My dog has a hard, painless lump on her head. Should I worry?

Updated On September 23rd, 2025

Pet's info: Dog | Staffordshire Bull Terrier | Female | 74 lbs

Hi, My staffy has developed a small lump at the base of her split skull. It is hard, but doesn’t seem painful, or bothering her it all. She is 6 years old, and fit and healthy in every other way.

There can be several causes of a lump like this, including a seroma or hematoma from hitting her head on something, an abscess or infection, an enlarged lymph node or salivary gland (if the lump is lower toward the jaw), a tumor or cyst, among a few others. Since some of these issues need veterinary care to resolve, I would recommend that Fifi get checked out by a vet. After physical examination, the vet may recommend a needle aspirate and microscopic exam or x-rays to see what the cause of the lump could be.
