Why does my dog have a runny nose?

A dog’s nose is like his superpower. The part of a dog’s brain that analyzes smells is about 40 times bigger than humans!  A runny nose in dogs can signal serious problems. Sometimes, a runny nose is a symptom of an easy-to-treat issue such as seasonal allergies. Other times, it’s a sign of a condition that needs veterinarian attention. A runny nose in puppies can be because of a serious condition called distemper. While puppies and younger dogs are able to overcome it, it’s important to ensure that when you get a new puppy they’ve had their full set of vaccines—which will include the puppy distemper vaccine.
