Lumps and Bumps

Dogs can develop all kinds of lumps and bumps on or beneath the skin. Some are harmless while others require veterinary intervention. Look (and feel) for lumps and bumps every time you groom your pug. Lumpy skin problems include abscesses and hematomas, various types of adenomas, warts, and cysts.

Abscesses and Hematomas

A soft, painful lump may be an abscess or hematoma. An abscess is an infection that occurs at the site of a bite or puncture wound. A hematoma is a blood clot beneath the skin. Ear hematomas are common in dogs, especially those that have ear mites or infections that cause excessive scratching at the ear. Abscesses are drained by the veterinarian and the infection treated with antibiotics. Some hematomas disappear on their own, but others must be drained by the veterinarian.


Your dog may develop small, smooth, pink warts on the eyelids or legs. These benign (harmless) tumors are sebaceous adenomas and are commonly seen in older dogs. If tumors on the eyelids are large, they should be removed to prevent damage to the cornea.

Ceruminous gland adenomas are dome-shaped, pinkish-white tumors of the wax-producing gland that develop in the ear canal. Sometimes they become ulcerated or infected. Small tumors of this type are usually harmless, but large ones can become invasive and must be treated with surgery and radiation therapy.

Warts and Cysts

More commonly known as warts, papillomas are caused by a virus and can grow on the skin or inside the mouth. They're usually harmless and don't need to be removed unless they're causing a problem because of their location on the body. Warts in the mouth often go away on their own, but they can be removed by your veterinarian either surgically (cutting) or cryogenically (freezing).

Cysts are firm lumps beneath the skin. They form when hair follicles become blocked with hair and a cheesy material called sebum. Cysts are generally harmless, but they can become infected and may need to be surgically drained or removed.
