well not sure what your goal is with this post
but they do use dog sleds in the places where there practical to be used when hunting
the fact is simple ion why most don't
is there is a ton of costs and effort in maintaining a team of dogs., that is not worth the trouble for most hunters, or there costs!
which will also be the same reason your not seeing camels being used
as they too, are not native to where your suggesting them to be used in the USA , so now you have import fee's or buying from stock here, and still importing it to your area
folks don't wish to buy a animal just for packing out game, for one, or most dont
next is temperatures, I have NO clue what temps a camel work best it, but I doubt many places out west(usa) with elevation where most hunting happens and snow and cold temps, might be a flaw
SO WHY would anyone want to import a NON native animal into an area where pre existing animals already are and work fine?
I'm sure you can teach a monkey to play card games, but its most likely a lot easier to play with humans!
