It took a lot of work to get Shanoa to learn to settle. As a puppy and adolescent she had no idea how to settle outside of her crate. If we weren't active she was pacing around. We reinforced quiet, settled behavior whenever she displayed it, and also actively worked on it using Dr. Overall's Relaxation Protocol. Now, at 2 1/2, she's great! She's absolutely ready to go whenever I am, but is content to hang out in the house quietly when I'm relaxing. I think it's partly age, but more the work that I've put into teaching her to relax.
