TORONTO — Patches O’Houlihan, Canada’s reigning horse of the year, was euthanized Thursday.

Patches O’Houlihan, ridden by Sofia Vives, held off My Boy Prince to win the Grade 2 Highlander by a neck at Woodbine Racetrack on Saturday. Patches O’Houlihan was pulled up after the race and left the track in a van for further examination.

Veterinarians determined the horse had suffered a soft tissue injury. In a statement issued by Woodbine, owner/breeder Frank Di Guilio said Patches O’Houlihan’s condition worsened.

“We consulted with veterinarians and surgeons on an ongoing basis and it was determined surgery was not a viable option for a sustained quality of life,” Di Guilio said. “We are going to dearly miss watching him run, as will his many fans.
