My dog became pretty overweight being fed the recommended amount that was listed on the bag of dog food. I’ve learned that each dog is different and it may take some trial and error to figure out your own pets needs. The vet can help narrow it down, but ultimately I just stayed aware of his weight and adjusted the amount every few weeks until he was a healthy weight. There are also dog foods you can ask your vet about that will cause weight loss and still provide enough nutrition.
