Heat Stroke in Dogs: How to Protect Your Dog Outdoors
Prolonged heat above 95°F claims the lives of dogs year after year, and the most vulnerable are dogs left outside in the garden. A dog without shade can suffer from fatal heat stroke in just a few hours. This article shows you how to prevent tragedy.
Why Are Outdoor Dogs Particularly Vulnerable?
- No shelter: If the dog cannot retreat to a cool, shaded area, its body temperature rises rapidly.
- Heating kennel/shelter: A metal or closed wooden kennel can turn into an oven in the sun.
- Heating ground: Concrete, gravel, and asphalt can heat up to 140°F.
- Running out of water: Water left outside can warm up, dry out, or tip over.
1. Shade and Shelter: The Most Important
The dog should be able to retreat to a cool, shaded area all day long. A closed kennel is PROHIBITED in the sun; during the hottest hours (11 AM–5 PM), bring it into a cool room.
2. Continuous, Fresh Water in Multiple Locations
Place several large, heavy bowls of water in the shade, change them several times a day, and add ice cubes.
3. The Most Vulnerable Dogs
Brachycephalic breeds, elderly and overweight dogs, those with thick coats, puppies, and dogs with chronic illnesses.
Signs of Heat Stroke
Heavy panting, excessive drooling, bright red or pale gums, staggering gait, vomiting, body temperature above 104°F, in severe cases, collapse, seizures.
Immediate Actions (Life-Saving!)
- Move to the shade, a cool place.
- Cool the abdomen, groin, and legs with lukewarm (NOT icy!) water.
- Offer water if able, but do not force it.
- IMMEDIATELY contact a veterinarian, even if the dog seems better.
