Did you know it is better to practice short training sessions and stop when your dog still wants more? This strategy will keep training interesting and you will avoid over training. I have always known this, but this was reinforced even more when I did sheep herding with my dogs three summers ago. I am always trying to add more skills to my training repetoire, and thought my two Collies and Shetland Sheepdog would enjoy the experience. My wife Cassy and I got up at 5am to avoid the traffic and drove 90 minutes to our weekly training sessions at the sheep herding farm.
