We have recently switched about 2 months ago to feeding A mix of Diamond and Pro Balance. I have noticed that my dogs on this food have had a better coat and a better body type it has also been more easy for puppies to transition to other foods. We strongly encourage and recommend all Puppy Buyer‘s purchase a 5 lb bag of the mix from us for $15 we will bag it for you ourselves.  A slow transition is always better for a puppy and there diet. When a puppy goes home not only are they adjusting to you but they are also adjusting to being away from their siblings a new environment and new smells. We have noticed that a slow transition does better for them.
