Animal Aiders provide veterinary-led, dog first aid courses all over the UK. Sophie Flux, who runs the company, gives some essential information on heat stroke. This happens when a dog's temperature increases beyond 40.5 degrees Celsius. At this temperature, a dog is unable to reduce its temperature itself. Heat stroke can result in serious health problems for dogs and even death.

Sophie tells us how to detect and treat heat stroke and offers suggestions for avoiding it in the first place. Even if you appear to have dealt with a problem yourself, Sophie recommends taking your dog to be checked by a vet to be on the safe side.

As a final caution, for anyone tempted to leave their dog in a car, Sophie has some surprisingly frightening statistics.
