Hot Weather & Car Safety Advice for Dogs

Hot Weather & Car Safety Advice for Dogs

With the hope of better weather on the way, many pet owners may be excited to plan some day trips or holidays with their dog. However, a car journey on a warm day could put your dog at risk of heatstroke if preparations aren’t made. PDSA’s Pet Store has everything you need to make sure your dog stays happy, healthy, and safe whilst they’re on their adventures.

Heatstroke is a very serious condition that can progress very quickly, and in severe cases, can cause seizures, organ damage, and even death. Most cases of heatstroke in dogs occur because of over-exercising in warm weather, but it can also be caused by being trapped somewhere hot, or in some circumstances, just sitting somewhere warm – like a car. Visit our Pet Health Hub page for more information, and first aid advice for heatstroke.

Preventing Heatstroke during Travel

Avoid travelling with your dog in a car when it’s hot

If a journey is absolutely necessary, try to avoid travel with your dog in the hottest part of the day. Make sure the car is cool before they get in and they can access fresh drinking water during the journey. The Road Refresher Bowl is a non-spill pet bowl that has a floating plate inside which allows free access to water but prevents spills when braking or cornering. It’s genius!

Ensure that air is flowing – use your cars air con or have the windows open. These window vent guards from PetGear are great as it keeps your dog safe whilst keeping the car ventilated. Be mindful that air con may not reach or be less effective in the back of the car and the boot.

Cooling mats can be useful when travelling on warm days like this All For Paws Papaya Cooling Mat.

Walk them when it’s cool

Avoid walking your dog in the hottest part of the day, instead take them out in the early morning/evening when it’s cool. Bear this in mind during long travel as your dog will need to have exercise and toileting breaks.

Get them wet on warm days

If your dog likes a swim, try and plan a stop along the way with a safe swimming area for them to get wet, exercise, and cool down.

Use a harness instead of a collar

Attaching a lead to a harness will put less pressure on your dog’s throat, making it easier for them to pant and cool down. This is especially important if your dog has breathing problems or is brachycephalic (flat-faced). Remember to keep your dog’s collar on even if you are using a harness to walk them – it’s a legal requirement.

We have a wide range of dog collars, leads, and harnesses available on the Pet Store.

Secure your dog in the car

Your dog will also need to be suitably secured in the car during travel. For dogs travelling in the back of the car, we recommend the Car Safe Crash Tested Harness which uses your car’s seat belt to keep them safe, comfortable, and secure. It can also be used as a walking harness during breaks and stops.

For dogs travelling in the boot consider this Henry Wag Car Boot and Bumper Protector which not only protects your boot but keeps your dog comfortable during their journey.

Never walk your dog on a hot surface

If you can comfortably place the palm of your hand on it for 7 seconds it’s okay – sand, artificial grass, and tarmac get especially hot.

Never leave your dog in a car

Not even for a few minutes, with the windows open, or in the shade. This means you will need to find stops and service stations that are dog friendly.

Keep your dog a healthy weight

Overweight dogs find it more difficult to stay cool.

Consider having your dog clipped

Especially in the warmer months if they have a heavy coat. Brushing your dog’s fur can also help.
