I purchased a tiny Toy Fox Terrier. When I received the little guy, he definitely had GI problems and did terribly on regular commercial dog feed. Fortunately someone directed me to Fresh is Best® and we have ever looked back since. It took him roughly 8 months to get his GI problems resolved, but the improvement was slow and steady. Today he is a sturdy 7 pound racing fit Toy Fox Terrier who enjoys his life very much and is quite the “foodie”. Fortunately Fresh is Best® has several different foodss and treats to serve as his main diet. Thank you very much for your quality product and thank you for all the time you listened to me and helped me!!!! That is what has truly made the difference.
