Several forms of cardiac disease in the dog have now been demonstrated to inherited or "familial." These include both congenital and adult onset (often termed acquired) heart disease.
What is the most common congenital heart defect in dogs?
The most common congenital heart defects in dogs are patent ductus arteriosus (PDA), subaortic stenosis (SAS), pulmonic stenosis, and ventricular septal defect (VSD). Other heart conditions develop as the dog ages.
Can heart murmurs be hereditary in dogs?
As previously stated, heart murmurs can be genetic in dogs. There are many factors to consider as to whether the heart murmur is genetic or not. These factors include age, a heart defect in the family, and the predisposition of the breed.
Are heart defects hereditary?
Many cardiac disorders can be inherited, including arrhythmias, congenital heart disease, cardiomyopathy, and high blood cholesterol. Coronary artery disease leading to heart attack, stroke, and heart failure can run in families, indicating inherited genetic risk factors.
What is the most common cause of heart disease in dogs?
There's no single cause of heart disease in dogs. Aging, obesity, breed, and nutrition can all play a role. Heart valve problems are the most common issue and typically affect small breed dogs that are five years or older. No matter what heart condition your dog has, it's important to spot the signs early.
