Other than the Inuit sled dogs and Carolina dogs, are there any pre-Columbian domestic dog lineages left in the Americas? Additionally, is there much in a way of dog landrace formation in current Native American reservations?

Looking at wikipedia, there's been a number of extint breeds due to European contact, in North American neck of the woods...kind of curious as to whether there's much information available on existing dog populations.
