You've decided your dog's gut deserves better than a generic probiotic chew. Now comes the harder question: with dozens of products making science-sounding claims, how do you tell which dog postbiotic supplement is actually built differently?

Question What to Look For Red Flag

Is there published data? Peer-reviewed study or RCT "Clinically proven" with no citation
Are milligram doses listed? Individual ingredient amounts on panel "Proprietary blend" hiding doses
What is the format? Powder sachet (no binders) Chew with multiple artificial additives
What quality standards apply? NASC + cGMP Neither listed
