I don't know about finding discs, but Mr. Gus, Tom's adorable little guy, does a great job of getting a frisbee that is larger than him and returning it. What kind of pup is Mr. Gus, Tom? Terrier?
I love watching Mr.Gus and proves how truly wonderful dogs are when it comes to brightening our day.
I believe Gus said he is a "Yorkie" (Yorskhire Terrier).
