Abstract Background Hypomagnesemia is associated with a poor prognosis in humans with congestive heart failure (CHF), but studies in veterinary medicine are limited. Hypothesis Serum ionized magnesium concentration [iMg2+] would decrease as CHF progresses compared with the initial diagnostic levels and that lower [iMg2+] would be negatively associated with prognosis in dogs with CHF. Animals A total of 181 client‐owned dogs with myxomatous mitral valve disease (MMVD) were included. They were classified into the preclinical stage (NO‐CHF, n = 108), stage C (n = 42), and stage D (n = 31) based on the American College of Veterinary Internal Medicine MMVD classification. Methods This is a retrospective study from 2 referral centers. The [iMg2+] was compared among the NO‐CHF, stage C, and stage D groups. Kaplan‐Meier curves and the log‐rank test were used to compare the incidence of death between groups. Multivariable Cox regression analysis was used to estimate the association of hypomagnesemia with the death. Results In the stage D group, the [iMg2+] was lower than that in the NO‐CHF (P
