Pets are living longer. Consequently, they are more predisposed to diseases with advancing age, to the detriment of the lifestyle to which they are submitted. Sometimes these diseases can not be treated surgically and/or are difficult to control due to concomitant comorbidities that limit the execution of anesthetic and surgical procedures. Under this perspective, other therapies should be considered to treat these diseases, aiming to control, provide relief, and even cure, such as total remission in cases of various tumors. Homeopathy, a therapy enunciated by Hahnemann, relieves clinical signs, promoting a better quality of life, especially for those who no longer find alternatives in conventional treatments. This study reports the treatment of a tumor in an elderly male dog using oral and injectable homeopathic medicines. The tumor was located in the right lower lip, near the labial commissure, and showed complete remission on April/2020. This patient was followed up until his death in August 2022, with no recurrence of the initial complaint. According to clinical results, the homeopathic therapy was effective in its purpose, reestablishing the patient's health conditions. Despite being an elderly animal and its slow biological response, the treatment was successful.
