Oral-care-specific probiotics, K12 and M18 strains, containing beneficial bacteria. Focusing on increasing good bacteria in the mouth instead of sterilization, it can be used with peace of mind on pets, who are members of the family. Flavorless with a natural sweetness, it's not affected by preferences and can be used not only for brushing teeth but also mixed into food or water. Using it at the end of oral care helps maintain a "odor-free, less-prone-to-staining" clean oral environment. Perfect for dogs and cats who dislike brushing. Reliable human grade. Made in Japan. *Please check the third image for the expiration date. *We have set the price to be affordable, so we cannot offer discounts. Thank you for your understanding. 12-21-10
