Most of us check the weather before we leave the house. Almost nobody checks the temperature of the ground their dog is about to walk on, and the ground can be much hotter than the air.
Pawmometer exists to close that gap.
Here's how it works. Type in your city, or share your location, and the site reads current weather conditions and estimates surface temperatures for asphalt, concrete, grass, artificial turf, sand, and dirt. It ranks them from most to least dangerous and flags each one for your dog's paws: safe, caution, or avoid. It's free, and it takes a few seconds.
The site also teaches the oldest trick in the book, which needs no technology at all: the 7-second rule. Press the back of your hand against the surface for seven seconds. If it's too hot for your hand, it's too hot for your dog's paws. One writeup of the site notes that asphalt can reach 140°F in direct sun when the air is 87°F, which is hot enough to burn skin.
The story behind it is a good one. According to press coverage (Boing Boing, among others), the site was built by Gregory Paige, who isn't a software developer. By day, he's a product marketer at Circle, the company behind the USDC stablecoin. He made Pawmometer through "vibe coding": he described what he wanted to an AI assistant and let it write the software. (The site itself credits Canina, a dog-gear brand, as its maker.)
It cites its sources, listing the American Kennel Club, Four Paws, Vets Now, a JAMA paper, and a few veterinary and university sources behind its estimates.
It's honest about its limits, too. The site says plainly that these are general estimates, not veterinary advice. Real temperatures vary with shade, surface color, and humidity, and the tool assumes a healthy adult dog with normal paw pads. Dogs with injuries, thin or worn pads, or advanced age can be more sensitive than the thresholds suggest. That's why the hand test is the final word.
It's most useful in summer or anywhere warm. But there's no reason to wait for the next heat wave to bookmark it.
Check the ground before you clip on the leash.
