I'm currently feeding my 12 week old puppy Royal canin, which she enjoys so happy to stick with it. Is anyone else out there using it and if so what type? I have bought the one for medium dogs as she was on medium hills science plan from the breeder. When I emailed Royal Canin they said she should be on the one for small dogs but Cockapoos aren't classed as a small breed are they? Now I'm left really confused, any advice will be much appreciated.
