The best weight controlled dog food is a healthy diet of "human" food targeted at regulating the same organs and weight issues as a human.
Dog Food is very misunderstood. When we humans process food, we process what sells. What doesn't sell to humans gets sold to companies that process it into other usable product, i.e. dog food.
A healthy diet for a dog is quite different but can be accomodated with household items (if your a healthy eater as well).
Ask your vet about what is safe to feed a dog and what your particular dogs nutrition guide and diet would look like.
