Watch out for the symptoms of heatstroke and learn to prevent it.
Dogs will suffer heatstroke if exercised too strenuously on a hot day, especially if it's hot and humid. Too little water or shade and excessive stress can also lead to heatstroke.
Symptoms:
High fever, sometimes as high as 108 degrees.
Extreme panting or sudden stopping of panting.
Shock or loss of consciousness.
Emergency Treatment:
Immediately move the dog to a cooler place.
As soon as you can, immerse the dog in cool water, or, if that isn't possible, pack it in ice.
Take the dog immediately to the nearest veterinarian.
The veterinarian will continue to cool the dog and administer fluids intravenously. Treatment may also include antibiotics and steroids.
Precautions:
Run in the early morning or evening after the temperatures have dropped.
Carry water for you and your dog. Stop often to drink.
Stop and cool off if your pet appears to be straining and panting heavily.
A sure danger sign is if your dog stops panting during exercise. If he does, stop immediately and cool off your dog.
