Automatic Dog-Petting Machine Is Equal Parts Adorable And Functional

This puppy petting machine is perfect for any good boy … well almost any.

This first dog in this videos seems to be enjoying the elaborate back scratcher, getting so relaxed they even let out a yawn. But the smaller pup needed one more hand than this machine could provide. Perhaps the owners should have made a sign that reads, “you must be at least 22-inches to go on this ride.”

Rude Goldberg would be proud.
