Our 4 year old is about 25lbs over weight. This was due to almost a year of prednisone and an on going battle with poly mytosis. We are trying to get him onto raw and he is doing great right now with half kibble and half raw, morning night feeding. The vet said to put him on one cup of food in the morning and one cup at night. Right now we are doing chicken wings/thighs and will progress more later on. Is a cup of kibble and a wing an thigh about the same as two total cups. I didnt mention we were doing raw with the vet because I dont think she is for it. Previously he was getting around 4 cups of food so we need to back it down. Our kibble right now is eagle pack holistic chicken.
