Should my pug get dental cleaning? Is anesthesia safe for their nose?

If there is tartar on your pug's teeth, and a bad odor coming from the mouth, he should have a dental cleaning under anesthesia. Dental cleaning without anesthesia is necessary as a lot of the tartar and bacteria are under the gum line causing severe gingivitis and the bacteria to enter the blood stream. I have not met a dog yet that lets us remove tartar under the gum line voluntarily, ie without anesthesia.
During the procedure your dog will be intubated to keep water and debris from entering the windpipe and to enable us to deliver the anesthetic gas and oxygen directly to the lungs. So the nose problems do not influence the ability to breathe during gas anesthesia. Brachycephalic dogs such as pugs have a slightly higher anesthetic risk than other dogs, but overall the risk is very low nowadays. Once the teeth have been cleaned you should brush them regularly with a soft brush and enzymatic tooth paste to delay the formation of new tartar. It is not possible to remove existing tartar by way of brushing teeth which is why brushing teeth is useful only after the tartar is removed.
