Here's something that stops us cold every July at the Clubhouse: a dog panting hard on a downtown sidewalk at 2 p.m., owner holding a coffee, both of them roasting on asphalt hot enough to fry an egg. Montreal isn't the city it used to be in summer. We average around 11 days above 30 C per season, but by the middle of August 2025 the city had already logged 20 of them, according to meteorologist Anthony Farnell speaking to Global News. If you live in Ville-Marie with a dog and no yard, those numbers are personal. This is how we keep our four-legged members cool, what heat stroke actually looks like, and one summer grooming myth we'd love to bury for good.
Ville-Marie runs hotter than the rest of the island
It isn't your imagination that downtown feels like an oven. The dense central part of the island, along with the low-tree-cover east end, takes the worst of Montreal's urban heat island effect, while leafy boroughs like Outremont stay noticeably cooler. That's the finding from the Urban Environment and Social Inclusion Index analysis covered by Data-Driven EnviroLab. All that concrete and brick soaks up sun all day and breathes it back out at night, which is exactly why the streets around 1800 Sainte-Catherine East can feel ten degrees worse than the forecast says.
For context on what a real heat wave does here: the 2018 event lasted six days, with daily highs averaging 33.7 C, part of southern Quebec's hottest summer in 146 years of records, and it was linked to 86 possibly heat-related excess deaths, per the Environment and Climate Change Canada partner portal ClimateData.ca. Dogs feel that heat even harder than we do, because they can't sweat their way out of it. They've got functional sweat glands in their paw pads and that's about it. Everything else is panting.
The 10-second pavement test could save your dog's paws
Before any summer walk, do this one thing. Hold the back of your hand flat on the sidewalk for ten seconds. If you can't keep it there, your dog can't walk on it. That's the test recommended by Dr. Jerry Klein, the American Kennel Club's Chief Veterinarian, and the physics behind it are brutal: when the air hits 30 C, asphalt can climb to a blistering 57 C. Dr. Klein warns that once you're at 29 C and the ground hasn't had a chance to cool, it may simply be too hot to walk a dog safely.
Honestly, midday walks in July are the thing we wish more Ville-Marie owners would skip. There's no shame in a backyard pee break on grass instead of a full loop on baking pavement. If you do head out, the Ontario Veterinary Medical Association recommends planning walks for the early morning or the evening, when it's cooler and the sun isn't beating straight down. Stick to shade. Plan your route past one of the city's mist stations, play fountains or a tree-lined park, the same cooling spots the City of Montreal points residents toward during heat waves.
If your dog still needs to burn energy, Square Viger dog park right downtown at Saint-André and Saint-Antoine East is open from 7 a.m. to 11 p.m., with separate zones for small and large dogs and a fresh-water fountain with bowls. Hit it at opening or near dusk, not in the blazing middle of the day. Remember the city's rules too: dogs must be leashed (max 1.85 m) everywhere except a dog park, and dogs 20 kg and up also need a harness or halter, per Ville de Montréal.
Know the heat stroke signs before it's an emergency
This is the part that breaks our hearts a little, because it moves fast and a lot of people don't catch it in time. A dog's normal body temperature sits between 38.1 and 39.2 C. Heat stroke sets in when it climbs to 40.5 C or higher, and according to the Cornell University Riney Canine Health Center, many dogs that develop it don't survive. Early recognition is what tips the odds back in your favour.
Watch for heavy panting, drooling, weakness, confusion, vomiting, bloody diarrhea, and in the worst cases seizures or collapse. The OVMA adds muscle twitching and an anxious or dazed look to that list. If you see these signs, this is a true emergency. Cornell's first aid is clear: wet your dog down with cool water and drive straight to a vet with the car's air conditioning blowing right on the dog. Don't wait to see if it passes.
Some dogs are playing on hard mode in the heat. Flat-faced breeds like Pugs, Bulldogs and Boston terriers (yes, our mascot Max keeps a low profile on the hottest days), plus seniors, overweight dogs, thick or dark-coated dogs, and any dog with heart or breathing trouble, all sit at higher risk per Cornell. If that's your dog, be the cautious one. Nobody ever regretted being too careful.
Please don't shave your double-coated dog
We get this request every June, and we understand the logic. The dog looks hot, the coat looks heavy, so off it comes, right? Not with a double coat. Shaving a Husky, a Golden, a Shepherd or a Berner actually works against them. As Dr. Klein explains for the American Kennel Club, that coat is an insulator. Strip it off and you remove the layer that helps regulate temperature, you raise the risk of heat stroke, you expose pink skin to sunburn, and the undercoat grows back faster than the guard hairs, leaving a patchy, often discoloured coat that may never look right again.
What actually helps is the opposite of dramatic. Regular brushing and de-shedding pulls out the dead undercoat so air can move through the coat the way it's designed to. Trimming the fur around the paw pads (where those only sweat glands live) helps too, along with cool baths. That's exactly what our grooming team does for clients all summer. A seasonal de-shed or a Bath & Tidy from $75 keeps a heavy coat working the way nature intended, instead of fighting it. A bath alone starts at $50, and grooming runs Monday to Friday 9 to 6 and Saturday 10 to 5.
The real fix: skip the dangerous midday outing entirely
Here's the honest truth we've landed on after years of Montreal summers. The single best thing for a Ville-Marie dog during a heat wave is to not be outside in it at all during peak hours. Quebec defines extreme heat as three straight days of 31 to 33 C by day and 16 to 20 C at night, and the provincial government's own advice is blunt: don't leave pets in the sun, keep them hydrated, and never leave them alone in a car, per Gouvernement du Québec.
That's the whole reason our climate-controlled daycare shines in July. Instead of a sweltering midday walk you'd rather skip, your dog spends the day playing indoors where it's cool, supervised, and matched by size, then comes home happily tired instead of overheated. Daycare runs Monday to Friday, 7:30 a.m. to 7 p.m. New dogs start with a $25 evaluation, and dogs under 10 lbs have their own calm tiny-dog program. When you'd rather travel together overnight, our in-home boarding from $65 a night (after a meet and greet) keeps your dog in a cool, comfortable home, never a hot kennel.
The hot car warning every Montreal owner needs to hear
We can't write about summer without this one. A parked car is a death trap faster than most people believe. The American Veterinary Medical Association measured it: the inside of a vehicle climbs about 11 C in just ten minutes and roughly 17 C in twenty. Give it a full hour on a mild 21 C day and the cabin can blow past 43 C. Cracking the windows makes no difference, and shade won't save it either. "Just a few minutes" is exactly how it goes wrong.
In Quebec this isn't only dangerous, it's illegal. Leaving an animal to suffer in a hot car is prosecutable under the Animal Welfare and Safety Act, with fines from $1,000 up to $62,500 and as much as 18 months in jail for repeat offenders, per the Montreal SPCA, which runs a 24/7 cruelty hotline at 1-855-711-7575. If you ever see a dog in distress in a parked car, call it. It's also exactly why we offer a climate-controlled dog taxi: pickup and drop-off in a cool vehicle means no dog ever waits in a sweltering car on a daycare or grooming day.
Let's get your dog through the heat the easy way
You don't have to white-knuckle every heat wave alone. Test the pavement, walk at dawn or dusk, learn the heat stroke signs, keep that double coat brushed instead of shaved, and lean on cool indoor days when the city turns into a frying pan. When the forecast climbs, book your dog a cool day at the Clubhouse, call us at (514) 778-CLUB, or drop by 1800 Sainte-Catherine St E in Ville-Marie. Maïka, our three-legged Chief Dog Officer, will be the first to welcome you in from the heat. Got a question first?
