Heatstroke in Pets: Know the Signs, Act Fast, Save a Life

So as we are now in the second heatwave of the summer and I suspect it won't be the last I wanted to share with you the signs that you dog or cat is starting to suffer from the heat and what ot do about it before you rush to the vets.

It's important to remember that our dogs and cats can struggle with the heat much more quickly than we do. Heatstroke is a life-threatening emergency, but the good news is that it's also largely preventable.

Knowing what to look out for and acting quickly could make all the difference.

What are the signs of heatstroke?

Heatstroke can develop rapidly, especially during warm, humid weather or in poorly ventilated areas. Keep an eye out for these warning signs:

  • Heavy or noisy panting

  • Restlessness or pacing

  • Looking for shade or water

  • Excessive drooling with thick saliva - this is espcially important if you pet is not normally a drooler

  • Bright red gums or tongue

  • Increased heart rate

  • Vomiting or diarrhoea

  • Reluctance to walk or stand up

  • Confusion

  • Weakness or collapse - think floppy doll

  • Seizures - this is now very serious

If your pet is showing any of these signs, don't wait to see if they improve.

What should you do?

The latest veterinary advice is simple:

Cool first. Transport second.

If you suspect your dog or cat has heatstroke:

✅ Immediately cool them with cold water.

✅ Do not wrap them in wet towels, as this can trap heat.

✅ Don't use lukewarm or tepid water.

✅ Once you've started cooling them, contact your vet immediately and follow their advice.

Despite what many people believe, cold water does not cause shock. Rapid cooling gives your pet the best possible chance of recovery. One of the more serious things that can happen with heat stroke is the damage to internal organs as the pet overheats its almost like they are cooking themselves inside.

Which pets are most at risk?

While any pet can suffer from heatstroke, some are particularly vulnerable:

  • Flat-faced breeds such as Pugs, Bulldogs and Persian cats

  • Overweight pets

  • Puppies, kittens and elderly pets

  • Pets with heart or breathing conditions

These pets need extra care during warmer weather.

Prevention is always better than treatment

A few simple precautions can help keep your pet safe:

✔ Walk dogs early in the morning or later in the evening.

✔ Always provide access to fresh drinking water and shade.

✔ Never leave your pet in a parked car—even for a few minutes - I really feel we shou;dn't need to say this but it still happens!

✔ Check pavements before heading out. If it's too hot for your hand, it's too hot for their paws.

✔ Avoid vigorous exercise during the hottest parts of the day.

✔ Don't assume your pet is comfortable just because they aren't showing obvious signs.

✔ If using cooling coats or bandanas, keep them wet so they continue to work effectively, and dont leave them on if your pet is unattended.

Did you know?

Research in the UK found that 74% of canine heatstroke cases were triggered by exercise, not by being left in a hot car. If your dog misses a walk due to the heat it coul just save their life!

Even more concerning, studies show that between 26% and 50% of pets diagnosed with heatstroke do not survive.

These statistics remind us just how serious heatstroke can be—and why prevention and early action are so important.

Keep Your Pets Safe This Summer

At the end of the day, your pet relies on you to recognise when they're struggling.

By knowing the signs, avoiding unnecessary risks and acting quickly if something isn't right, you can help ensure your four-legged family members enjoy a happy, healthy summer.

Stay safe, stay cool, and if you're ever unsure whether your pet may be suffering from heatstroke, contact your vet immediately.

Quite simply for the work I do I wouldn’t be able to have a dog without “Who lets your dog out”…the fact that my dog loves the days she spends with Sara and her team meeting other dogs is a massive bonus…..my puppy literally runs out to meet them when they arrive!

I consider myself lucky to have found such flexible and reliable care for my VIP puppy

Thanks WLYDO

Sara and the team have had our rescue puppy for almost a year, and they have been amazing. Caddie was very nervous around people when we first got her but the team understood that and have been fantastic with her! Could not recommend these guys anymore!
