Q. My dog has what seems to be a fluid filled 'lump' hanging down from the area of his ribcage. It is slightly bigger than a tennis ball.

A. This should be checked as soon as possible to rule out a tumor and to treat as appropriate, especially at this age. A small sample can be taken with a needle to assess the underlying nature of the mass and determine the most appropriate treatment
DR. LEIGH PUSATERI, DVM
A. It could be a cyst, abscess, benign tumor (lipoma, etc), or possibly a malignant tumor. Have your vet take a look at it to determine the exact cause. Your vet can do a fine needle aspirate and examine the contents under a microscope to diagnose. Depending on the cause, your vet may recommend removal.
