I haven’t read much about Inuit warfare, but there was nothing stopping them from using their dogs, bred for hauling heavy loads over vast distances, for carry soldiers. Same with the llamas. No doubt the Inkas used llamas for warfare, and if they wanted to, they probably could have bred them to carry soldiers, just like how camels and dromedaries were. Also, North America had buffalo. I fail to see anything inherent in the North American buffalo which would prevent it from being bred to plow a field the same way that the Water Buffalo in Asia was bred. Most likely the agricultural practices and warfare was different in the Americas which never drove the people living there to breed their animals for the same trades as in Europe and Asia.
