The places I have stayed at in ND, SD, and northern Wisconsin all allow dogs inside the residence. That has included a mix of Airbnb and "cabins". It's kind of a must for us. The dogs get a good cleaning and look over, any needs get tended to, then they get to stretch out and rest on comfortable dog beds with their people.
I know I enjoy to stretch out and a good comfortable nights sleep after a hard day hunting.....I feel my lab has earned that too.
Sure, it may limit lodging options in some areas and it may add a pet fee, but in the overall scheme of things with what I have invested in my dog, equipment, etc.....it's not that big of deal.
