I began feeding my dogs Legacy food Wed evening. The are tolerating it well thus far. I do notice an increase in stool volume, and the colour of the stool is much darker. The volume might adjust as they get used to the food. Usually it takes two weeks for my dogs to incorporate a new food staple. It is interesting that my red merle Aussie, Cino, is responding well. Without exception Cino has been sensitive to all dog food/treats with chicken. Increased frequency of urination and increased volume of urine are his reactions. But, so far, not to Legacy!!!
