Purina Proplan has been wonderful for my dogs. I have a 2 year old doberman mix named Nova. She has been on Proplan since I brought her home at 12 weeks. Started her on Large breed puppy. now she is on large breed adult. She has the most beautiful coat I have ever seen on any dobie. My 7 year old cocker named tootsie used to be on Iams but when I started the puppy on Proplan i switched her over too. She is on the senior she has done great on it also. Same as everyone else I wish coupons were more available. But I also stock up when it goes on sale. Thanks for a great product. edie
