My 9 year old German Shepherd has a small pea sized hard black lump. It doesn't seem to bother him and he is in good shape.... other than being overweight.

This lump on Sam could be benign or malignant. In an older dog, there is always a chance any lump could be malignant. 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. Give his vet a call tomorrow to make him an appointment. I hope this helps!

    Without seeing Jackie in person and doing tests on the lump, there is no way I can say if it's cancerous or benign. In an older dog, there is always a chance a lump could be cancerous. 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.

Give his vet a call today to make him an appointment. Best of luck.
