胎兒位置、姿勢或方向異常導致難產。正常為頭部或後肢先出，頭部朝向產道。異常胎位需人工矯正或剖腹產。
Queens are induced ovulators; pseudopregnancy is less common than in dogs. Pyometra can occur after exogenous progesterone administration. Mammary hyperplasia (fibroadenomatous change) is common in young intact or progestin-treated queens and is self-limiting after OHE.
Pyometra is a common emergency in intact female dogs, typically occurring 4-8 weeks post-estrus during diestrus. Ovariohysterectomy is the treatment of choice. Benign prostatic hyperplasia (BPH) is nearly universal in intact male dogs over 5 years of age.
建議：LRS 維持量 + 矯正脫水（pyometra/dystocia 常有脫水）
類型：LRS
監測頻率：每日（術後）
建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
早期識別及處理預後良好。延遲可能導致胎兒死亡及母體併發症。
