There is no evidence that grain free foods promote weight loss in dogs, and unless there is a medical reason to avoid grains I don't recommend feeding these diets. Reducing calorie intake is necessary for weight loss, although increasing exercise can help as well. You can either talk to your vet to help estimate Tasha's ideal body weight and calculate approximately how many calories she should be eating in a day to promote weight loss, or you can try reducing the total amount of food she is getting in a day by 25%. Remember treats and chews have calories too - think of every treat as a piece of candy and try to minimize them as much as possible or replace them with a healthier alternative like a frozen green bean.
