Summer is a great time to enjoy outdoor activities with your dog, but while you are embracing yourself in the sun, don’t forget your dog can get overheated easier and quicker than you, leading to heatstroke.
How hot is too hot for dogs?
We consider your dog is suffering from heat stroke when his/her body temperature reach over 41°C, that is because normal cellular enzyme activity and cell membrane stability start to alter at 42.8°C.
At high ambient temperature, the dog’s body will try to regulate its temperature by increasing his/her heart rate, driving blood towards the skin, helping it to lose heat (heat dissipation). When blood get pooled towards the skin and other internal organs, the body’s circulating volume drops. At the same time, the body starts to dehydrate from heat dissipation. Overall there is less blood supplying to the heart and the heart can no longer support the circulation. Dysfunction and damage occurs with cellular damage, platelet and coagulation cascade abnormalities, and multiple organ failure.
What causes heat strokes?
• Expose to hot/humid environment
• Strenuous exercise
• Poorly ventilated environment
What are the signs?
• Heavy panting
• Racing heart
• Excessive drooling
• Red or purple gums and tongues
• Vomiting
• Diarrhoea
• Seizures
• Collapse or staggering
What are the risk factors for heat strokes?
• Brachycephalic breeds - French Bulldogs, Bulldogs, Boxers, Cavalier King Charles Spaniels, Shih Tzus, Boston Terriers, and Pugs
• Labrador retrievers / Golden retrievers
• Body weight > 15kg
• Confinement
What to do if you suspect your dog is getting heat strokes?
1. Take you dog to a place with shade
2. Cool your dog down by wetting him/her or by placing a presoaked towel over him/her
3. Offer cool water, but don’t force it
4. Do not use very cold water/ice bath/ ice packs
5. Seek veterinary attention immediately, ensure you do so even if your dog is already cooled and looks okay
How to prevent your dog getting heat strokes?
• Plan ahead by checking the weather forecast
• Avoid peak times, if a midday walk is unavoidable, make it very short.
• Always have water available
• Cool your dog down immediately after walks or exercise
• Keep his/her coat short
If you are cooling down your dog with a nice rinse of cool water or bringing your dog for a swim, ensure you dry your dog gently but thoroughly to prevent the development of hotspot (pyotraumatic dermatitis). These areas usually are wet, moist and red, be sure to bring your dog to the vet if you see them.
