Oh, so glad everything turned out okay and understand how scary this can be.
Same kind of story (before YorkieTalk knowledge)..... I used to let Piccolo chew on Dingo bones, which are rawhide. One day she started choking because she swallowed this huge piece. Thankfully, I was able to reach down her throat and pull it out. Scared me to death. Now I only let the pups have bully sticks and watch them as they chew.
One more reason for me to be thankful for YorkieTalk and the knowledge that I have gained about rawhides and bullysticks.
