There were few differences between diet groups at baseline, with congestive heart failure and arrhythmias common in both groups. Thirty-four dogs with known baseline diet and diet change status had follow-up echocardiograms between 60 and 1,076 days later (traditional diet, n = 7; nontraditional diet that changed diets, 27; and nontraditional diet group without diet change, 0). Dogs in the nontraditional diet group that changed diets had a significantly greater decrease in normalized left ventricular diameter (diastolic, <jats:italic>P<\/jats:italic> = .02; systolic, <jats:italic>P<\/jats:italic> = .048) and the left atrium-to-aorta ratio (<jats:italic>P<\/jats:italic> = .002) and a significantly greater increase in fractional shortening (<jats:italic>P<\/jats:italic> = .02) compared to dogs eating traditional diets. Dogs eating nontraditional diets with diet change (n = 45; <jats:italic>P<\/jats:italic> &lt; .001) and dogs eating traditional diets (12; <jats:italic>P<\/jats:italic> &lt; .001) had a significantly longer survival time compared to dogs eating nontraditional diets without diet change (4).
