We welcomed two German shepherd sisters into our family almost one year ago. Since then, it has been a battle to find a food they they will eat consistently. Being shepherds, they also have very sensitive digestive systems, and easily upset tummies. I was in my pet supply store one day, and saw a sample size pack of the frozen raw, thought "What do I have to lose ?"
Oh my goodness, they absolutely devoured it! I went right out and bought a bag of each type of the frozen raw. No upset tummies, good stools, and exponentially higher energy levels! My only complaint is that the frozen food doesn't come in a package larger that 7 pounds for multiple dog households like mine. Give Nature's Variety frozen dog food a try, you'll be glad you did!
