Ultrasonography revealed three individual placental sites in progressed resorption and two vital adequately developed foetuses sharing a joint placenta. On days 41 and 48\u00a0p.ov., sonographic signs indicated normal development of both foetuses, but on day 52\u00a0p.ov., both foetuses were found to be dead. A caesarean section was performed the same day. Examination of the removed uterus confirmed the diagnosis of a \u201ctwin\u201d pregnancy with two foetuses sharing the same placental site but separate amniotic membranes. One foetus showed generalized oedema (anasarca). Bacterial culture of swabs taken from inside the placental cavity was negative. At histological examination of the uterus, no signs of inflammation were found. Serum relaxin concentrations (day 38, 41, 48 and 52.\u00a0p.ov.) were consistent with those of bitches with normal pregnancies. Cytogenetic analysis of the two foetuses revealed dizygotic twins, one male and one female according to SRY\u2010PCR. By genotyping 17 high\u2010polymorphic canine microsatellites, it could be demonstrated that the two foetuses developed from two different oocytes.<\/jats:p>","DOI":"10.1111\/rda.12869","type":"journal-article","created":{"date-parts":[[2016,11,18]],"date-time":"2016-11-18T23:36:52Z","timestamp":1479512212000},"page":"140-143","source":"Crossref","is-referenced-by-count":3,"title":["Monochorial diamniotic dizygotic twins in a German Shepherd Dog: A case report"],"prefix":"10.1111","volume":"52","author":[{"given":"C","family":"Urhausen","sequence":"first","affiliation":[{"name":"Unit of Reproductive Medicine of Clinics \u2013 Small Animal Clinic University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K","family":"Wolf","sequence":"additional","affiliation":[{"name":"Unit of Reproductive Medicine of Clinics \u2013 Small Animal Clinic University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Beineke","sequence":"additional","affiliation":[{"name":"Institute for Pathology University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Dierks","sequence":"additional","affiliation":[{"name":"Institute for Animal Breeding and Genetics University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Schmicke","sequence":"additional","affiliation":[{"name":"Clinic for Cattle Laboratory for Endocrinology University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Einspanier","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine Institute of Physiological Chemistry University of Leipzig  Leipzig Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AR","family":"G\u00fcnzel\u2010Apel","sequence":"additional","affiliation":[{"name":"Unit of Reproductive Medicine of Clinics \u2013 Small Animal Clinic University of Veterinary Medicine Hannover  Hannover Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,11,18]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/dei379"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(95)90011-X"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.34438"},{"key":"e_1_2_6_5_1","first-page":"663","article-title":"Perinatal problems in multiple births","volume":"107","author":"Dudenhausen J.
