"I started Smithers on Timberwolf Dakota Bison last year. He was getting slower in agility because I was having a hard time getting his weight down, even feeding low calorie dog food. After reading about how dogs metabolize energy, I suspected that the high carbohydrates in the "diet" dog food might be part of the problem. Now, six months later, Smithers is fit and full of energy. And his coat is awesome! All my pugs love Timberwolf and they all look and feel better than ever. Thank you for making such a great product!"
