Health testing is a very important part of breeding boxers and more people need to be aware. This page provides an explanation of genetic disease and descriptions of those diseases prevalent in boxers, followed by a list of the tests available to screen for those diseases and determine genetic fitness for breeding.
The American Boxer Club’s recommended health screening programme for breeding boxers can be viewed at

What is a genetic disease?
A genetic disorder is one in which an abnormality in the genetic make-up (the genome) of the individual plays a significant role in causing a disease or condition. While some disorders can occur as the result of spontaneous mutation, most genetic disorders are inherited.
These diseases are heart-breaking because they can impact severely on the quality and length of life of the affected dog - who is generally a well-loved family member by the time the condition is apparent.
The frequency of inherited conditions can be greatly reduced through good breeding practices. For this to occur, we need to know how the disease is inherited, how to identify the condition as early as possible, and ways to recognize carriers of the disease who are not clinically affected. Where testing regimes are available, it is important that all potential breeding stock are screened.
Animals found to be affected by, or are carriers of a disease should not used for breeding.
Genetically inheritable diseases prevalent in boxers
Aortic stenosis/sub-aortic stenosis (AS/SAS) is one of the most common heart defects occurring in boxers. Stenosis is narrowing of the aorta, right below the aortic valve, which forces the heart to work harder to supply blood. Reduced blood flow can result in fainting and even sudden death. The disease is inherited but its mode of transmission is not known at this time. Diagnosis must be made by a veterinary cardiologist, after detection of a heart murmur.
Breeding dogs must be properly screened for this disease and affected dogs must not be bred from.
Boxer cardiomyopathy is an electrical conduction disorder which causes the heart to beat erratically (to have an arrhythmia) some of the time and can result in weakness, collapse or sudden death. These arrhythmias are difficult to detect with any certainty by listening to the heart with a stethoscope, unless they are very frequent thus the first sign of the disease may be fatal. Cardiomyopathy is a genetically inheritable condition with devastating results.
Because a dog cannot be cleared of cardiomyopathy by a routine veterinary examination and the disease may not show itself until after a dog reaches breeding age, it is important that all breeding stock are properly screened for this disease.
Boxer cardiomyopathy is a distinct disease from the dilated cardiomyopathy common in some other breeds. Other names for BCM are Boxer Arrythmic Cardiomyopathy (BAC), Familial Ventricular Arrhythmia (FVA) and Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC).
