Why does my dog have a black neck bump and scabby, crusty ears?

Question

My dog had a bump on his neck. It burst a couple of times and has since tripled in size and part of it is now black. It doesn’t seem to bother him but it is scary to look at. What is this and is it life threatening? What is the treatment for this? He also suddenly has very very scabby and crusty ends on his ears. Are they related?

This lump on Johnstamos (LOVE his name!) could be a cyst, a benign tumor, or a malignant tumor. Because it has tripled in size, that does make it concerning. 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. As for the scabby and crusty ears, those could be due to an ear infection or allergies. Give his vet a call to make him an appointment to have both these things checked out. I hope this helps!
