Would it be okay to put my dog in the sled when i go sledding?

It all depends on how old and big the dog is, and if he/she is used to such things. My going on 2 year old middle size mutt rides on the four wheeler with me. And my almost 1 year old jack russell rides with us, though she prefers to jump off after bout 5 mins of riding. But other then that your dog should be just fine!! Have fun!!
