"This Royal Canin formula is designed exclusively for pure breed Labrador Retriever puppies from 8 weeks to 15 months. If a Labrador Retriever Puppy grows too quickly, his weight can outpace his skeletal development, even leading to deformities. And, Labrador Retrievers (even puppies) are prone to gain extra weight, which can cause problems as they grow. This is why it’s important to feed a diet that is tailor-made for their specific needs."
