There is no picture attached to your post, so I can't say if his penis looks normal or not. There should be two bumps on the side of the shaft of the penis. They are called the bulbourethral glands, and they become enlarged when the dog is excited or aroused.

Hello! There is a large bulbous gland at the base of the penis, in front of the testicles that gets enlarged when the dog is excited. It often strikes people as odd looking, but is completely normal. If you can snap a picture of it the next time it happens (I know, weird!), send it back in and we can tell you if it looks like normal anatomy or not. I can't find a link to a website for a good reference picture, or I would send you one. I hope this is helpful!
