Gagging

There is a place at the back of your pet's throat called the pharynx that acts like a switching station. It is responsible for sending food to the stomach and air to the lungs. When confronted by something unexpected, such as a trickle of postnasal drip, the pharynx doesn't know where to send it. It responds by gagging.

For dogs and cats, an occasional gag is just business as usual, says J. M. Tibbs, D.V.M., a veterinarian in private practice in District Heights, Maryland. Older dogs are especially prone to it because they produce a lot of mucus and their pharynges get more sensitive over time. When your pet is gagging frequently, however, there may be an infection or another problem that is irritating the pharynx.

Dogs with kennel cough, for example, will often gag. "You will hear 'cough, cough, cough -- ack,'" says Patricia Shema, V.M.D., a veterinarian in private practice in Glenn Dale, Maryland. "The ack is the gag. It sounds awful, but it is the cough that you have to worry about," she adds.

Anything that produces a lot of mucus, from viral infections to allergies, will often cause dogs to gag, says Dr. Shema. So can a more serious problem, like a weak esophagus or cancer of the throat.

Some pets have anatomical peculiarities that make them more prone to gagging, says Dr. Tibbs. English bulldogs and pugs, for example, often have extra tissue at the back of their throats that can be very irritating to them. In addition, cats sometimes develop polyps in their ear canals. If a polyp dangles into the pharynx, it can cause gagging.

In general, cats don't gag as often as dogs. The one exception is when an upcoming hair ball hits the throat. Cats will gag once or twice, then throw it up. Tonsillitis can also cause problems. "Cats have six tonsils, so imagine how it would feel if they were infected," says Margie Scherk, D.V.M., a veterinarian in private practice in Vancouver, British Columbia.

Pets will gag when their collars are too tight, says Dr. Shema. It might not happen when your pet is lying around, but you are sure to notice it during walks when the leash pulls the collar tighter against his throat.
