Hi All, I am thinking of changing my dogs over to Royal Canin and would value anyones opinion on this brand. I have 6 large dogs, 2 are pups and currently I am not happy with the food I am feeding them. If you have any comments, good or bad I would greatly appreciate it. Also what are the puppy packs that you are given when you have a litter like? Thanks in advance. Leanne
