A dog's way of sweating is through panting so many dogs will pant a lot if they are extremely excited or if they are very tired.

Dogs pant for two reasons. The first reason is if they are hot. Panting serves the same purpose as sweating in humans. Thus, a panting dog might just be too hot. The other possibility is that the dog is in pain.

Excessive panting in dogs is caused by nervousness in the animal. If the animal is stressed you will find excessive panting. Weather also effects a panting response. If a dog is in hot weather without shade or water the dog will pant to cool itself off. Water often solves this issue.
