My older Maltese has a growing skin bump. Is it a skin tag or serious?

Updated On September 23rd, 2025

My 8 year old female Maltese has a skin-colored bump on the back of her neck. It started very small a few years ago but it has slowly grown. She doesn't go out in the sun very much. My dog's older sister has small bumps like this in various places on her body and her owner says it's from old age. Is my dog's bump a skin tag or age bump or does it seem dangerous? Please see the picture.

Thank you for the image. This is likely a benign skin mass known as a sebaceous adenoma. They are common in older dogs and arise from sebaceous glands in the skin. You would need to have your dog physically examined by your veterinarian for confirmation. Removal is recommended if the lump grows larger or becomes ulcerated, but others may grow in the same spot or different areas. Keep it clean and dry and be careful not to irritate it during grooming/brushing or bathing.

    These look like they could be sebaceous adenomas. They are common in older dogs and are typically benign. They can be removed surgically if they grow too large or become ulcerated but this does not mean they will not regrow or grow in another spot. You would need to have Chloe physically examined by your veterinarian for confirmation. Until then, monitor for rapid change or growth, discharge bleeding or pain associated with the bumps. These are symptoms that should be addressed by your veterinarian.
