Finding Pet-Friendly Accomodations

If you're looking for a hotel/motel that will accommodate pets, try CheapTickets.com.  Select "Hotels", fill in the location and dates, then check "Let me choose amenities."  When you click on "Search", you'll have the option to select "Pets OK."  In my limited testing, the search results looked much more extensive than what I've seen on other sites devoted to pet-friendly lodging.
