Suddenly, the dog starts licking obsessively—at carpets, blankets, or even walls. It appears restless, swallows frantically, and seems almost unreachable. For many owners, this condition is alarming. Behind it may lie a phenomenon that veterinarians call “licking fits.” Never heard of it? PETBOOK explains what it’s all about.
What Are “Licking Fits”?
Have you ever heard of “licking fits”? When a dog suddenly licks blankets, carpets, wallpaper, and anything else in its path as if in a trance, veterinarians refer to it as “licking fits.” The term describes the uncontrolled licking just mentioned. However, it is not considered a standalone disease but can appear as a symptom of various illnesses or conditions.
Typical of these licking and swallowing fits is a sudden onset of intense licking that can hardly be interrupted. The dogs appear restless, almost panicked, and often swallow and smack loudly. An episode can last a few minutes or significantly longer.
In some cases, the behavior escalates to the point where the dog tucks its tail and is barely responsive. To most owners, licking fits seem very frightening—and indeed, they should be taken seriously and promptly checked by a veterinarian.
What Causes Licky Fits in Dogs?
The exact causes of these licking and swallowing fits are not yet fully understood. Experts most commonly suspect a connection with the gastrointestinal tract. Acidity, reflux, food intolerances, or mild inflammations can trigger the unusual behavior. Other theories suggest parallels to neurological disorders or compulsive behavior. Stress, boredom, or a lack of or constantly changing daily structure can also play a role.1
For owners, it is important to take licking fits seriously and observe them closely. If they occur more than once, a veterinarian should be consulted. A thorough examination—possibly including a blood test or ultrasound—can help rule out or confirm organic causes.2
Why Dogs Eat Grass–and When Owners Should Be Cautious

What Can Owners Do About It?
In an acute case, it’s best to let the dog outside to eat grass. As PETBOOK reported in the article “Recognizing and Properly Treating Heartburn in Dogs,” this can help the dog with heartburn. Those living in an apartment without nearby grass can use cat grass as an alternative.
Effective immediate measures also include boiled elm bark (available in well-stocked pet supply stores) or healing clay. Both bind stomach acid and soothe the irritated mucous membrane. However, in the long term, it is crucial to treat the cause of the licking fits.
If stomach problems are suspected, feeding several small meals throughout the day and switching to easily digestible food can help. The veterinarian can also prescribe appropriate medication if necessary. An elimination diet may also be advisable after consulting with a veterinarian. This involves keeping a record over a longer period of time of which food triggers the licking.
If the dog generally seems stressed and has difficulty relaxing, structured daily routines with sufficient exercise, set rest periods, and targeted activities can help.
Why Licky Fits Should Always Be Taken Seriously
Even if a licking and swallowing fit eventually passes, it is a signal from the body that should not be ignored. Those who pay attention and act early can spare their dog unpleasant episodes and also recognize and treat potential health problems in time.
Licking fits are not harmless behavior but a possible warning sign of physical or psychological issues. Those who recognize the signs early and have them checked by a veterinarian can help their dog effectively.
