    I have been trying to lose weight because my owner and tyhe vet says I have to. I have tried other perscription diet foods that I did not like and they did not work. I like the taste of this and so far it seems to be working. I would recommend this to all my overweight freiends. Beau

  • Good product

    By on

    I have only given this to my dog for a week now, so I can not rate the results of the "diet" but I can tell you she LOVES this food. I was honestly shocked at how much she liked it. As a shelter rescue, she normally preferred human food to dry.

    My Shepherd had a weight problem which was caused by a chemical imbalance. Since changing her food to Royal Canin Veternerian Diet Weight Control she has lost weight and is healthy and can keep up with her younger sister.

    My lab is naturally a BIG girl. To protect her joints I wanted to slim her down a bit, but in a healthy, controlled way. This food is terrific.

  • Great for older Great Danes. We have one at Eight years old and one at Seven.

    This is a veterinarian prescribed dog food. I provided my veterinarian information and contacted them directly and filled the order. It was very easy. Up until now, we had to always go to the Vet's to buy the dog food. With it is delivered and each bag is less expensive than at the Vet's. I'm very happy with the products and the service. Thank you.
