When a dog pants, How does it maintains adequate gas exchange? If it just ventilates the dead space how is co2 cleared?

This is somewhat beyond my area of expertise, as I am NOT a pulmonary physiologist. However, when dogs pant I do not believe they ventilate the reserve space, but simply increase the RATE of exchange, thereby cooling down their body. They would need to take deeper breaths to ventilate the dead space and they do not do this, as far as I know.
