Dog training is a form of performing that dogs just love to do for their owners. Participating in pet shows is another. Dog agility is another form of pet performance. Of course, there are a very few pets who appear on television or in movies, with the obvious best known pet performer in that category being Lassie, but there are many others, including more exotic pets/wilder animals such as dolphins - who could forget Flipper? - and kangaroos - the ever-popular Skippy.
