I hope I didn't come across as being judgemental, if I did it wasn't my intent and I'm sorry. I'm glad that you are going to give Zoe another chance, though. I think that working with her in a class is going to make a big difference in her behavior. Also, some of her energy will certainly get less as she gets older. One of my dogs, Adele, was a very hyper puppy and we had some problems with her being desructive. Even after walks, and playing constantly with my other dog she would find time to dig holes and chew. But, I noticed a big change in her behavior about the time she turned 1 1/2, and this summer she will be 3, and is more like a "normal" dog, she just needed some extra exercise with all the energy! Anyway, I didn't mean to ramble- just wanted to wish you good luck with the classes!
