imo measuring a dogs heart rate is an excellent way to figure if a dog has "wind" or not. get that heart rate up there, then see how long it takes a dog to fatigue.

Now that is a real and verifiable method of testing a dogs endurance and stamina. The reason the dog uses panting as a way of regulating his temperature is that the dogs highest concentration of surface blood vessels are in the tongue, mouth and nose area. The faster he exchanges outside air over that area, the less that air is warmed by his body, and the more efficient it cools the blood in those areas. Deep breaths mean the air stays in the body longer and is warmer as it passes over the mouth, short panting breaths keep the supply of air in the mouth area fresher, and therefore cooler. That is not opinion, or guesswork, it is biological science.
