Dogs lick their lips frequently for various reasons, ranging from normal behaviors to signs of underlying medical issues. It's important to observe the context in which your dog is lip-licking to determine the cause.
Here's a breakdown of potential reasons:
-
Anxiety and Stress: Lip licking can be a calming signal or displacement behavior in dogs experiencing stress or anxiety. This is often accompanied by other body language cues like yawning, panting, whale eye (showing the whites of their eyes), tucked tail, or flattened ears. A stressful situation might include a visit to the vet, loud noises (fireworks or thunderstorms), or interaction with an unfamiliar dog or person.
-
Nausea: If your dog is feeling nauseous, they might lick their lips frequently as a response to stomach discomfort. This can be caused by eating something they shouldn't have, motion sickness, or an underlying medical condition.
-
Dehydration: A dog who is dehydrated may lick their lips in an attempt to moisten their dry mouth. Ensure your dog always has access to fresh, clean water.
-
Allergies: Allergic reactions can cause irritation and itchiness around the mouth, leading to excessive lip licking. This might be related to food allergies or environmental allergens.
-
Oral Problems: Dental disease, a foreign object lodged in the mouth, or mouth sores can cause discomfort and excessive lip licking. Check your dog's mouth regularly for signs of problems.
-
Pain: Pain, especially in the abdominal region or mouth, can trigger lip licking as a coping mechanism.
-
Other Medical Issues: In some cases, excessive lip licking can be a sign of a more serious underlying medical condition, such as neurological problems.
When to be Concerned:
If your dog is licking their lips excessively and it's accompanied by other symptoms like vomiting, diarrhea, lethargy, changes in appetite, or signs of pain, consult with your veterinarian to rule out any underlying medical conditions. It's also important to note if the lip licking is a new or sudden behavior. Observing the circumstances surrounding the lip licking can provide helpful clues for your vet.
