Low-fat diets can be beneficial for dogs prone to weight gain or with health conditions such as obesity, pancreatitis and inflammatory bowel disease. The formulas, available as low fat dry dog food and low fat wet dog food, are lower in fat and calories for healthy weight management, and will often contain pre- and probiotics to help support your dog's digestive health. Choose a complete dog food when possible, and remember that walks, exercise, and play are also essential for keeping your canine friend healthy and trim.
