Vitamin-fortified milk powder for puppies. Lactol has been saving the lives of puppies for generations. Made from easily digestible whey proteins, it is extremely palatable and of optimum biological value due to its excellent amino acid content, and the special low-temperature drying process, which preserves fragile protein structures. Because of this, more of the protein in the product can be utilized by growing animals. With added vitamins and minerals, Lactol provides a complete milk replacer feed.
