This dachshund has a lipoma on its chest.

The word "lipo" stems from the greek word lipos, which means fat or fatty tissue. A lipoma is a fatty-cell tumor. 

These tumors are commonly found on older dogs, but young dogs and even puppies can develop them. They appear on the surface of dogs, and can be single or multiple. They are slow growing tumors that are usually benign. Malignant forms of the tumor are very rare.

Dr. Bock will remove this tumor by surgery.
