Heatstroke

Heatstroke kills pets every year — and it can happen shockingly fast. Dogs and cats can't regulate body temperature like humans can. A few minutes in a hot car or over-exercising on a warm day can cause organ failure and death. Knowing how to recognize and respond to heatstroke can save your pet's life.

Frequently Asked Questions

How hot is too hot for my pet?▼
Risk increases above 80°F (27°C), especially for brachycephalic breeds (flat-faced), thick-coated breeds, and seniors. Cars reach deadly temperatures in minutes — never leave pets in cars. Pavement above 125°F burns paws (ground at 5x air temperature on sunny days).
Why can't I use ice water to cool my pet?▼
Ice water causes blood vessels in the skin to constrict, trapping heat INSIDE the body — the opposite of what you want. Use cool (not cold) water. Wet towels, but change frequently as they quickly heat up.
What temperature is dangerous for pets?▼
Normal: 101-102.5°F (38.3-39.2°C). Heatstroke begins: 104°F (40°C). Life-threatening: 106°F+ (41.1°C). If you don't have a thermometer, cool your pet and get to a vet immediately if symptoms are present.
Do dogs or cats get heatstroke more often?▼
Dogs are more prone — they're more likely to over-exercise, lack sweat glands, and tolerate heat poorly. Brachycephalic dogs (Bulldogs, Pugs) are at highest risk. Cats usually find cool spots but can overheat in trapped spaces or carriers.
