Why not just do a web search for motels in Morris or Benson? There can't be too many motels in either city. I did a quick web search and found the Best Northland Prairie Inn in Morris. They allow pets for $15/night. There has to be some mom & pop motels that would allow dogs. I think a little time searching the web and making a few calls will get you what you need. Or maybe someone on this site is from the Morris/Benson area. Good luck.
