Walk-safety weather, from your dog's point of view.

Air temperature only tells half the story. Asphalt in direct sun can run far hotter than the forecast, and a bright afternoon can push UV past what a short-coated dog should be out in. CoolTail puts all three numbers on one card — temperature, UV index and estimated pavement heat — and tells you plainly whether right now is in range.

Set the comfort limits yourself, because a husky and a greyhound don't agree on much. CoolTail then flags the best windows to head out and reminds you when it's time.

What it does

Three numbers that decide the walk.

CoolTail reads live hourly forecast data, estimates surface heat, and compares everything to the limits you set.

Pavement heat

An estimate of how hot the ground actually is — the number that matters to bare paws, not the one on the news.

UV index

Graded low to extreme, so pale noses and thin coats get shade when the sun is doing too much.

In range, or not

One unambiguous verdict on the current conditions instead of three numbers you have to interpret.

Best outdoor times

CoolTail scans the hours ahead and surfaces the windows that clear every one of your limits.

Walk reminders

Recurring nudges for your dog's outdoor time, with an early warning to check conditions before you grab the leash.

Tuned to your pet

Set temperature, pavement and UV thresholds that match your dog's breed, coat, age or sensitivity.

CoolTail is a planning aid, not veterinary advice. Pavement temperature is an estimate derived from forecast conditions — always check the ground with your hand before a walk, and talk to your vet about what's right for your dog.
