OXNARD, Calif. (AP) — A 10-year-old skateboarding bulldog that became a celebrity and made it into the Guinness Book of World Records has died of heart problems.

The Ventura County Star reports that the dog’s owner, Ron Davis, says that Tillman experienced an irregular heartbeat over the summer and developed a heart muscle disease. The dog died Tuesday on the way to a pet hospital.
