Summer brings warm days, sunshine and lots of fun outdoors – for your dog too. But high temperatures can quickly become a challenge for our four-legged friends. Dogs only sweat through their paws and regulate their body temperature mainly by panting. This makes them more susceptible to overheating. With our tips, you can help your dog survive the summer heat and enjoy the warm months without any worries.

10 tips on how to help your dog stay cool in hot weather

1. Plenty of shade and fresh water

Always make sure there are plenty of shady spots where your dog can retreat to. Especially when out walking, you should make sure that your four-legged friend does not walk in direct sunlight for too long. Fresh, cool water should always be available so that your dog can drink enough and does not become dehydrated.

2. Walks during the cooler hours

Avoid walking in the midday sun when temperatures are at their highest. Early morning or late evening are the best times to be active together and avoid heat stress.

3. Protect their paws

Hot asphalt or sand can burn or irritate your dog's paws. Check the temperature of the ground with your hand before every walk. If it is too hot, choose shady paths or green areas.

4. Cool your dog down in hot weather

Cooling mats or a shady spot with a fresh breeze will help your dog lower its body temperature. A paddling pool or a shady garden pond offer additional bathing fun and refreshment.

5. Recognise symptoms of heat exhaustion

Watch out for warning signs such as heavy panting, salivation, restlessness, weakness, coordination problems, diarrhoea or vomiting. These can indicate overheating or heatstroke and require immediate action. Cool your dog slowly with lukewarm water and seek veterinary assistance immediately if you suspect heatstroke.

6. Adjust your dog's diet

Light, easily digestible food and plenty of fluids support the metabolism in hot weather. Some dogs benefit from additional micronutrients in summer, which care for the skin and coat, and antioxidants, which promote recovery.

A great way to treat your dog on hot days is to make your own dog ice cream. But be careful: it's better to give your dog a little less than too much, so that they can enjoy the cool treat to the fullest without overeating.

7. If your dog does not want to eat: observe and react

Loss of appetite is not unusual, especially in hot weather – many dogs eat less. However, if the bowl remains untouched for a long time or if other symptoms such as listlessness, vomiting or diarrhoea occur, you should seek veterinary advice. Here too, it is better to check once more.

8. Hair care in summer

Regular brushing helps to remove loose hair and improve air circulation on the skin. For long-haired dogs, a professional summer haircut can provide greater comfort.

9. Never leave your dog in the car

Even if you think you are doing something good for them – for example, letting them rest for a while or leaving the window slightly open – a parked car can become dangerously hot in just a few minutes. For dogs, this can quickly become a life-threatening trap. Never leave your four-legged friend unattended in the car in hot weather – not even for a moment.

10. Avoid tight collars

In hot weather, collars can chafe or make it harder for your dog to regulate its body temperature, especially if they are too tight. Make sure your dog can breathe freely and that nothing is cutting into its skin. Lightweight, well-fitting harnesses are often a better choice on hot days.

Why do dogs get diarrhoea in hot weather?

 Heat puts strain on the circulation and can affect the digestive tract. Possible causes:

  • Heat stress: Heat is exhausting for dogs – this can affect the stomach and intestines.

  • Change of water or drinks that are too cold: Cold water from the garden hose or when out and about can irritate the stomach.

  • Spoiled food: Food spoils more quickly at high temperatures – leftovers from walks or found snacks can also be problematic.

  • Less fluid: If your dog drinks too little, this can impair digestion.

  • Cooling down too quickly: Sudden cold, e.g. from an ice bath, puts strain on the circulation – this can also affect the intestines.
