Just because a label sends the message that a food is good for weight control doesn't always guarantee it's lower in calories than other foods.
You switch your overweight dog from her usual food to one whose label suggests the kibble will help her slim down, yet she doesnt lose an ounce. Maybe she even gains weight on this new food. How can that be? Its because calorie levels for weight management foods for dogs are all over the place, says board-certified veterinary nutritionist Deborah Linder, DVM, who heads the Tufts Obesity Clinic for Animals.
