Alan Silvey was running alongside his Australian shepherd, Mystic, during a canine agility trial in October when the heart attack hit.
When Silvey came to, his first words were: "Did I qualify?"
Agility trials are all about confronting obstacles.
Just ask Silvey, 54, of Clearwater, who returns to competition this weekend when he and Mystic take part in the National Agility Championship. The event is part of the AKC/Eukanuba National Championship dog show in Tampa.
"I was thrilled to walk off the course and not have to be carried off on a stretcher," Silvey said on Saturday after making a run with Mystic at an agility event at the Bonjon Shepherd Ranch in Tampa.
