A dog's body typically has a narrow operating range for its internal temperature of between 100 Degrees F and 102.5 Degrees F. When a dog's body temperature rises above the upper limits of its average temperature range, several things happen. For example, the blood temperature rises. The brain then detects this rise in temperature and sends more blood towards the skin to help it cool. Respiration also increases in an attempt to draw cooler air into lungs and blood. You will recognize increased respiration as panting. Now consider what happens when a dog is placed in a hot, humid environment. The air being inhaled is hot and, therefore, diffusion of body heat through the skin and respiration is not very effective. With this, chances of a dog overheating increase. MiraCool Doggie Bandana effectively works from the outside in to deliver cooling sensations that pass from dog's pulse points, and other blood vessels close to the skin, to dog's entire body.
