Effects of Neutering in German Shepherd Dogs

Datasets used to study the effects of neutering (including spaying) in increasing the incidence of joint disorders and cancers in German Shepherd Dogs. Veterinary hospital records from the University of California, Davis were examined over a 14.5-year period for the effects of neutering during the specified age ranges: before 6 mo., and during 6-11 mo., during 1 year and in years 2 through 8. The diseases examined were hip dysplasia, CCL tear, elbow dysplasia, lymphosarcoma, mast cell tumor, hemangiosarcoma, osteosarcoma, mammary cancer, pyometra, urinary incontinence, and degenerative myelopathy.

本数据集用于研究绝育手术（含卵巢子宫摘除术）对德国牧羊犬关节疾病与癌症发病率的影响。研究人员在14.5年的时间跨度内，对加利福尼亚大学戴维斯分校（University of California, Davis）的兽医院病历展开分析，针对6月龄前、6至11月龄、1岁时以及2至8岁期间接受绝育手术的犬只，考察其绝育行为的相关影响。本次研究涉及的疾病包括髋关节发育不良、前十字韧带（CCL）撕裂、肘关节发育不良、淋巴肉瘤、肥大细胞瘤、血管肉瘤、骨肉瘤、乳腺癌症、子宫蓄脓、尿失禁以及退行性脊髓病。
