Forty-seven placentas were obtained from 18 bitches that underwent emergency cesarean sections. For descriptive purposes, the cases were classified into four groups based on the duration of dystocia: Group A, up to 6 h; Group B, 6\u201311.9 h; Group C, 12\u201324 h; and Group D, more than 24 h. Forty-seven placentas were studied. Both macroscopic and microscopic characteristics were evaluated in each placenta. Descriptive data were presented, and logistic and multinomial regression models were used to assess whether dystocia duration (in hours) is associated with the presence and severity of placental macro- and microscopic lesions. An hour increment over the mean in the duration of dystocia showed a non-significant trend to increasing the presence of macroscopic necrosis (OR: 1.11, p = 0.09) and mineralization (OR: 1.10, p = 0.06), and it also increased the severity of macroscopic congestion (OR: 1.44; p = 0.01) and showed a non-significant trend to increasing the severity of polymorphonuclear neutrophil infiltrate (OR: 1.18; p = 0.06). These findings highlight the importance of early obstetric intervention in all cases of dystocia to minimize fetal hypoxia and improve neonatal outcomes. Moreover, the placenta could serve as a biomarker for fetal distress, as the presence of severe lesions indicates an increased risk for reduced neonatal survival.<\/jats:p>","DOI":"10.3390\/life16020349","type":"journal-article","created":{"date-parts":[[2026,2,18]],"date-time":"2026-02-18T12:59:16Z","timestamp":1771419556000},"page":"349","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Dystocia Duration on the Placental Health in Canines"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0333-5274","authenticated-orcid":false,"given":"Romina Gisele","family":"Praderio","sequence":"first","affiliation":[{"name":"Instituto de Investigaciones en Reproducci\u00f3n Animal (INIRA), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, La Plata 1900, Argentina"},{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), Godoy Cruz 2290, CABA 1425, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3235-3711","authenticated-orcid":false,"given":"Mauricio Javier","family":"Giuliodori","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones en Reproducci\u00f3n Animal (INIRA), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, La Plata 1900, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9417-9560","authenticated-orcid":false,"given":"Rodolfo Luzbel","family":"de la Sota","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones en Reproducci\u00f3n Animal (INIRA), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, La Plata 1900, Argentina"},{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), Godoy Cruz 2290, CABA 1425, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7285-1814","authenticated-orcid":false,"given":"Mar\u00eda Alejandra","family":"Stornelli","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones en Reproducci\u00f3n Animal (INIRA), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, La Plata 1900, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1016\/j.theriogenology.2019.02.009","article-title":"Identifying risk factors for canine dystocia and stillbirths","volume":"128","author":"Cornelius","year":"2019","journal-title":"Theriogenology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"117677","DOI":"10.1016\/j.theriogenology.2025.117677","article-title":"Placental and other risk factors related to the survival and development of neonates from birth up to 10 days of life in bitches","volume":"249","author":"Praderio","year":"2026","journal-title":"Theriogenology"},{"key":"ref_3","unstructured":"Gill, M.A. (2001).
