The use of anesthesia in patients with endocrine diseases such as diabetes, hyperadrenocorticism and hyperthyroidism has become more common in recent years due to the advances and modernization that veterinary medicine has been undergoing. As a result, it is essential to recognize the physical changes that the disease can cause so that the patient receives the necessary support to stabilize him/her. When a patient undergoes a surgical-anesthetic intervention, it is essential to treat and control the disease whenever possible. Preoperative examinations will be necessary and will serve as the basis for calculating a personalized anesthesia protocol for the patient in question, as well as for the surgical procedure to which the patient will undergo. The patient's vital signs will be monitored continuously before anesthesia is actually administered and, once anesthesia has begun, this monitoring will be increased. By doing so, we do not completely eliminate the risks associated with anesthesia, but we significantly reduce them. As a result, even if intercorrelations do occur, we will be able to deal with them more quickly and effectively. In view of this, the aim of this study is to present the importance of all preparation for submitting diabetic dogs to any procedure, by reviewing the literature through scientific articles developed by professional researchers in the area, using CAPES, academic journals and Google Scholar as references. With the development of this study, it was possible to conclude that diabetic patients have their own particularities that should not be neglected, from their assessment of surgical risk to their postoperative period. Lack of knowledge in decision-making can lead to complications, putting their well-being and quality of life at risk.
