can jack russells ice skate?

i have a 12 year old jr who has been ice skating since he was a pup. we had jack russell ice skates as well as roller blades custome made for him. im not talking about him sitting there on the ice looking like a silly exploited pet, im talking if tanya harding could see my j.r im afraid she might take a tiny little crow bar to his lil paws.

his trainer thinks he's good enough for the a.k.a. olympics. is there such a thing and is it strange my dog can ice skate, is it safe? how old is to old for a jack russell to ice skate?? we're thinking about teaching him to ski next winter.
