Note: This calculator is intended only as a tool to assist you in determining how much food your Pet should consume. These are recommended quantities only, based upon general factors. Each pet is unique and therefore other factors should be taken into consideration such as your pet's intake of treats or other foods, environmental temperature and animal behavior. Breed may also be a factor in determining the amount of food your pet requires. We suggest you start with these amounts and then adjust to maintain ideal body weight. Consult your veterinarian about the proper care and feeding of your animals.
