Tillman, the thrill-seeking English bulldog with a penchant for skateboarding, has sadly passed away. Tilly's owner, Ron Davis, confirmed the passing on Instagram, adding that he's thankful for all the memories his "best bud" has given him over his decade in the spotlight:
Tilly reportedly started experiencing an irregular heartbeat earlier this year before being diagnosed with a heart muscle disease, according to BuzzFeed. Born in 2005, Tilly became a viral celebrity in 2007 after Ron shared footage of the skateboard-inclined dog displaying his gift on YouTube. Tilly's fame and undeniable skill also earned him an appearance in an Apple ad, a spot on the TV series Who Let the Dogs Out, and a Guinness World Record.
Rest in power, Tilly.
