Though snoring dogs can be somewhat annoying, just as snoring partners are, it's typically not a serious concern. A dog can have a minor obstruction, something like a loose area of tissue in the throat for instance, that is vibrating while he breathes in his sleep, thus causing the snoring. In addition, there are some breeds, like the Pekingese, who are simply more prone to snoring problems.

However, just like in humans, snoring can interrupt sleep patterns. If your dog is snoring loudly and consistently throughout the night or if he appears grouchy or tired during the day, his snoring may be creating a problem. This can often result from allergies or obesity. If allergies are to blame, try to pinpoint the allergen and limit your dog's exposure. If obesity is to blame, get him to lose a few pounds and see if that helps. If, however, the problem persists or otherwise seems severe, you may want to consult with your veterinarian.
