Anything behavioral that has changed in your dog means that you need to take him to the vet. Your vet will rule out any medical issues before you continue any further. If he has a clean bill of health, but doesn't seem interested in the food like he used to be, it could be that he is bored of the food, or had a scary/traumatic experience where the food bowl is. Try moving the food bowl somewhere else and/or switching his food to either a completely new food, or a different flavor.
