There's a secret to success in dog training. The secret is that there is no secret! All progress comes in proportion with the amount of effective effort given to work toward that newly learned skill. Whether it be teaching obedience to an excitable puppy, or setting boundaries to help an aggressive dog adapt to a healthier lifestyle. Both situations require the dog to learn and adapt to what it's been taught. Both will come with their unique sets of challenges. And both are subject to the concept of repetition and habit-forming. The more you do it, the better you get, the less you have to make a conscious effort as it becomes ingrained as a habit. Long story short. You want the results, do the work!
