They take longer to mature and need puppy food longer, up to age 18 to 24 months. Their joints and their hearts particularly need extra glucosamine, chondroitin and omega 3 fatty acids. If you have a large breed dog, you know their size and power doesn’t make them invulnerable. They need as much tender loving care as a toy breed, including wholesome food made with local, traceable ingredients.
