Medical records of 3189 dog and 1390 cat visits presented between 1 January and 31 December 2021 to an advanced small-animal practice were retrospectively reviewed. Retrieved data included temporal characteristics of presentation, species, signalment, clinical diagnosis, diagnostics, and treatments. Visits were retrospectively categorized using a triage approach based on the five-point Manchester Triage System (MTS). More than half of all events were classified as non-emergency visits (blue and green triage); the proportion of red triage (immediate) cases was higher among feline than canine emergency presentations. The most frequent patient presentations to the after-hours emergency service occurred in spring and summer, with May and April being the busiest; holidays and Sundays had the highest average number of cases per day during the day shift. Causes of emergency visits were mainly due to gastrointestinal disorders in dogs (32.3%) as well as in cats (28.6%). Symptomatic therapy was the most common intervention in dogs (75.1%) and in cats (49.6%), followed by diagnostics (dogs 17.5%, cats 36.0%). These findings highlight the broad spectrum of after-hours emergency presentations in small-animal practice and the high proportion of non-emergency visits, and may inform future resource allocation and emergency service planning. However, as this was a retrospective single-center study, transfer of results to other settings must be done with caution.<\/jats:p>","DOI":"10.3390\/vetsci13090899","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T08:56:01Z","timestamp":1788339361000},"page":"899","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Urgency of After-Hours Presentations of Dogs and Cats to a Private Small-Animal Practice in Germany: A Retrospective Study of 4579 Visits"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-7623-4990","authenticated-orcid":false,"given":"Leoni","family":"Wizenty","sequence":"first","affiliation":[{"name":"Institute of Veterinary Epidemiology and Biostatistics, School of Veterinary Medicine, Freie Universit\u00e4t Berlin, 14163 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0064-1708","authenticated-orcid":false,"given":"Marcus G.","family":"Doherr","sequence":"additional","affiliation":[{"name":"Institute of Veterinary Epidemiology and Biostatistics, School of Veterinary Medicine, Freie Universit\u00e4t Berlin, 14163 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1111\/j.1476-4431.2012.00736.x","article-title":"Evaluation of a veterinary triage list modified from a human five-point triage system in 485 dogs and cats","volume":"22","author":"Ruys","year":"2012","journal-title":"J.
