The heat in summer can be exhausting for dogs too, and can even be fatal. As dogs can't sweat, physical exertion in the heat or being left in a hot car can cause fatal heatstroke much faster than in humans. However, it's very easy to make summer an enjoyable time of year for your dog and make the heat more bearable.Avoid hot streetsPaved streets heat up very quickly – something we tend to forget thanks to the luxury of shoes. By the time the air temperature reaches 25 °C in summer, asphalt can be as hot as 50 °C. This can result in your dog's paws becoming chapped or burnt.Provide plenty of water Just like humans, dogs also need to drink plenty of water in hot weather. We recommend filling up your dog's water bowl several times a day and not placing it directly in the sun to avoid bacteria from multiplying.Smaller portion sizesOn very hot days, your dog will find it difficult to digest large amounts of food. You will probably also find that your dog won't need to eat quite as much when it’s hot.Do not leave your dog in the carParking your car and leaving the window open a crack is not enough. Each summer, many dogs suffer great distress and die from car heatstroke. If you see an animal in distress in a car and the driver is nowhere to be found, you should call the police. Red flags include excessive panting, howling and whining, as well as lethargy or unconsciousness.Keep your dog coolWhen the temperatures rise, any opportunity to cool off is appreciated. A relaxing stroll by a lake or stream, a children's paddling pool in the garden or an old, wet t-shirt will all offer welcome refreshment.
