What does it mean when a puppy pants?

Panting is how dogs and puppies cool themselves off. They do not sweat, as people do.

Some reasons a dog will pant excessively:

• The dog is in pain

• May have eaten something that's toxic

• Chronic illness such as heart failure, Cushing's syndrome, or respiratory disorders

• Some medications will cause a dog to pant heavily

If your puppy seems to be panting excessively, it's time to have a vet examine him or her.
