Warm weather might seem like the perfect excuse for long walks and garden play, but when the temperature rises it can be risky for our pets, especially dogs and cats who can’t cool down like we do. Here’s how to help them stay safe, happy and healthy in the heat.
Why heat is harder on pets
Unlike humans, dogs and cats don’t sweat to regulate their body temperature. Dogs mainly rely on panting while cats prefer to stay still in cool spots. That means hot weather can quickly become dangerous, especially for flat-faced pets like pugs, bulldogs and Persians, as well as older animals, young kittens or puppies, overweight pets and thick-coated breeds. Even mild temperatures can cause issues for them.
What temperature is safe for walkies
As a general rule, under 19°C is fine for most dogs. Between 20 and 23°C you’ll want to take extra care, especially with more vulnerable breeds. Anything 24°C and above is best avoided. For cats, limit outdoor time during the hottest part of the day and make sure there is always a cool shaded space available.

Pavement check: the five-second rule
If you can’t comfortably hold the back of your hand on the pavement for five seconds, it’s too hot for your dog’s paws. Burnt pads are painful and may need vet treatment.
When should you walk your dog?
Stick to early mornings or late evenings when the sun is lower and the ground is cooler. Midday walks can quickly lead to overheating and are best avoided completely.
Too warm to walk? Try these instead
If it’s too hot to head out, you can still keep your pet active and entertained:
- Puzzle feeders or lick mats to keep their mind busy
- Shady sniff sessions in the garden
- Frozen treats made with water or broth
- Cooling mats or shallow paddling if your pet enjoys water
Mental stimulation can be just as effective as physical exercise.

Fleas and ticks love summer too
Warm weather is ideal for parasites like fleas and ticks. They’re more active and often picked up after time outside, especially in grassy or wooded areas. Keeping your pet protected with regular treatment is essential throughout summer. VetBox makes it easy by delivering it straight to your door each month so you never miss a dose.
Heatstroke: what to watch for
Act fast if you notice any of these signs:
- Excessive panting or drooling
- Bright red gums or tongue
- Vomiting, lethargy or wobbliness
- Collapse
Heatstroke is an emergency, so contact your vet immediately.
Quick recap
Keep walks to cooler times of day, avoid hot pavements, offer plenty of shade and water, and stay on top of parasite protection. With a bit of planning, your pets can enjoy the summer safely and comfortably.
