Heatstroke can be fatal, often occurring if a dog is kept shut up in a house or car without shade, ventilation or water. But it can also happen as a result of over excitement or stress.

Avoiding heatstroke
Factors that can increase a dog’s risk of developing heatstroke include:

• Lack of water.
• Enclosed space.
• Excessive humidity.
• Obesity.
• Intense exercise.
• Old age.
• Cardiovascular disease.
• Lack of acclimatisation.
• Short-faced breeds, such as Boxers, Pugs and Pekingese, and dogs with heavy coats, are at particular risk.

All it really takes to avoid this serious problem is diligence and common sense. Never leave your dog unattended in a vehicle, or tied out in direct sunlight. Think twice about visiting busy, outdoor events on hot summer days

Signs of heatstroke

• Severe panting.
• Severe salivating.
• Vomiting.
• Diarrhoea.
• Raised temperature (40.5º C or above)
• Ultimately, collapse and coma.

Treating heatstroke

• Seek veterinary attention as soon as possible, as heatstroke can be fatal.
• Remove your dog from the heat into cool or shady area.
  Spray or sponge the dog's body with cool water, being sure the water contacts the skin and doesn’t simply run off the coat. Thoroughly wet the belly and inside the legs, and run the water over your dog’s tongue and mouth.
• Using a fan is another good way to reduce the temperature.
  Do not plunge your dog into cold water, as this may induce shock.
• Gently massaging the legs and body until you reach the vet, or the animal's temperature returns to normal (39.4º C is a safe temperature). A larger dog will take longer too cool down than a smaller animal.
• Once the temperature returns to normal, stop the cooling process to ensure you don’t chill your dog as this can lead to hypothermia.
• Gently dry your dog with a towel. If your pet is conscious, give him or her small amounts of water.
  Provide artificial respiration if necessary.
