Almost 50% of the pet population is overweight. Even a little extra weight can lead to serious health problems. Extra weight can reduce play time, impact mobility and affect the general health of your dog. Factors contributing to weight gain include age, lack of exercise and overfeeding. Many commercial pet foods are loaded with salt and fat, which improve the taste but also have dramatic effects on your dog's weight and overall health. Along with frequent physical exercise, choosing the right food plays a very important role in helping dogs reach their proper weight. At Hill's, nutritionists and veterinarians have developed clinical nutrition especially formulated to reduce dogs' body fat by 22% in two months, while keeping him or her satisfied.
