Royal Canin Satiety Support Small Dog S 1kg. I bought this after being instructed to diet by my veterinarian, but my dog won't eat it at all. Even when mixed with canned food, he spits it out. I still have some of the opened bag left. Expiration date: July 2031 I will be selling the unopened bag. Because of my dog's picky eating habits, I'd like to sell it to someone who uses this as their regular food. Thank you.
