One of the major threats in canine health is a heart disease that can be acquired or congenital in nature.
Heart disease in dogs occurs mainly when normal blood flow is restricted when the dog’s heart valves do not close properly or the muscular walls of the dog’s heart are thinned and weakened.
Difficult breathing even while at rest, fainting, a loathing for exercise, loss of appetite, and weight loss are indicative of an impending heart failure.
