Not even Serena Williams could yell at this ballboy
Submitter rajmahal shares this fantastic photo of Spencer, a charming and wide-mouthed rescued golden retriever whose love of tennis seems to rival even Serena Williams'.
When Spencer's not busy performing his impressive tennis-ball tricks, he "likes to make people smile," rajmahal writes. "He's also a therapy dog for local hospitals." If there's one thing we like better than a rescue pet, it would definitely have to be a rescue pet who's giving back to society! We applaud Spencer (and we hope he doesn't sprain his jaw).
