Performance notes
With 6 probiotic strains combined with digestive enzymes and fiber, this formula takes a broader multi strain approach compared to single strain probiotics, which may offer more diverse gut support for dogs dealing with both loose stools and occasional constipation.
What buyers say
With 1,071 reviews averaging 4.2 stars and about 900 bought in the past month, this is an established product with a solid, if not top tier, reputation in the dog digestive remedies category.
How many probiotic strains does this product contain?
It's formulated with 6 different probiotic strains combined with digestive enzymes and fiber.
Does this help with both diarrhea and constipation?
The label positions it as both a stool softener and diarrhea relief aid, so it's meant to support firmer, more consistent stools in either direction. This is not veterinary advice, so talk to a vet for a diagnosed condition.
What size dog is this made for?
It's labeled for large breed dogs, so smaller dogs may need a different dosing approach. Check with your vet if you're unsure.
