Pet's info: Dog | Mixed Breed | Male | neutered | 4 years old | 40 lbs
My dog Riley has a bump on his stomach and I’m worried it may be a tumor. I know many tumors in dogs are benign but I’m still concerned. If you press on it gently in moves around like a weird bubble kind of.

I see Riley is four years old, and cancer in a dog that young would be unlikely. There is always a chance it could be malignant, but it's more likely a benign tumor or a cyst. 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 would call his vet tomorrow to make him an appointment. Best of luck, I hope this helps!
