Feeding Guidelines

These are broad guidelines only, designed to assist with feeding your pet based on their weight, age and activity level. Always check the feeding charts on your pet's food packaging in conjunction with these feeding guidelines. Required amounts may differ between individual pets, and adjustments may be required to maintain optimal body weight.

Once or twice daily feeding is recommended for adult dogs, unless otherwise specified by your veterinarian. Puppies and kittens require feeding more regularly, with the total portion divided into three or four meals throughout the day. Ensure fresh water is available at all times.
