A weak-hearted dog tires easily, with panting, weakness, fast breathing, cough and reluctance to move after little activity, and may have breathing difficulty or cardiac arrest if overexerted or emotional. Obese, old or congenitally affected dogs are prone.
If these signs appear, have regular veterinary checkups.
