I have a two-year-old mix, more basenji then the pit she is mixed with. Daisy would not eat, she trained me as she was more stubborn then I was and I spent a fortune on food only to give it away. I finally went to the store, purchased chicken on sale, frozen mixed vegi's {canned has too much sodium} and brown rice. Cooked and mixed this up and she loves it. Brown rice has some nutrients in it where white is just a filler and is not good for people so I don't feed it to Daisy. I think if your only feeding your B rice with nothing else, it can't be very healthy for them. There are not enough vitamins or nutrients in rice and its just a filler. Daisy loves the mix and I finally found FreshPet or PetFresh (can't remember which one) she also loves so I alternate between them.
