  • Formulation effective date is not supplied; retrieval date is the observation date. A product-listing publication date does not establish when this formulation took effect.
  • Automated source extraction has not received independent veterinary or human editorial review; evidence score is unpublished.
  • Catalog presence does not establish recall-free status or clinical suitability.
  • No publication date was extracted from matching manufacturer product metadata; source publication date remains unknown.
  • Large-breed growth eligibility is unconfirmed; product naming is not used as adequacy evidence.
  • No variant-specific dated offers were normalized; prices and feeding costs remain unknown.
