Your little Sophie sounds very alert and smart indeed!!! Yorkies tend to be somewhat stubborn but with persistent short periods of frequent training they can soak up everything we teach them if we keep them engaged and enjoying the training by making a fun game of it and always giving them positive reinforcement for getting it right. I find them delightfully easy to train in most things.
