They introduced a tunnel in Gracie's puppy class last night. She went right through it without any fear. She ran to the other side to see her daddy. She was wiggling her butt the whole time. It was the funniest thing. Some of the other pups were nervous about it. She also walked on the narrow piece of wood without any problem. Being a low rider helps! :) She has about 2 more puppy classes. I want to continue her obedience training and enroll her in agility classes. Any of you planning to do agility with your vertically, but fast, challenged, low-riding Corgis?
