Methods to prevent heatstroke in dogs:

1. Prepare plenty of water for your dog. Dogs need more water in summer, so owners must prepare enough clean water for their dogs to ensure that their dogs can drink at any time.

2. Do not let dogs exercise vigorously on hot days. When taking your dog out, if the surface temperature is too high, it is not suitable to walk the dog, and the dog's foot pads may easily be burned.

3. Try to keep your dog in a well-ventilated place to prevent heat stroke.

4. Never leave your dog in the car. Even if you leave the windows, air conditioning, and everything in your car open, your dog is still at risk of heat stroke.

1. If the dog appears listless, unsteady gait, foaming at the mouth, and paddling with its limbs when playing outside If you are exercising and other behaviors, it is likely to be heat stroke.
