What should B2B buyers verify when sourcing probiotics and prebiotics for dogs or cats?

Identify probiotic microorganisms to the level required by the destination market, specify viable count at manufacture and at end of shelf life, and define storage and analytical methods. For prebiotics, record the exact material, specification, intended function and use level. Confirm compatibility with heat, moisture, flavours and the selected dosage form. Marketing should distinguish ingredient presence from demonstrated finished-product performance, while labels and online content should avoid disease-treatment implications unless lawfully authorised.
