China Rose got in trouble at class

Last night I was working China Rose in Obedience class. Our President Mary Price was instructing. Everything was goin great. Rose was in good forum. Never missed a beat. This was kind of a members only class, but had a student and his dog working with us, as he was having a problem with his dog and smaller dogs. So we were all helping to fix the problem. Mary brought in her own two toy dogs. A poodle and a chihahua. Our dogs were all lined up and instructed to sit stay. Mary then walked her toys in and out through the line. Corrections were made with the problem dog, and he got the message. Job well done. After class, we were still in the ring and I was talking with our pres. She reached down to treat her dogs, and China Rose did something she has NEVER done to any dog OUTSIDE of her own pack at home. She bullied them to get their treat. She jumped in and doin the Puggy Scream, tryed to run them off their treats. I was horrified. I quickly made the proper correction on her. We were all dumb founded, as like I said, Rose has never done this before. I have had problems with her at home doing this. Pugs and food. We all know the answer. Food belongs to Pugs. HA! No one else can have it. So now we will be working at home and in class on her problem. Glad that no toys were hurt. And pres. was laughing and no mad. The whole thing was embarrasing. Shame! Shame! Shame! I know your name Rose!
