How we use these sources
We separate two kinds of information. General canine-health education — how probiotics, prebiotics and the gut microbiome support digestion, stool quality and immune function — is checked against the organizations and studies above. PawBiotix product facts are drawn only from official product information; where a detail isn't publicly available, we omit it rather than estimate.
