What to do after a dog has heatstroke:

1. After a dog has heatstroke, move it to a ventilated and cool place in time. You can use a fan to blow the dog.

2. Wet the dog with running cold water, making sure the water pressure is low. Do not completely submerge the dog under the water, because it will lose its temperature quickly, which may lead to other complications. Make sure the water is not too cold, as very cold water constricts blood vessels and prevents cooling.

3. Once the temperature drops below 39°, take him to the veterinarian. On the way to the vet, turn on your car's air conditioner and windows, or prepare a small fan to help cool your dog.
