No word yet on whether they have red noses, but some of Santa's horses have come down with a fever.
And that's enough to cancel a Christmas holiday event in New Castle County.
Officials said Monday that they had no choice to cancel the annual "Santa and His Pony'' event that had been planned for Saturday at Carousel Park and Equestrian Center after veterinarians diagnosed some of the horses with coronavirus.
Officials say the species-specific illness is not life-threatening to the horses, but that there is a risk that it could spread.
Officials say riding lessons, trail rides and cross-country course riding at the park also are canceled until further notice.
