This P2 topic covers the **status** of the 2018-2022 FDA DCM investigation: when it opened, how many reports were received, and the official end of public updates.\n\n## Status claims (verified C1 substrings of source_file)\n\n- `December 23, 2022: FDA does not intend to release further public updates until there is meaningful new scientific information to share.`   (FDA's official close of the investigation's public reporting — the last public update date on the page.)\n- `Between January 1, 2014 and April 30, 2019, the FDA received 524 reports of DCM (515 canine reports, 9 feline reports).`   (FDA's published case-count window for the investigation.)\n- `Although the FDA first received a few sporadic reports of DCM as early as 2014, the vast majority of the reports were submitted after the agency notified the public about the potential DCM/diet issue in July 2018.`   (Timeline anchor: FDA began notifying the public in July 2018.)\n\n## Scope note\n\nThis topic records only the investigation's reported status and counts.
