A veterinarian has clarified that dogs licking their lips is not a sign of hunger or self-cleaning, and has emphasized that this behavior is "not normal" and may indicate underlying medical issues.
Understanding Canine Behavior
Many pet owners assume their dog licks its lips when hungry or before eating, but experts say this is a misconception. According to Dr. Megan Petroff, a residency-trained behavior veterinarian, persistent lip licking can be a sign of stress or a health condition. Dogs use body language to communicate, and monitoring such behaviors can provide valuable insights into their well-being.
What Does Lip Licking Mean?
Dr. Megan explains: "Lip licking can indicate stress. It can also indicate an upset stomach. If you notice your dog licking their lips, maybe hard swallowing, especially around mealtimes, they could have acid reflux. This is something you should discuss with your veterinarian."
According to Pet MD, lip licking may be a symptom of various conditions, including gastroenteritis, seizures, pancreatitis, kidney failure, liver disease, allergies, or age-related decline.
When to Be Concerned
Pet MD advises that if a dog suddenly starts licking its lips out of nowhere, owners should take immediate action as it could signal a health issue. For example, if a dog was chewing a bone and then begins pawing at its mouth and licking its lips, it might have something stuck in its teeth or throat. Owners should also watch for accompanying signs such as lethargy, loss of appetite, excessive salivation, or vomiting, and note the frequency and duration of the behavior.
Understanding these signals can help pet owners better care for their furry companions and address potential health problems early.
