Now, this is a dog that has some serious skills but unfortunately, won't be recognized by the Guinness Book Of World Records.
Finleyis a six-year-old Golden Retriever and he is capable of fitting six whole tennis balls in his mouth at once. The current Guinness World Record, set by a Texas golden retriever namedAugiein 2003, is for only five. However, the paperwork required to apply to Guinness is just way too time-consuming for the family to tackle right now.
So instead, they have documented his feat on his own Instagram page.
