A balanced diet is important to a dog's growth, energy, and overall health. Every dog has unique nutritional requirements depending on its size, breed, and stage of life. Adult dogs require sufficient nutrients to meet energy needs and maintain and repair body tissues. Nutritional supplementation can benefit working dogs, such as herding, hunting, and field dogs, as a source of additional energy; as well as senior dogs, pregnant & lactating females, and puppies to support the immune system, fetal development, and growth. Canine Red Cell is a liquid vitamin-iron-mineral supplement that helps keep dogs performing on the hunt, the track, and in the show ring. Contains iron and zinc, which support the immune system. Ideal for dogs in all life stages, including gestation, lactation, growth & maintenance of adult dogs, puppies, and seniors. Palatable beef & liver-flavored liquid can be fed directly or mixed with regular food.
