This P2 topic records the **grain-free diet focus** of the investigation: the July 2018 launch targeting \"grain-free\" pet foods rich in peas/lentils/potatoes, and the diet-composition findings from reported cases (not a causal singling-out of grain-free foods).\n\n## Grain-free investigation claims (verified C1 substrings of source_file)\n\n- `that it had begun investigating reports of canine dilated cardiomyopathy (DCM) in dogs eating certain pet foods, many labeled as \"grain-free,\" which contained a high proportion of peas, lentils, other legume seeds (pulses)`   (July 2018 launch — FDA investigated reports of DCM in dogs eating certain pet foods, many labeled grain-free, high in pulses.)\n- `More than 90 percent of products were \"grain-free\", and 93 percent of reported products had peas and/or lentils.`   (Diet-composition finding from reported cases — observational, not a causal attribution.)\n- `The FDA's Center for Veterinary Medicine (CVM) and the Veterinary Laboratory Investigation and Response Network (Vet-LIRN), a collaboration of government and veterinary diagnostic laboratories, continue to investigate this potential association.`   (FDA's investigating bodies for the diet-DCM association.)\n\n## Scope note\n\nThese are observational diet-composition statistics from reported cases. FDA's causal conclusion (\"do not supply sufficient data to establish a causal relationship\") is in `FDA_DCM_interim_conclusions_no_causal_link`.\n","sources":["FDA DCM Investigation — 3 official docs — FDA Investigation into Potential Link between Certain Diets and Canine Dilated Cardiomyopathy (retrieved 2026-07-29)"],"source":{"authority":"FDA DCM Investigation — 3 official docs","title":"FDA Investigation into Potential Link between Certain Diets and Canine Dilated Cardiomyopathy","url":"https://www.fda.gov/animal-veterinary/outbreaks-and-advisories/fda-investigation-potential-link-between-certain-diets-and-canine-dilated-cardiomyopathy","retrieved":"2026-07-29","ref":"","doc_type":"official PDF","source_document":"FDA DCM (dilated cardiomyopathy) investigation","verification_file":"pdf-raw/dcm/FDA_DCM_investigation_page.txt"},"source_document":"FDA DCM (dilated cardiomyopathy) investigation","source_file":"pdf-raw/dcm/FDA_DCM_investigation_page.txt","tokens_estimated":260,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
