Stampyfeet

Stampyfeet is a canine affliction that I only learned of because of my association with Newton.

stampyfeet, noun. A canine neuromuscular disorder in which, due to the return of a dog's owner to its presence, the dog's forepaws rapidly and alternately strike the ground or floor. Usually accompanied by a submissive grin, excited panting, or nearly uncontrolled running about. Also known as stampyfoot or stampyfeets.
