When dogs are breathing heavy it can be a sign that something is wrong. Heavy panting can be caused by heatstroke and their tongue can turn dark red, purple, or blue if they are suffering from heatstroke. The dog should be moved to a cool place and given cool water and if their temperature is over 104 degrees, you should get them to a vet.
