Description
Nantawan Yatbantoong, Nattaphol Muangthong, and Soontaree Petchdee compared heart structure in 2026 between indoor pet dogs, active farm dogs, and indoor dogs with heart disease. They asked whether an active life reshapes the canine heart. Thirty-nine client-owned dogs received physical exams, electrocardiograms, and heart ultrasounds, and the three groups were compared on chamber sizes and function.
Farm dogs showed lower resting heart rates and a stretched, thinner-walled main pumping chamber, a pattern consistent with exercise adaptation rather than disease. Diseased dogs instead showed an enlarged upper chamber and different function measures. Farm dogs were also younger and heavier, which clouds the comparison. The authors stress that ultrasound remains essential to tell healthy adaptation from real disease.
