Neuroendocrine tumors are a group of tumors that develop from the cells of the neuroendocrine system, and include insulinomas, gastrinomas, glucagonomas, carcinoids, medullary thyroid carcinomas, small-cell lung carcinomas, pheochromocytomas, chemodectomas, and Merkel cell carcinomas. Some of these tumors are functional, while others are non-functional. The signs of disease in dogs and cats depend on the type of growth, location of the tumor, its size, the degree of infiltration in the surrounding tissues, whether it has metastasized, and whether it is functional. A definitive diagnosis requires tissue biopsy and histopathology, often with histochemical staining and electron microscopy. Staging is highly recommended for these tumors. Treatment may involve surgery, chemotherapy, radiation therapy, and medical and dietary management.

Neutering and castration are the common terms used to describe the surgical procedure during which both testicles are removed to sterilize a male dog. The consensus at this time is that neutering will increase the lifespan of a dog. It is also a vital step in reducing the overpopulation of dogs and the crowding of shelters. This operation requires general anesthesia and complications are rare. A rest period of 5–10 days is needed for recovery after surgery.

The term 'nutraceutical' was coined to represent compounds found in food and herbs that are not technically considered nutrients, such as vitamins or minerals, but may have a profoundly beneficial impact on the health of the body. Common examples of nutraceuticals include glucosamine, which is used in the treatment of arthritic conditions for both dogs and cats, and antioxidant compounds, that help in the prevention of cancer.
