My senior dog has a soft, reddish lump on her belly. What is it?

Pet's info: Dog | Labrador Retriever | Female | spayed | 12 years and 4 months old | 80 lbs

Maggie developed this round soft knot on her belly. Size is the size of a peach. It is kind of reddish in color? Her appetite is normal. It doesn't seem to be painful when I rub it. Any thoughts?

This lump on Maggie could be a cyst, an abscess, a lipoma, a benign tumor, or a malignant tumor. Unfortunately in a senior lab, a malignant tumor is always a possibility. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Maggie seen by a vet on Monday to have the lump examined and diagnosed so it can be treated if needed.
