Diseases that dogs are susceptible to if they are not sterilized:

1. Pyometra: Most of them occur in old dogs over 7 years old, and the incidence rate is similar in old female dogs that have not been sterilized. high. When this disease first occurs, there are often only symptoms of frequent thirst and frequent urination, and the owner does not pay much attention to it. If it is delayed for a long time, the body tissues will be damaged due to the absorption of bacterial endotoxins, and in severe cases, it may lead to kidney failure, which cannot be treated. Atretic pyometra that cannot drain out will cause peritonitis when the uterus ruptures due to collision or excess pus, which can quickly lead to death. In addition, the risk of anesthesia for old and sick dogs is high, and the cost of surgery and postoperative care is much higher than that of normal sterilization. Therefore, animals that are not intended to be bred are best sterilized as soon as possible.

2. Endometritis: Due to hormonal factors after estrus, the uterus is prone to infection, and a small amount of secretions can be seen clinically, which can be controlled with medication. However, dogs with this kind of system can easily become infected with pyometra, and surgical removal is the best option.

3. Breast tumors: Common diseases in older dogs that have not been neutered, and more than 50% of them are malignant tumors. Once it occurs, the chance of recurrence after removal is quite high. According to reports in the literature, the cause of this disease is related to hormones, and dogs neutered before one year old have almost no chance of it.

4. Ovarian cysts: Dogs will have persistent estrus, and some animals will have vaginal hyperplasia. Surgery to remove the ovaries can solve the problem.

5. Sexually transmitted diseases: Most are infected through mating. Sexual organ infection caused by mating, oral infection caused by licking diseased tissue, skin infection caused by wound contact, nasal infection caused by inhalation of tissue, or even brought into the abdominal cavity by surgical contamination. The dog has a foul odor and is extremely uncomfortable.

6. Prostatic enlargement: A common disease in elderly male dogs, which manifests as abdominal pain, difficulty urinating and even hematuria. The treatment is to sterilize to block male hormones and allow the glands to shrink naturally. Prevent the occurrence of this disease and eliminate the possibility of prostate tumors.

7. False pregnancy: Some female dogs will lactate and make nests after being in estrus, and they seem to be pregnant and about to give birth. This is a pathological reaction of hormonal abnormalities. If it happens frequently, only sterilization can prevent it.
