Ovarian Cancer in Dogs

Common info

There are 3 main kinds of ovarian tumors in dogs: epithelial tumors, germ cell tumors, and stromal tumors. The common symptoms of ovarian cancer in dogs include fever, lethargy, loss of appetite, weight loss, breathing difficulty, and vaginal discharge, etc.


The cause of ovarian cancer in dogs is unknown but often associated with the old-aged and non-spayed dogs.


Ovary is a vital organ in a female dog’s uterine cavity that produces eggs and female sex hormones. The tumors developed in an ovary may be either benign or malignant (cancer), which causes different effects on the body The epithelial tumors, often adenocarcinomas and papillary adenoma, influence the skins and tissues, the germ cell tumors attack the sperms and eggs. On the other hand, stromal tumors, upon malignant development, will cause an impact on the connective tissue. When pets get cancer, the cancerous tumor will start growing in the ovary, the organ from where it will spread to other parts of the body.

Treatment and Prevention

Regularly, a surgical removal of the benign tumor can complete without a problem. However, it may be more difficult in the case of malignant tumors as this involves the chance of infection and spread to other parts of the body.  Primarily, the veterinarian will have the pet spayed before removing the tumor. Along with the surgery, chemotherapy may also be applied to reduce the chance of the spread into other body organs.
