I just started feeding NutriSource grain free about 6 weeks ago to my 2 spoiled German Shepherds. I love the results I am getting. My lean guy is starting to flesh out and my boy from Czech lines is holding a good weight and not getting fat. I have noticed more energy, smaller waste, and less doggie breath. I switched brands after doing research on grain free foods. I am very pleased to be able to purchase this food in my area. And I thought the food I was feeding was premium, the price was but the ingredients were not. Again, kudos to you from two very happy GSD’s.
