As the country finally basks in some summer sunshine, Dogs Trust Newbury has issued a reminder to dog owners that there is no safe amount of time to leave dogs alone in a car during the hot weather – even a few minutes could prove to be fatal.

The nation’s largest dog welfare charity is warning owners that the temperature inside a car could rise to dangerously high levels in just a few minutes, leading to any dogs inside the car suffering with heatstroke. In some cases, heatstroke can lead to the death of the dog.  

Dogs Trust is also reminding owners that exercising dogs in warm weather can lead to severe health problems in our canine companions – three quarters of heat stroke cases are triggered by exercise – and even short walks in the heat should be avoided

Dogs can’t regulate their body heat in the same way as humans, and dogs can overheat in all temperatures, so extra care needs to be taken during warm weather. If dogs are too hot and can’t sufficiently reduce their body temperature by panting, they may develop heatstroke which can be fatal. 

Heatstroke can affect any type of dog, but certain breeds and types of dogs are at increased risk, including brachycephalic or flat-faced breeds such as English Bulldogs, Pugs and French Bulldogs, as well as older dogs, overweight dogs and those with pre-existing medical conditions.

Symptoms of heatstroke in dogs include panting heavily, drooling excessively, appearing lethargic, drowsy or uncoordinated, vomiting and / or diarrhoea and collapsing.  


Dogs Trust has additionally issued the following advice to support dog owners during this period of hot weather:

  • Avoid walking or doing activities either indoors or outdoors with your dog at the hottest times of the day, so early morning or later in the evening is often best.
  • Always take plenty of water with you when out with your dog and make sure they have access to fresh water at home at all times.   
  • Tarmac can get very hot in the sun – check it with your hand before letting your dog walk on it so they don’t burn their paws. If you cannot avoid taking your dog out in the car on a hot day, even if travelling a short distance, avoid travelling during the hottest times of the day.   
  • Never leave your dog in a vehicle on a warm day. Not even with the window open. (Leaving your pet alone in a vehicle or tied up outside can also put them at greater risk of being stolen.)    
  • Use a cooling mat or wrap an ice pack or frozen water bottle in a tea towel for your pet to lie on if they wish.    
  • Use cold treats from the fridge for added moisture or make an ice lolly from pet-friendly ingredients.   
  • Don’t let your pet get sunburnt - use pet-safe sun cream.    
  • Know the early signs of heatstroke which include panting, difficulty breathing, tiredness, less keen to play, drooling and vomiting, and take immediate action.
