A dog food calculator is intended as a tool to help you in determining how much food your pet should consume. These are recommended quantities only. Each dog is unique and therefore other factors should be taken into consideration such as your dog's intake of treats or other foods, environmental temperature and animal behavior. Dog breed may also be a factor in determining the amount of food your pet requires. Please consult a vet about the proper care and feeding of your dog.
