Thank you for providing a picture of Dalton's bump! This bump could be a benign or malignant tumor, but I am very concerned that he isn't eating well and is losing weight. It is best that he is seen by a vet as soon as possible for not eating well and losing weight. This could be caused by dental disease, systemic illness, infection, inflammation, or injury. It would be good to have a physical exam, blood tests, and urinalysis done on Dalton to diagnose why he isn't eating and losing weight. The vet can also do a fine needle aspirate on his bump. To do this, the vet sticks a small needle into the bump 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. Once all of his symptoms are diagnosed, the vet can discuss treatment options with you.
