My Charlie and Henry are 4lb 12oz and 5lb 2oz and athe vet said not more than 1/4 c each 2x's per day or I will have a porkie yorkie, and keep the amount the same when switching from puppy to dog food at 10month (they are 6months) and if I am going to add anything special keep it at 1 tsp to just one of the feedings...I do that to both the feedings because they like it and it is usually cooked ground turkey with celery or carrots cooked in or peas...They love veggies...so I figure it is not anything fattening...
