Unlike humans, dogs have very few sweat glands in their skin, so they cannot rely on dermal perspiration to regulate their body temperature. This function is performed by panting , using the tongue as a radiator , hence it is more common to see them with it outside after exercising, or while resting on a hot summer day. But it is not the only reason: other common causes are anxiety, fear or excitement . If the panting is excessive, it may be a symptom of a disease worthy of attention: then it is advisable to consult the vet.
