PetLab Co. Probiotic Chews

PetLab Co.'s Probiotic Chews, 4 g chews in pork flavor sold 30 to a tub, rely on three Bacillus strains, Bacillus coagulans, Bacillus clausii, and Bacillus subtilis, totaling 3 billion CFU per chew as a blend with no per-strain split. The exact wording around that guarantee, whether it holds through end of shelf life or only applies at manufacture, wasn't confirmed on the manufacturer page we reviewed, so that basis is unstated. Prebiotics are fructooligosaccharides and galactooligosaccharides, each listed at 100 mg, and the chew also includes a 75 mg "synergistic postbiotic blend of yeast" made up of Saccharomyces cerevisiae and Cyberlindnera jadinii. Storage instructions call for a cool, dry place out of direct sunlight, with the tub resealed after each use. The product carries a NASC seal. Label claims include "Clinically Studied Formula" and "America's no. 1 selling probiotic chew for dogs," both stated by the manufacturer rather than independently verified here.

The main gap is the CFU basis itself, since the label doesn't specify through-expiry versus at-manufacture, and there's no per-strain breakdown of the 3 billion total. Dosing runs across three weight brackets: 1 chew daily under 25 lbs, 2 chews for 25-75 lbs, and 3 chews over 75 lbs. It's sold on Amazon under ASIN B089XVJHFK. One thing worth flagging: PetLab Co. also sells a separate product called Allergy & Immune Probiotic Chews, an 8-strain blend with added colostrum and omega actives, which is a different SKU entirely and shouldn't be confused with this base probiotic chew.
