We’ve got a 12 year old Shih tzus (spring that and active bless her) who loves Millie’s (and I love the oickuoable mess free pop) and now also a 14 week old Shih Tzu puppy who’s regularly ignoring her grain free puppy kibble to steal Seniors Millie’s kibble. Millie’s helpline say totally fine to feed both countryside mix or obedience mix but I wondered if anyone here has used Millie’s for non working or sporting breeds and also for seniors and juniors despite the food not being labelled as such for either?
