研究发现,包括北京和奇瓦瓦在内的12个狗种由于面部平坦而面临呼吸困难的高风险。 12 dog breeds, including Pekingese and Chihuahuas, face high risk of breathing issues due to flat faces, study finds.

对近900只狗进行的一项新研究发现,包括吉娃娃、北京人、Shih Tzus和波士顿梯子在内的12种品种具有中高或中度的中枢脑积裂阻塞性空气通道综合症(BOAS)风险,这是一种呼吸障碍症,与短鼻、狭小鼻孔和扁脸有关。 A new study of nearly 900 dogs identifies 12 breeds, including Chihuahuas, Pekingese, Shih Tzus, and Boston terriers, as being at high or moderate risk for brachycephalic obstructive airway syndrome (BOAS), a breathing disorder linked to short snouts, narrow nostrils, and flat faces. 超过80%的北京人和日日本国人表现出了BOAS的迹象,而其他品种的发病率在25%至75%之间。 Over 80% of Pekingese and Japanese Chin showed signs of BOAS, while other breeds had rates between 25% and 75%. 肥胖症和极端身体特征使这种状况恶化,在锻炼、睡眠和热中会造成呼吸问题。 The condition, worsened by obesity and extreme physical traits, can cause breathing issues during exercise, sleep, and in heat. 研究人员敦促所有者从经健康检验的父母中选择小狗,并支持育种改革,以减少极端特征。 Researchers urge owners to choose puppies from health-tested parents and support breeding reforms to reduce extreme features. 肯内尔俱乐部正在扩大其BOAS测试方案,以包括这些品种。 The Kennel Club is expanding its BOAS testing program to include these breeds.
