The vertebral columns of 115 dachshunds were x-rayed at 1 and 5 years of age. This sample represented 5.7% of all dachshunds registered with the Norwegian Kennel Club in the period 1986-1988. All dogs were clinically normal at the commencement of the study. At 1 year of age calcified intervertebral discs were identified in 34 (29.6%) of the dogs and the number of calcified discs in each individual varied from 1 to 7 with a mean of 2.7. At 5 years of age calcified discs were identified in 66 (57.4%) of the dogs and the number of calcified discs in each individual varied from 1 to 11 with a mean of 3.2. Of all dogs in which calcified discs were identified at 1 year of age, 33 (97.1%) were found to have calcified discs also at 5 years of age. Of 92 calcified discs identified in the dogs at 1 year of age, 29 (31.5%) were not calcified 4 years later. Of 211 calcified discs identified in the dogs at 5 years of age, 148 (70.1%) were not calcified 4 years before. From 1 to 5 years of age, signs of spinal disease were registered in 12 (35.3%) of the dogs in which calcified discs were identified at 1 year of age, and in 7 (8.6%) of the dogs in which calcified discs were not identified at 1 year of age. Of all dogs in which one or more calcified discs had disappeared during the study-period, signs of spinal disease were registered in 9 (75.0%).
对115只腊肠犬在1岁和5岁时进行了脊柱X光检查。该样本占1986 - 1988年期间在挪威养犬俱乐部登记的所有腊肠犬的5.7%。在研究开始时，所有犬只临床均正常。1岁时，在34只（29.6%）犬只中发现了钙化椎间盘，每只犬的钙化椎间盘数量从1个到7个不等，平均为2.7个。5岁时，在66只（57.4%）犬只中发现了钙化椎间盘，每只犬的钙化椎间盘数量从1个到11个不等，平均为3.2个。在1岁时发现有钙化椎间盘的所有犬只中，33只（97.1%）在5岁时也被发现有钙化椎间盘。在1岁时犬只身上发现的92个钙化椎间盘中，4年后有29个（31.5%）未钙化。在5岁时犬只身上发现的211个钙化椎间盘中，4年前有148个（70.1%）未钙化。从1岁到5岁，在1岁时发现有钙化椎间盘的犬只中有12只（35.3%）出现了脊柱疾病症状，在1岁时未发现钙化椎间盘的犬只中有7只（8.6%）出现了脊柱疾病症状。在研究期间，有一个或多个钙化椎间盘消失的所有犬只中，9只（75.0%）出现了脊柱疾病症状。
