In my pack we have a wide spectrum of dogs that I work with. Our Pack being a pampered dog of royalty like Pumpkin our Pekingese and Koa a prey driven hunting Dogo Argentino. The vast variety of dog breeds and what they were bred for is something I always consider first when solving certain behavioral boundaries.
This is really at your pace and what you have for availability. You can take weeks to practice the ciriculum that your pack had just learned before scheduling your next or you can move on to the next with in a few days. Its is strictly up to your comfort.
