My dog Ben is a 90 lb. German Shepherd/Collie mix. I always give “Big Ben” 3 cups of dog food daily,1-1/2 in the morning and 1-1/2 in the evening according to package instructions and vet instructions for his weight. I used to give Ben “ Rachel Rays” Nutrish Dog food when we first brought him home from the rescue. Later, when introduced to Excell, we switched and continued to give him his 3 cups daily.He always seemed to like it, and I like the fact that it was more nutritious for him , and it was cheaper than what I was paying ! Months went by, and one time I ran out of dog food. Since I remembered while up at the grocery store, I thought I’d pick up a bag of the Nutrish again just because I was there and we needed some immediately. I gave Ben the same amount of dog food that I always do. (3 cups daily ) This time however, even after he ate the Nutrish dog food , he seemed unsatisfied. He acted all antsy and acted like I had not even fed him yet. He kept wanting more so I gave him more.This led me to believe that he feels more nourished and satisfied with the Excell dog food,and that his body is getting more of what it needs from the Excell. For Ben’s sake and for the sake of my pocketbook , I don’t want to run out of Excell again!!!
