Boston Terrier's are little bundles of energy who will literally run themselves in circles to expend that energy so they don't explode like a little doggy grenade.
Their boundless energy also cause them to act in strange and unpredictable ways, as demonstrated by Riley the Boston Terrier who sometimes likes to pretend she's a shark.
Riley asked the other dogs on Instagram if they liked to pretend to be a shark too, to which they replied they'd rather pretend to be a waste disposal unit, a royal food taster or a squirrel but never a shark. I guess Riley swims to the beat of her own drum!
