Uterine Cancer in Dogs

Common info

Uterus is a vital organ of the female dog. When tissues grow abnormally, a tumor either benign tumor or a malignant will develop on the smooth muscles of the dog’s uterus and endometrium. However, benign tumors commonly exist. The symptoms of uterine cancer in dogs are difficulty in urination, blood in urine, loss of appetite, weight loss, constipation, and leucorrhea, etc.


Causes of uterine cancer in dogs are still unknown, but the disease is more prone to occur in the unspayed female dogs.


There are two types of cancers found in dogs; a benign tumor called leiomyomas and leiomyosarcomas, a malignant tumor. Both exist in the smooth muscles of the uterus, which will be gradually formed into a large-sized tumor and compress other abdominal organs, including the stomach, intestine, and bladder, causing the abdomen to expand apparently.  All these will weaken the uterus, making it easily contagious if not being treated.

Treatment and Prevention

The best treatment is neutering. However, chemotherapy is also essential as it can reduce the probability of the spread of disease to other parts of the body. For medication, a vet may prescribe doxorubicin, cisplatin, carboplatin, and epirubicin for infection cases, where inflammations are in the uterus. Also, antibiotics may be another option to prevent bacterial infection.
