<結紮對公狗的好處> On the positive side, neutering male dogs 

•  eliminates the small risk (probably <1%) of dying from testicular cancer 

去除死於睪丸癌的風險 (原先機率約小於1%)

•  reduces the risk of non-cancerous prostate disorders 
非癌症攝護腺疾病風險降低

•  reduces the risk of perianal fistulas   

肛門瘻管風險降低

•  may possibly reduce the risk of diabetes (data inconclusive) 

可能降低罹患糖尿病的風險 (尚無定論)

<結紮對公狗的壞處> On the negative side, neutering male dogs   

•  if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a 

common cancer in medium/large and larger breeds with a poor prognosis.   

一歲前結紮，大幅增加骨癌的風險 (中大型犬常見但難以事先預測的疾病)

•  increases the risk of cardiac hemangiosarcoma by a factor of 1.6 

增加血管瘤的風險1.6倍

•  triples the risk of hypothyroidism  

甲狀腺機能減退風險增加三倍

•  increases the risk of progressive geriatric cognitive impairment  

漸進式老年認知功能損傷風險增加

•  triples the risk of obesity, a common health problem in dogs with many associated health problems 

肥胖風險增加三倍(肥胖是常見的健康問題，且會帶來更多相關的健康問題) 

•  quadruples the small risk (<0.6%) of prostate cancer  

前列腺癌風險增加四倍 (原先機率小於0.6%)

•  doubles the small risk (<1%) of urinary tract cancers   

尿道癌風險增加兩倍 (原先機率小於1%)

•  increases the risk of orthopedic disorders 

骨科疾病的風險增加

•  increases the risk of adverse reactions to vaccinations  

施打疫苗後的副作用風險增加



For female dogs, the situation is more complex.  The number of health benefits associated with spaying may 
exceed the associated health problems in some (not all) cases.  On balance, whether spaying improves the 
odds of overall good health or degrades them probably depends on the age of the female dog and the 
relative risk of various diseases in the different breeds.   

對母狗來說，情況較為複雜。在一些(並非全部)案例中，結紮是利多於弊。

站在中立的立場，結紮對於改善或降低整體健康的機率，要視母狗年齡與不同品種得各種疾病的相對風險而決定。

<結紮對母狗的好處> On the positive side, spaying female dogs 

•  if done before 2.5 years of age, greatly reduces the risk of mammary tumors, the most common 

malignant tumors in female dogs   

如2.5歲前結紮，大幅降低乳腺癌風險 (母狗最常見的惡性腫瘤)

•  nearly eliminates the risk of pyometra, which otherwise would affect about 23% of intact female 
dogs; pyometra kills about 1% of intact female dogs 

幾乎去除子宮蓄膿的風險 (子宮蓄膿影響23%的母狗，致死率1%)

•  reduces the risk of perianal fistulas   

肛門瘻管風險降低

•  removes the very small risk (≤0.5%) from uterine, cervical, and ovarian tumors 

去除尿道、子宮頸與卵巢腫瘤的微小風險 (原先機率小於等於0.5%)

<結紮對母狗的壞處> On the negative side, spaying female dogs  

•  if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a 

common cancer in larger breeds with a poor prognosis   

一歲前結紮，大幅增加骨癌的風險 (大型犬常見但難以事先預測的疾病)

•  increases the risk of splenic hemangiosarcoma by a factor of 2.2 and cardiac hemangiosarcoma by 
a factor of >5; this is a common cancer and major cause of death in some breeds

脾臟血管肉瘤風險增加2.2倍，心血管肉瘤風險增加超過5倍 (常見的癌症且為某些品種的致死原因)

•  triples the risk of hypothyroidism 

甲狀腺機能減退風險增加三倍

•  increases the risk of obesity by a factor of 1.6-2, a common health problem in dogs with many 

associated health problems  

肥胖風險增加1.6~2倍 (常見的健康問題，且會帶來更多相關的健康問題) 

•  causes urinary “spay incontinence” in 4-20% of female dogs  

導致4~20%的母狗尿失禁

•  increases the risk of persistent or recurring urinary tract infections by a factor of 3-4 

持續性或經常性尿道感染風險增加3~4倍

•  increases the risk of recessed vulva, vaginal dermatitis, and vaginitis, especially for female dogs 
spayed before puberty 

外陰部炎、陰道皮炎和陰道炎風險增加，特別是在青春期前就已結紮的母狗

•  doubles the small risk (<1%) of urinary tract tumors  

尿道腫瘤風險增加兩倍(原先機率小於1%)

•  increases the risk of orthopedic disorders 

骨科疾病風險增加

•  increases the risk of adverse reactions to vaccination 

施打疫苗後的副作用風險增加
