigger risk is chewing tools or lapping spilled product. Low-VOC paint and good ventilation reduce the load, but keep animals out of the work area entirely.

How long should pets stay away from freshly painted rooms?

There is no single number that suits every product, so check the label and ask your painter. Keep ventilating after the work ends, because paint keeps releasing emissions as it cures. Let your pet back in only after the smell has cleared and the room has been checked for loose debris.

Is “pet-safe paint” a real category?

Not as a regulated claim. The Ontario SPCA says the term is not regulated, so look for products labelled low-emission or low-VOC and read the safety data sheet. Never assume a label means it is safe to swallow.

What should I do if my pet licked or swallowed paint?

Call your vet or the Pet Poison Helpline at 1-800-213-6680 immediately. Do not make your pet vomit unless a veterinarian tells you to. Have the product name or label ready.
