Dogs love to eat. Anybody who owns a dog, has been around a dog, or even seen a dog for more than few seconds knows that. Need proof? Drop some tasty food on the ground when a dog is nearby. Do it. We dare you!
Your dog is no longer a puppy (even though they are probably every bit as cute and energetic as they were when you first got them). With that growth comes a lot of changes. They need a new bed to sleep in, new toys and other accessories. Most importantly however, is your dog needs to transition from puppy food to adult dog food.
