Cancer is one of the biggest health problems in animals and one of the main causes of death in dogs and cats, becoming increasingly common in clinical medicine, especially in geriatric patients. Treatments with fewer adverse effects, aiming at better quality of life and physical and emotional well-being, make integrative and complementary care for cancer grow every day, including homeopathy. In oncology, homeopathy is used alone or as a complement to traditional treatments, with many benefits to animals, hoping to reduce the side effects of antineoplastic drugs and the clinical signs of the disease. In addition, it is a treatmentmethod with little or no side effects, safe and effective, it is not invasive, the form of administration is simple, highly palatable, increasing its acceptance. It has a good cost-benefit ratio and the lack of an accurate diagnosis does not represent an impediment to starting treatment with homeopathic medicines. Thus, the objective of this work is to explore, as proven through bibliographical analysis, the benefits of homeopathy in veterinary oncology.
