When you get frustrated, and you will, put your dog away and think about what just happened. Think about the mistakes you made, not the mistakes your dog made. When I started to get really serious about dog training I made the mistake of thinking it was always the dog. I thought I just needed to find that perfect dog to train. My wife (Cindy) is one of the best dog trainers I know. Over the years of watching her train her dogs, not just for dog sports, but to enjoy live with  I realized that every dog can reach some form of perfection. It just takes time and the love of being with your dog

That sounds like some really great advice! Thanks for sharing.
