绝育手术对宠物而言是好的 Sterilization is good for Pet

绝育手术对动物而言是好的：绝育可避免动物因性挫折而制造各种问题，主人不会因那些问题而嫌弃宠物，进而有弃养的念头，因此绝育对动物而言绝对是好的。
此外，手术还可避免某些疾病的发生，如：子宫蓄脓、卵巢囊肿引起的疾病、性病、前列腺肿大等问题。一岁前即手术还可以避免乳房肿瘤发生的可能。性荷尔蒙会引起动物的不安，性挫折常见心理的不适应状况，包括：咬人、破坏家具或坏脾气等后果发生，绝育可帮助动物克服这些问题。绝育对动物而言，当然是 利多于弊。
Sterilization is good for animals: Neutering animals can help to avoid various problems caused by sexual frustration. Owners don’t have to get frustrated with the pets when their pets have health issues and eventually decides to abandon them. In other words, neutering is for the best of your pets.
Besides that, the surgery helps to prevent some disease, e.g. Pyometra, ovarian cysts, STD, prostate enlargement, etc. Neutering before your pet first birthday may even help in preventing breast cancer. Sex hormones will cause anxiety, it is very common for animals to become aggressive towards people or objects (attacking people, destroying your furniture or bad temperament). Neutering them would help to overcome these sorts or behavior hence it has more pros than cons, either to the animals themselves or to the pet owners.

未绝育动物的常见病：
1.子宫蓄脓：多数发生于7岁以上老狗，未绝育的老年母狗发生率相当高。此病往往刚发生时只有频渴频尿的症状，如果不是开放型流出大量分泌物，主人不会太注意。拖延久了，身体组织会因吸收细菌内毒素造成伤害，严重时引发肾衰竭，无法救治。流不出来的闭锁型子宫蓄脓会在子宫因碰撞或脓汁过多破裂时，引发腹膜炎，迅速致死。
此外，老狗、病狗麻醉风险大，手术及术后照顾也比正常的绝育费用高出很多，因此不打算让它繁殖的动物最好尽早绝育。
Common diseases found in animals especially dogs: -
1. Pyometra: it is often seen in senile bitch (more than 7 years old) that are not neutered. The symptoms could be as mild as increased drinking and urinating. The most obvious symptom of open pyometra is a discharge of pus from the vulva (in a Female) that has recently been in heat. However, symptoms of closed pyometra are less obvious and it can be easily missed. When the cervix is fully closed (closed pyometra), there is no discharge from the vulva, and like in appendicitis, the uterus may rupture and pus escapes into the abdomen, causing peritonitis and possible rapid death.
Besides, senile dogs and ill dogs are exposed to higher risks during anesthesia. The surgery itself (neutering) and postoperative care usually costs more than the normal need neutering (done when the dog is young and healthy). Therefore, if you have no intention in letting your dogs breed, you should make arrangement to neuter them ASAP.

2.子宫内膜炎：发情过后因荷尔蒙关系，子宫容易感染，临床可见少许的分泌物，可用药控制，但此种体制动物很容易变成子宫蓄脓感染的病例，手术切除是一劳永逸的解决办法。
2. Patients with endometriosis: After a bitch has been in heat, its uterus is very vulnerable to infection. Discharge from the vulva is often observed, which can be controlled with medications. However, this could lead to Pyometra, hence neutering is the permanent solution.

3.乳房肿瘤：未绝育的老年动物常见病，在狗约50%以上是恶性肿瘤。一旦发生，切除后再复发的机会相当高。据文献报道，这种病诱因与荷尔蒙有关，一岁以前绝育的动物几乎没有发生的可能。
3. Breast tumor: breast tumors often develop in senile animals. Approx. 50% found in dogs are cancerous. Even after removal of the tumor, the chances of reoccurrences are very high. According to literature, the production of estrogen has a lot to do with the formation of this type of tumors. Therefore, neutering your dogs before they turn one is a recommended solution.

4. 卵巢囊肿：动物会有持续性发情的现象，有些动物会有阴道增生的现象。开刀切除卵巢才能解决问题。
4. Ovarian Cysts: animals tend to go into heat frequently, sometimes continuously. Some animals may experience Vaginal hyperplasia. The removal of ovaries will solve this problem before it occurs.

5.性病：多数由交配而感染。由交配引起性器官感染、因舔到病变组织而口腔感染、由伤口接触而皮肤感染，由吸入组织而鼻腔感染，甚至由手术污染带入腹 腔……动物身上有血腥恶臭味，极不舒服。
5. Canine transmissible Venereal disease: majority of the disease are spread by sexual contact. The infections commonly came from mating, licking of diseased tissue could cause oral infection, through open wounds, through inhaling tissues that causes nasal infection, even contamination during surgery that causes abdominal infection… animals with this often smell very bad and they are in constant severe discomfort.

6.前列腺肿大：老年公狗常见的疾病，表现为腹痛、排尿困难、甚至血尿，治疗办法是绝育阻断雄性激素，让腺体自然萎缩。防止此病的发生，并杜绝前列腺肿瘤 发生的可能。
6. Prostate diseases: this disease is often found in senile male dogs. Symptoms include blood in the urine and straining to urinate and defecate. Neutering is the treatment recommended so that the androgens can be eliminated, causing the glands to atrophy naturally, preventing the disease and the development into prostate cancer.

7.假孕：有些母犬在发情过后会有泌乳、做窝现象，似乎已经怀孕即将产子。这是荷尔蒙不正常的一种病态反应。如经常发生，惟有绝育可以杜绝。
7. False pregnancy (pseudocyesis): is a common condition in female intact dogs. Symptoms include swelling of the mammary glands, lactation, not eating, and "mothering" small objects, indicating pregnancy and looking like the litter is due anytime soon. If this occurs frequently, neutering can help solve the problem.

8.睾丸肿瘤：隐睾未绝育的雄性动物上了年纪后，未下降到阴囊的睾丸常会变成肿瘤组织，而且隐睾本身有遗传性，因此建议给这类动物绝育。
8. testicular cancer: Senile dogs that have Cryptorchidism and not been neutered are prone to testicular torsion and testicular cancer, so these dogs should be castracted to prevent problems later. Also, dogs with Cryptorchidism must not breed.
