The Question
“My dog paws at his lips often after eating or drinking, and other times. It’s as if it hurts or burns. He’s fairly gentle when he does this. The vet gave him a cortisone shot, but it showed zero noticeable help. His lips look bright pink. I clean his bowls and water often. What can I do?” – Terri
Quick Info
Dear Terri,
What you are describing often points to discomfort around the lips or oral cavity, much like when we have a mild burn or irritation and instinctively touch the area. In dogs, repeated pawing at the mouth after eating or drinking can be associated with oral inflammation such as gingivitis, early periodontal disease, or even something as simple as food trapping along the gumline. Bright pink lips suggest increased blood flow to the area, which is consistent with inflammation. Another possibility to consider is contact irritation or hypersensitivity, especially if bowls are plastic or certain foods trigger a localized reaction, although the lack of response to a cortisone injection makes a purely allergic cause less likely.
It would be very worthwhile to take a closer look inside the mouth under good lighting, ideally with your veterinarian, to assess the teeth, gums, and inner lip surfaces for subtle lesions, foreign material, or areas of pain. Some dogs also develop conditions like lip fold dermatitis or localized infections where moisture and bacteria accumulate, particularly after drinking. Switching to stainless steel or ceramic bowls, if not already using them, is a simple step that can reduce contact irritation. If the behavior persists, a dental evaluation, sometimes including sedation for a thorough oral exam and possibly dental imaging, becomes important, as early oral disease can be easy to miss but uncomfortable enough to trigger this repeated pawing behavior. I hope this helps!
