Overview
Four Leaf Rover Yeast Support is a beef-flavored powder supplement for dogs, built around a blend of organic herbs including pau d'arco, goldenseal and oregano leaf plus MCT powder, sold as a 30 day supply sized for medium dogs.
Despite sitting in a category labeled Probiotics, the ingredient list is herb-based rather than a probiotic strain blend, so this is more accurately a yeast-support herbal formula aimed at skin, ear and paw health tied to gut lining. At 3.8 stars across 335 ratings, it sits toward the lower end of the range for this kind of supplement.
- 51 gram powder, 30 day medium dog supply
- Organic herb blend including pau d'arco and goldenseal
- Includes C8/C10 MCT powder
- Beef flavor, gluten-free
Who it's for
Fits owners managing a dog with recurring skin, ear or paw issues that may be tied to yeast overgrowth, and who want an herbal rather than pharmaceutical approach. Less suited to owners looking for a straightforward probiotic strain supplement, since this formula is herb-based.
Strengths and trade-offs
Drawn from this product's published specifications.
- Organic, gluten-free herb blend
- Beef flavor for easier mixing into food
- Sized as a 30 day supply for medium dogs
- 3.8 rating trails many other dog supplements
- Herb-based formula, not a probiotic-strain product despite the category listing
Performance notes
The formula combines a proprietary organic herb blend with C8/C10 MCT powder, delivered as a beef-flavored powder meant to be mixed into food. The 51 gram package is sized to last 30 days for a medium dog, so dosing is built around that timeframe rather than a longer course.
