Royal Canin Babydog Milk is fully digestible and gentle on your puppy’s stomach, due to the use of milk as the food’s sole protein source. Reduced lactose content in the powdered milk ensures optimal, regular digestion. Starch is generally not easily digested by puppies, as the ability to process starch develops slowly in dogs – so 1st age milk contains no starch. Royal Canin Babydog Milk is as close as you can get to natural dog’s milk. The micro-granule structure allows the powder to dissolve instantly – within 5 seconds – and prevent clumping in the milk. This complete replacement milk product for puppies is perfect for raising motherless puppies, or as a supplement for large litters (from their 1st week to 4th week). The included antioxidant complex (vitamins E and C, lutein, and taurine) and mannan oligosaccharides support puppies’ still-developing immune system.
