Metaphyseal osteopathy (MO) was diagnosed in three Australian Kelpie puppies that were presented for veterinary assessment of lameness. The three puppies were siblings. Each was from a different litter by the same breeding pair. The puppy in case one was seen by the authors, and the puppies in cases two and three were patients at other veterinary hospitals. However, the medical records and radiographs were examined and reviewed for this report. Radiographic investigation of the lameness revealed pathognomonic appearance of MO affecting the metaphyseal region of the long bones in all three puppies. The diagnosis was confirmed on histopathology in one patient.
MO is considered a disease of large and giant-breed dogs, being rarely reported in non-large-breed dogs, and has not been reported in the Australian Kelpie, which is considered a medium-breed dog. This case series suggests a previously unreported breed predisposition to MO in the Australian Kelpie.
三只澳大利亚凯尔皮幼犬因跛行前来接受兽医评估，被诊断为干骺端骨病（MO）。这三只幼犬是同胞。每只都来自同一繁殖对的不同窝。病例一的幼犬由作者诊治，病例二和病例三的幼犬是其他兽医医院的患者。然而，本报告对病历和X光片进行了检查和回顾。对跛行的X光检查显示，所有三只幼犬的长骨干骺端区域均出现了MO的特征性表现。其中一只幼犬经组织病理学确诊。
MO被认为是大型和巨型犬种的疾病，在非大型犬种中很少报道，在被认为是中型犬种的澳大利亚凯尔皮犬中尚未有报道。本病例系列表明澳大利亚凯尔皮犬对MO存在此前未报道的品种易感性。
