NEVER leave your dog in your car! Some signs of heat stroke include: panting excessively, have redness around his eyes, show muscle weakness, irritability, may start vomiting, may collapse.
After being hot, give your dog cool water, not cold water. Sponge him down with a cool wet towel or soak him in a tub of cool water and keep a fan on him.
If your dog’s gums are gray, his tongue is blue, or he becomes unconscious, take him to a veterinarian. Heatstroke is an emergency, and you may need to make a quick trip to the veterinarian or emergency clinic.
