Our dog has a two growths near his groin. They’re red and came very rapidly. They also begin to smell really bad this evening. He licks them and has a slight limp but he still lets us touch them. We would like to know what it is.

Oh, those do look bad! This could be malignant lumps. Unfortunately in a dog Toby's age, there's always a chance any lump could be malignant. They could also be cysts or from a skin infection. 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 in the morning to make him an appointment. Best of luck.
