same like the other person posted, mix and take little away as days go by of old for 7 days till there no more of old food, i'm in the process of doing it with eukanuba switching from diamond which she came with, diamond has food issues back in jan so not wanting her to have it, then i found out byproducts for dogs aint good so now i will keep her on eukanuba for a week then switch again and keep it at nutro nature choice which is natural food healthier |
