Four Leaf Rover probiotics for dogs: every product, by the label

Two S. boulardii-containing SKUs: standalone 'Saccharomyces boulardii' powder (fridge-preferred storage) and 'Protect' (shelf-stable, multi-ingredient detox/gut blend with S. boulardii + Bacillus blend). Storage guidance differs between the two despite shared organism — plausibly different stabilization, flagged for a label-photo sanity check.
