Im thinking about swapping my new puppy onto raw both as its healthier (my other dogs are raw fed) and also coz I cant believe how much he poops on his Lilys Kitchen wet food!LOL

He currently has 4 meals a day (13wk old, 3Ib Chiweenie) and also some Lilys Kitchen kibble for training treats so how is best to swap him over??
I know to just stick to chicken at first then introduce new things every couple of weeks but should I just swap him straight over or just swap one meal a day over until he is on all raw??
