You take your dog to the vet immediately! It may be that your dog is just over weight, or, it could be heart or possibly an infection, but you need to see a vet to get a proper diagnosis and I hope you do it soon.
Rush to the vet like ASAP
I'm sorry but that means that your dog is having health problems and needs to be taken to a vet.
No! Call the vet!
what are the sounds? be more specific, heavy panting, wheezing, coughing etc.
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.
Difficulty in breathing(like heavy panting coughing and etc), Pain and Weakness. If your dog shows these behavior. Call your Veterinarian immediately.
dogs often do this to expell held up energy. it is basically a form of play. And the heavy breathing is obviously from the running.
See if the dog is lactating, or is she restless?

If your dog still breathing heavy after giving birth last night to 10 puppies, it is time to call the veterinarian. She may have a stuck puppy that she cannot get out, or she may have retained one or more of the placentas. If she is panting heavily for more than 2 hours after giving birth, it is an emergency and you need to call the vet.
