My puppy has a black mole-like growth on her back foot. What is it?

My daughters 13 week old German Shepherd mix puppy has a growth near her back foot that looks like an oblong mole that is black in color. It is smooth. At first I thought it was just something caught in her fur. Any idea what this could be?

Without seeing it in person, I can't say for certain what it is, but it may just be a benign growth like a mole. 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 its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd call Athena's vet to make her an appointment. Best of luck.
