Hill's™ Prescription Diet™
r/d™ Canine Weight Loss-Low Calorie

Weight reduction for overweight dogs.

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 nutritin especially formulated to reduce dogs' body fat by 22% in two months, while keeping him or her satisfied.

Important Feeding Information

  • These amounts are a starting point only. Determine the amount to feed based on TARGET WEIGHT rather than the current weight. Your dog may need less or more food to safely lose weight. Adjust as needed. If you are unsure or if you are not feeding this product for weight loss, ask your veterinarian.
  • Mix increasing amounts of your dog's new food with decreasing amounts of the old food over a 7-day period.
  • Prescription Diet formulas are available in a wide variety of dry foods and treats for your dog's unique needs and canned foods with delicious flavors your dog will love. When using with canned food and treats, decrease the amount of dry food to avoid overfeeding. Supplementation with other foods or treats is unnecessary and may decrease the effectiveness of the food.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your dog's condition.
  • To prevent suffocation, keep this plastic bag out of the reach of pets and children.
