Rogue was still all happy and playful when DH got home to take her to the vet. The vet examined her, and was pressing on her stomach to see if he could feel anything. He said that had the rope caused a blockage he would have been able to feel it (swelling/hardness) or she would show signs of pain with his exam. She seemed fine. He decided not to take an x-ray, and said to give her a few days to try and pass it on her own. He wasn't too worried - said that he's seen dogs her size do stuff like this and not have any issues with blockages. He said to bring her back if anything changes, but the fact that she was eating/drinking and not getting sick was a very good sign. Also, Rogue is up to 120lbs.
