Just wondering. I know Pomeranian originated as a sled dogs.
How many would it take to pull an average sled in a snow race?
Seriously, the combined weight of the dogs would have to be more than the loaded sled for them to even get it moving. If the snow was more than a couple inches deep they wouldn’t be able to run through it!
BTW Poms weren’t actually bred from sled dogs, they were developed from a Spitz type aboriginal dog from which sled dogs, chows, American eskimos and lots of other Spitz types originated from. They are closely related to sled dogs.
