We had a squirrel in the drop ceiling of our basement. That little monster was running around crazily, tearing everything all up, making a huge mess! The guy from RNT came, with cages, and his dog, a Sheltie, named "Shelby". It was amazing to see that little dog work, following the scent, tracking to where it came in and went out, found where it was holed up, and eventually into the cage. The dog did all the work!!! 100% satisfied, would recommend to all-they get the job DONE!!!
