Lactase, also known as "biological ferritin"; Milk protein; Lacfinex) is a traditional preparation of active antibiotics. Lactase is white or yellowish dry powder; Slightly smelly, tasteless, insoluble in water. Used for dyspepsia, abnormal intestinal fermentation, infantile diarrhea, and infantile defecation.

Lactase is a dry preparation of live enterococcus, which decomposes sugars in the intestine to produce lactic acid, which increases the acidity of the intestine, thus inhibiting the growth and reproduction of spoilage bacteria, preventing intestinal fermentation, reducing gas production, promoting digestion and stopping diarrhea.

If the puppy's digestion is normal, there is no need to feed the puppy lactase all the time. Moreover, it is not very good for people to take medicine and give it to small animals for a long time.

So I suggest you don't keep feeding lactase to your puppy. When you have indigestion, eat a little.
