I have a 2 year old springer spaniel mix (we think we lab). She is 70 pounds and full of energy. We are currently feeding her PurinaOne Lamb and rice formula, which is what she was on when we got her. I recently read up on the horrible ingredients in some dog foods. And I want to switch her to a premium dry dog food that is ideal for her size (70 pounds) and her energy level (high). Also, if you recommend a certain food, please let me know if I should supplement it with anything. There are so many foods and I feel overwhelmed trying to choose one. I hope you can help!
