In fact, your pup’s sense of smell is his most important sense, so help him keep his nose healthy. But don’t worry if that nose is wet or dry.

Most of the time, a dog’s nose is cool and moist because his tear ducts drain into his nose. But if your pup’s nose is dry, don’t worry, it’s doesn’t usually mean that he is sick. In fact, and animal’s appetite and behavior are much better indicators of overall health.

However, if your dog has a runny nose or a nasal discharge, consult your veterinarian, as it could be a sign or an allergy or illness.
