Why is a three-year-old heart worse than a bear?

Due to genetic restrictions, they are likely to suffer from congenital heart disease.

Cardiac hypertrophy is a headache for many parents. This is the most common heart disease in all dogs. Especially small dogs such as Bomei, Teddy, Maze and Chihuahua, they are as high-risk as old dogs. But because of this, parents can't rush to the hospital. Cardiac hypertrophy does not mean that dogs are "sentenced to death".

Congenital inherited heart problems or tracheal defects are very likely to lead to heart problems, such as mitral insufficiency, reflux, tracheal collapse, stenosis and so on. This kind of congenital heart disease problem will become more and more obvious with the increase of dog age. The most typical breed is Bomei, and its heart attack rate is as high as 70%.

The causes of acquired myocardial hypertrophy are more complicated and diverse, among which obesity and hypertension are the most common. Because overweight exceeds the dog's physical load, the heart burden is heavy, leading to heart disease; In addition, hypertension will increase the blood flow and pressure of dogs, and make the muscles in the dog's heart lose some elasticity, which will lead to cardiac hypertrophy.
