Cough is a clinical symptom of numerous pathologies that affects dogs and has several causes, causing discomfort, pain and stress to the animal. Neural Therapy consists of a regulatory treatment that seeks to activate the patient's self-healing process, using local anesthetics in low concentrations and the areas chosen for treatment are according to life history. It is a widespread treatment in many countries, however, in Brazil, it has a relatively recent origin. It was introduced in South America in 1970 by a Colombian doctor trained in Germany, Germán Duque and disseminated by Júlio Cesar Payan, a current reference in Colombian Neural Therapy. The objective of this work is to demonstrate the effectiveness of the treatment in an elderly canine that had a chronic cough unresponsive to other types of treatment.
