The primary objective was to evaluate associations with municipality-level disposition and throughput outcomes; a secondary exploratory objective examined dog-level adoption and euthanasia pathways. We analyzed 68,032 dogs from 22 municipalities in Gyeongsangbuk-do, Korea, during 2016\u20132025. The primary difference-in-differences comparison included four municipalities that converted around 2021 and nine contracted controls. Event-study, exact label-permutation, and comparison-pool analyses served as diagnostics. Estimates were imprecise, no exact permutation p-value was below 0.05, and adoption and euthanasia had different pre-conversion trends. Excluding five newly digitized controls changed the adoption estimate from +4.65 to \u22121.86 percentage points. Censor-aware analysis estimated 13.33 additional days without a recorded disposition during the first year, but uncertainty was wide and the day-365 unresolved difference was small. In the secondary 35,366-dog subframe, mixed\/Jindo-type outdoor dogs had a lower adoption hazard ratio (HR, 0.39; 95% CI, 0.35\u20130.45) and a higher euthanasia HR (1.61; 95% CI, 1.37\u20131.90). Direct operation was not supported as a uniform causal intervention; municipalities should evaluate welfare and management components and target support to dogs at elevated risk.<\/jats:p>","DOI":"10.3390\/ani16162505","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T07:57:26Z","timestamp":1786521446000},"page":"2505","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the Administrative Label: Municipal Shelter Conversion and Dog Outcomes in Korea, 2016\u20132025"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3882-5078","authenticated-orcid":false,"given":"Byeong-Cheol","family":"Song","sequence":"first","affiliation":[{"name":"Agriculture and Livestock Division, Yeongyang County Office, 37 Guncheong-gil, Yeongyang-eup, Yeongyang-gun 36537, Gyeongsangbuk-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"ref_1","unstructured":"Animal and Plant Quarantine Agency (2026, June 24). 2024 Companion Animal Protection and Welfare Survey Results, Available online: https:\/\/www.qia.go.kr."},{"key":"ref_2","unstructured":"Ministry of Agriculture, Food and Rural Affairs, and Animal and Plant Quarantine Agency (2026, June 24).
