No. Probiotics are living, which means they have a lifespan. Since probiotics are in a dormant dehydrated state, once you open a probiotic and expose it to even the humidity in the air, it only lives about two weeks.

By storing probiotics in a tub, there’s a very real possibility that some if not all those dormant micro-organisms come to life when you open it. Meaning, by the time you’re even halfway through the container, you’re likely feeding dead probiotics that are useless to your dog’s gut.

That's why these delicate microorganisms need to be in individually packaged capsules in blister packs to preserve them until they’re ready to be used. So, skip the big, ineffective tubs and opt for capsules and blister packs.
