Rayal canin makes best dog food., we have German sepherd and he was just 1 month old when he came to our place and since then we are giving him royal canin , Our dog has very shiny long hair even after we shaved him in summers and within few months his hair grows fully . Quality of the product is super fine, gives proper growth and now he turns 15 months, he looks giant and very big. Packaging is attractive and my dog loves the smell of his food, you can him do anything for just one biscuit?
