Re: Pro-Plan Chic.&Rice DOG for a puppy?
I generally switch puppies over to dog food at 4-6 months of age. I want to provide proper nutrition for them, while not over-loading their system and causing them to grow too quickly. We didn't switch one of ours as a puppy, continuing to feed him a puppy food, and he developed Pano. Glucosamine and Chondroitin cleared it up, but it was worrisome to see him limping.
Also, remember to keep them lean, even as puppies, so that you don't stress their developing bodies.
