Thank you for including pictures of DesaRay's lump! This lump could unfortunately be a malignant tumor, which can be common in senior dogs. It could also be a benign tumor. 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 it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have DesaRay seen by a vet tomorrow to have this lump examined and diagnosed so it can treated as needed.

    This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Tu-spot to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.
