My old dog has a painless red lump on her lip. Is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 16 years and 9 months old | 13 lbs

I have a small, 16 year old, pomeranian and jack russell mix. She is about 12 lbs. Recently, she developed a red mass on the edge of her upper inside lip. She doesn't seem to be hurting by it and she eats and plays fine still. Her food and water dishes are ceramic and metal. I have 2 large male cats and a small toy fox terrier who all drink from the same water dishes as my Pim mix and they seem fine and nothing wrong.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Panda evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!
