Rarely is Mr. K seen without his one, true love: a squeaky tennis ball. His preference would be to have one with him at all times. The tennis ball, however, doesn’t feel the same way. It is a case of unrequited love, when you think about it…I can’t imagine enjoying being slobbered on, chewed up, spit out and ripped apart all together. Still, Mr. K fights hard for what he loves and when his beloved tennis ball tries to roll away, he’s not shy about chasing after it until it succumbs. What’s the one thing your pup can’t live without?
