Las Vegas’s Record Heat Wave Arrives This Weekend — Here’s How to Keep Your Dog Safe
Las Vegas is about to do something it has never done before.
An Extreme Heat Warning for nearly all of Southern Nevada is in effect through Sunday night, with temperatures pushing toward 100 degrees — the first triple-digit reading ever recorded in the month of March.
For context, the earliest 100-degree day in Las Vegas history was May 1, 1947. The average high in mid-March is in the low 70s.

That gap, between what this week looks like and what March is supposed to look like, is exactly what makes this weekend dangerous for your dog.
The National Weather Service’s lead forecaster for Las Vegas, Chris Outler, put it plainly: “The dramatic temperature swing has not allowed for acclimation and poses a moderate heat risk.”
He was talking about people. The same logic applies to your dog, and then some.
By mid-August, most local dog owners have quietly recalibrated their routines. They’re out before 6 a.m. or after 8 p.m. They’ve memorized which sidewalks stay shaded and which stretches of asphalt become griddles by 10. Their dogs have had months of gradual heat exposure. The rhythm of a Las Vegas summer, brutal as it is, becomes familiar.
None of that is true right now. Afternoon temperatures this week are running 20 to 30 degrees above normal for mid-March.You may still be walking your dog on a February schedule — mid-morning, the same route you’ve run all winter. Your dog’s paws have not toughened up. If you have a senior dog, a flat-faced breed, or a dog that struggled last July, that struggle is probably not front of mind in mid-March. It should be.
Asphalt in direct Las Vegas sun can hit 160°F when air temperature reaches 100°. The test is simple: press your palm flat to the pavement for seven seconds. If you can’t hold it, your dog can’t walk on it. Concrete runs cooler but still gets dangerous fast. Grass, wherever you can find it, is the right call this weekend.
The rest of the guidance that applies in August applies right now: walk before 8 a.m. or after sunset, carry water and offer it every 15 to 20 minutes, and watch for excessive panting, drooling, stumbling, or a dog that suddenly wants to stop and lie down. Those are not rest breaks. Those are warnings. If your dog shows signs of heat exhaustion, get them into air conditioning immediately and call your vet.
The National Weather Service has issued a Minor to Moderate Heat Risk for the region, noting this is especially important for anyone unprepared for this unprecedented heat.
