Dogs mainly rely on panting in order to cool themselves, which allows them to
exchange warmer body temperatures with the cooler air outside.
Both panting and convection cool the body by
exchanging the warm body temperature for the cooler air outside.
Not exact matches
However, two known predators of sea lions — great white sharks and salmon sharks — have counter-current heat
exchanges in their
bodies that make them partially
warm - blooded and the tags would have reflected higher
temperatures.
Dogs resort to panting to
exchange warm air for cool air, but when outside air
temperatures are close to or exceed a dog's normal
body temperature, cooling by panting is not an efficient process.
The relative
temperature of the two
bodies only defines the magnitude and direction of the NET energy
exchange, which can only be from
warmer to cooler.
