I get a lot of questions about panting in dogs. Is it normal, can it mean he's sick, why does he pant in the first place? Those kind of questions. When you think about it, it makes perfect sense that some dog owners would find panting odd and a source of concern. After all, the normal respiratory rate for an adult dog is somewhere between 20 and 40 breaths per minute and with panting that can quickly soar up to ten times those rates.
