This is a great project that has pieces of an old scanner at its heart. I love the fact that this project is very functional, keeps the dog amused and was built on a recycled parts budget. I think it just needs some kind of water sprayer in the front that squirts just before it launches to prevent the inevitable ball to the nose that dog will endure. Have a look at the rest of the build pictures including a schematic of the launching electronics.

Not that it isn’t a neat hack, but should you be the one playing with the dog, and not a machination?
