A dog’s nose not only dominates her face, but her brain, as well. In fact, a dog relies on her sense of smell to interpret her world, in much the same way as people depend on their sight.
A dog’s wet nose is commonly a sign of good health. Dogs with dry noses, however, are not always in poor health. Dog’s noses change temperature throughout the day for numerous reasons, many of which are not due to illness. Symptoms in addition to a warm and dry nose, such as nasal discharge or cracked skin, may indicate that your dog needs a checkup with his veterinarian.
