Vets decide Lost in the Fog will have to be euthanized

Lost in the Fog, the national- champion sprinter from California whose winning streak was one of horse racing's happiest stories a year ago, has inoperable cancer and will have to be euthanized in the next couple of weeks, his trainer and veterinarian announced Friday.

A tumor was found on Lost in the Fog's spleen shortly after the 4-year- old colt was taken to the UC Davis large-animals clinic over the weekend with what had been thought to be a case of colic. Two more tumors were found Friday afternoon, one of them the size of a football, Dr. Don Smith said.

``We know the end is inevitable,'' trainer Greg Gilchrist said in a conference call with reporters. ``We certainly don't want him to go through more than he needs to.''

But because Lost in the Fog apparently is not in great pain, the horse will be brought back to his stall at Golden Gate Fields racetrack in Albany for his remaining days, Gilchrist said.
