The article presents the results of studying the effects of humic substances in dogs with stage C myxomatous mitral valve degeneration receiving standard therapy according to the recommendations of the American College of Veterinary Internal Medicine. Comprehensive assessment of radiographic and electrocardiographic parameters before and after treatment was performed. It was found that adding humic substances to the standard therapy contributed to reducing heart size, decreasing pulmonary congestion and improving electrophysiological characteristics of the heart. The obtained results indicate the advisability of using humic substances as an additional tool in the complex treatment of dogs with myxomatous mitral valve degeneration.
