I have had my 2 senior Chihuahuas on The Honest Kitchen Grain Free Chicken formula for over 2 years and will NEVER feed them anything else! When I began feeding the THK I noticed a decrease in issues (luxating patella, collapsing trachea issues) and a significant improvement in their mobility, coat and energy levels. Plus they always gobble it up, unlike dry kibbie, which they never really enjoyed eating without a ton of "goodies" added to it. I recommend this food to all my friend and family. Thanks for creating a great product!
