If your pup has a clear runny discharge coming from his nose, this is quite common as long as he doesn't have any other symptoms of being ill. However, most vets recommend you keep an eye on the discharge in case an underlying cause should decide to make itself known. While you should keep an eye on any type of discharge, if you see any that has blood in it, is purulent, gray, or viscous in nature, you should take your pup in to see his vet. Once you get the hang of cleaning your dog's nose, it should only take a few minutes to get the job done.
You might think your pup doesn't care too much about that mucus buildup on his nose. But, if you watch, you will see him constantly licking at the side of his nose with the buildup. He doesn't like any more than you do, it probably interferes with his breathing and is far from comfortable.
Go slow and let your pup get used to having his nose cleaned. Even if you have to do the job in stages, the more time you give to the task, the more your pup will learn to enjoy this kind of treatment. This is one of those jobs that is sure to help build an even stronger bond between the two of you.
Be gentle, the skin on your pup's nose is very thin and easily damaged. If you see any changes in the color or consistency of the mucus, be sure to take your dog in to the vet for a check up.
