Training notes
Heat wave rules for dogs
Calgary summers are mostly kind, and then a heat wave arrives and the whole city forgets how to dog. We see it every August: midday walks on shimmering asphalt, patio afternoons with no water bowl, a quick errand with the dog waiting in the car. Here are the rules we follow with every dog in our care, and why each one earns its place.

Pavement and timing
Your hand knows before their paws do.
Asphalt holds heat long after the air cools, which is why an evening walk can still burn pads. Before any walk on pavement, press the back of your hand flat against it and hold. If you want to pull away, your dog's paws will too; they just cannot tell you until the damage is done. Blistered pads are painful, slow to heal, and completely avoidable. When the pavement fails the test, walk on grass, gravel paths or shaded dirt, or trade the walk for training games on the cool side of the house.
Dawn is the honest answer to most heat wave problems. The ground is at its coolest, the sidewalks are quiet, and a reactive or excitable dog gets the bonus of fewer triggers. We move our own training days earlier when the forecast spikes, and we shorten sessions rather than cancel them. Ten focused minutes of heeling at six in the morning beats forty distracted minutes at noon, in any weather. A sniffy shaded loop at dusk closes the day out. The middle of a hot day is for naps, chews and shade. That is not lost training time; rest is part of the routine.

- Walk at dawn or dusk
- Never a parked car
- Water and shade breaks
Cars and short muzzles
The car rule has no exceptions worth naming.
A parked car in summer is an oven with windows, and cracking them does not change that. Quick errands stretch. Lineups happen. The dog has no way out and no way to sweat, and panting stops working fast in a hot, still box. Our rule is simple: if the dog cannot come inside with us, the dog stays home in the cool. We would rather make two trips than gamble on one. If you see a dog locked in a hot car, call for help right away rather than waiting for the owner to appear.
Flat-faced dogs, your Frenchies, pugs and bulldogs, deserve their own paragraph. Those short airways make panting inefficient, so they overheat sooner than their energy suggests, often while still looking delighted. For them we halve everything in a heat wave: half the distance, half the fetch, twice the water. Watch for loud raspy breathing, a tongue wider than usual, or a dog that suddenly lags or lies down; those are stop signs, not quirks. Get to shade, offer cool water, wet the belly and paws, and call your vet if anything looks off. Overreacting costs a walk. Underreacting can cost far more.

Asked and answered
The questions people ask us.
How hot is too hot to walk my dog?
There is no single safe number, because pavement, humidity and the individual dog all move the line. Use the back-of-hand pavement test and your dog's breathing as your gauges. When in doubt, walk at dawn, stick to grass and shade, and keep it short.
Can I leave my dog in the car if I crack the windows?
No. A parked car heats far past the outside temperature even with windows open, and a dog cannot cool itself in still, hot air. If the dog cannot come in with you, leave them home.
What are the signs of heat stroke in dogs?
Heavy relentless panting, thick drool, very red gums, wobbly walking, vomiting or collapse are all emergencies. Move the dog to shade, wet the belly and paws with cool water, and get to a vet immediately. Do not wait to see if it passes.
Do flat-faced breeds like Frenchies need special care in the heat?
Yes. Short airways make panting inefficient, so pugs, Frenchies and bulldogs overheat faster and with less warning than other dogs. Halve their exercise in hot weather, keep water constant, and treat any raspy, laboured breathing as your cue to stop.
