Pet Heat Safety: How to Protect Pets During UK Heatwaves

10th July 2025

The British summer of 2025 has been one of the hottest on record, with repeated heatwaves and soaring temperatures well above the seasonal average. As the hot weather continues across the UK, it’s essential to prioritise pet safety in extreme heat.

While many of us are making the most of the sunshine or doing our best to stay cool indoors, our pets can find it much harder to regulate their body temperature and are at serious risk of heat-related illness. Knowing how to keep your dog, cat or small pet safe during a UK heatwave is more important than ever.

 

Hydration is More Important Than Ever

In this heat, pets can become dehydrated quickly. Always make sure they have access to fresh, cool water – indoors and out. If you’re heading out, pack a travel water bottle and collapsible bowl so they can stay hydrated on the go.

For cats, encouraging them to stay hydrated is especially important during hot weather, and a cat water fountain can make a big difference. Many cats naturally prefer running water, as it’s instinctively perceived to be fresher and safer than stagnant sources. The gentle movement and sound of a fountain can attract their attention and entice them to drink more often, helping to support kidney function, reduce urinary tract issues and overall health.

You could even pop a few ice cubes into their bowl at home to help keep the water cool or offer frozen treats such as frozen blueberries or raspberries.

 

 Watch Out for Overheating and Heatstroke

The risk of heatstroke rises sharply in extreme temperatures. Symptoms can include:

  • Heavy panting
  • Excessive drooling
  • Lethargy or unsteadiness
  • Vomiting or collapse

To prevent this:

  • Avoid walking pets during the hottest parts of the day (typically between 11am and 4pm).
  • Opt for early morning or late evening strolls when it’s cooler.
  • Always ensure they have access to shade and a cool place to rest.

If you’re booked in for our dog walking services, your local Petpals team will get in touch if they determine it’s too hot for a safe walk. They’ll offer suitable alternatives, such as a garden visit, to ensure your dog still gets care and attention while staying cool.

 

Never Leave Pets in Hot Cars

Even during a short stop, temperatures inside a vehicle can skyrocket within minutes – far exceeding the temperature outside. Cracked windows make little difference. The message is simple: never leave your pet in a parked car during hot weather, not even for a minute.

 

Paw Protection – Pavements Can Burn

Tarmac, pavements and sand can become dangerously hot and cause painful burns to your pet’s paw pads. Try the five-second test: if you can’t hold your hand on the surface for five seconds, it’s too hot for paws. Choose shaded or grassy walking routes, or invest in protective booties if your pet tolerates them.

 

Cooling Options to Help Beat the Heat

Create cooling opportunities around the home or garden:

  • Set up a shallow paddling pool for dogs.
  • Provide cooling mats or pet-safe cooling coats.
  • Make shaded outdoor areas with canopies or parasols.
  • Use fans around the house to create airflow.
  • Try pet-friendly frozen treats – the Blue Cross has lovely recipes for both dogs and cats.

 

Don’t Forget Sunburn

Pets with light or sparse coats – including white dogs, cats, and rabbits – are especially vulnerable to sunburn. Areas such as the ears, nose, and belly are most at risk, so if your pet enjoys lounging in the sun, apply a pet-safe sunscreen (never use human products) to these exposed spots. For outdoor rabbits or hutched pets, it’s also vital to create plenty of shade using covers, umbrellas, or placing their hutch in a sheltered area to protect them from direct sunlight and overheating. 

 

Diet and Grooming Adjustments

Your pet’s dietary needs may change slightly in hot weather – they may eat less or require different nutrients. Speak with your vet about any adjustments. Regular grooming is also helpful to remove excess fur, but don’t be tempted to shave them without professional advice, as some coats help regulate body temperature.

 

Water Activities – Supervision is Key

If your dog enjoys swimming, it can be a fantastic way to help them stay cool and active during hot weather. Water-based activities not only provide relief from the heat but also offer excellent low-impact exercise, especially for older dogs or those with joint issues. Always supervise your dog closely around water, whether it’s a paddling pool, river, or the sea, and consider using a well-fitted pet life jacket for added safety—especially in deeper or moving water. After swimming, be sure to rinse off any chlorine, salt, or debris to protect their skin and coat, and gently dry their ears to help prevent infections. 

 

Know the Signs of Heatstroke – and Act Fast

Recognising heatstroke quickly can save your pet’s life. If you suspect your pet is overheating:

1. Move them into a shaded or cool area immediately.

2. Offer cold water.

3. Dampen their paws and body with cold water.

4. NEVER cover them with cold wet towels, this prevents heat from escaping.

5. Use a fan to circulate cool air.

6. Contact your vet straight away, don’t delay even if they are showing signs of improving.


Stay Safe and Enjoy the Sunshine

With the UK in the grip of a heatwave, taking these extra precautions will help your pets stay happy and healthy. Keep routines flexible, watch closely for signs of discomfort, and prioritise water, shade and rest.
