軟骨發育不全為骨骼軟骨內化骨異常導致四肢短小的先天性骨骼畸形。部分犬種（臘腸犬、巴塞特獵犬）的短肢體型即為軟骨發育不全的品種選育結果。非預期的軟骨發育不全則可導致嚴重骨骼異常。
臘腸犬、巴塞特獵犬為「正常」品種特徵。其他品種的軟骨發育不全為病理性。

這頁有幾個欄位是同系統共用的模板，還沒針對本疾病單獨改寫過。請以臨床判斷為準，記得對照下方文獻。
建議：術後維持量 LRS 或 Plasmalyte，恢復進食後可停止
類型：LRS
監測頻率：每日（術後）；每次回診

穩定但需注意惡化徵兆，建議安排近期門診 (stable but monitor for deterioration, schedule near-term visit)
作為品種特徵的軟骨發育不全壽命正常。病理性者視畸形嚴重程度與併發症而定。
Diagnostic Approach for Chondrodysplasia
Gait analysis, joint palpation, range of motion assessment, muscle mass comparison
Minimum 2 orthogonal views of affected region; compare contralateral side if needed
Joint fluid analysis, CT for complex fractures, arthroscopy if indicated
