For medium breed puppies (adult weight from 11 to 25 kg) - Up to 12 months old. Immune system support : Growth is an essential stage in your dog's life: it is the time of big changes, discoveries and new encounters. During this key period, the puppy's immune system develops gradually. Medium Puppy helps support your puppy's natural defences thanks particularly to a complex of antioxidants including vitamin E. Digestive health : Combination of nutrients with high quality protein (L.I.P.*) and prebiotics (FOS) to support digestive health and balance of intestinal flora, which contributes to good stool quality. *Protein selected for its very high digestibility. Short growth - high energy content : Meets the high energy needs of medium breed puppies which have a short growth period.
