Is Chronic Rhinitis Contagious in Dogs?

Rhinitis means inflammation of the nose, which usually leads to a lot of discharge. In dogs, this can happen for a number of reasons. Some of those reasons, such as parvovirus or a bacterial infection, are contagious to other dogs.

Common Causes

According to Ned F. Kuehn, DVM, the most common causes of chronic canine rhinitis are fungal rhinitis (a fungal infection in the nose), a tumour in the nose or lymphoplasmacytic rhinitis, which is a chronic nasal disease. None of these are contagious to other dogs.

Uncommon Cause

One uncommon cause of chronic rhinitis in a dog is an infestation of nasal mites, which is contagious to other dogs.


Other bacterial infections, such as canine distemper, that a dog's suffering from can cause chronic canine rhinitis. These infections are contagious to other dogs.


Until you properly diagnose the cause of chronic rhinitis in a dog, isolate the dog from other dogs. Wash your hands before touching a healthy dog.


According to "Dog Owner's Home Veterinary Handbook;" Debra M. Eldredge, DVM, et al.; 2007, the prognosis for curing chronic canine rhinitis isn't good. But, if the cause of inflammation isn't contagious, the dog can be with other dogs.
