A chemodectoma is a type of tumor made up of chemoreceptor cells. Chemoreceptor cells detect chemical changes in the body and respond by regulating chemical or physical processes. These tumors are most often seen along one of the carotid arteries and the aorta. Brachycephalic breeds are more predisposed to these types of tumors, though they may occur in any dog breed. These tumors are usually locally aggressive, however, there are rare cases of metastasis to other organs, including the lungs, lymph nodes, and bone.

Chemotherapy is the therapeutic use of chemical agents to destroy or inhibit the growth and division of cancer cells. Usually, chemotherapy is used when tumors are widespread or when there is significant or immediate risk of spread from the primary location. It is often used following the surgical removal of tumors. In some cases, chemotherapy is started prior to surgery. The side effects of chemotherapy are related to the effects of chemotherapy on normal -as well as cancerous- cells. The principal goal of cancer care in pets is to provide cancer control without reducing quality of life.
