Q. I have a boxer that is old and I think its not the age but he keeps fainting (already 2 times today) and I dont know what to do?

A. It is likely that he is suffering from so-called syncopes. Syncopes are caused when not enough oxygen reaches the brain and it then makes the dog (and people, too) faint. Syncopes happen, when an dog has a heart condition that compromises the oxygen-enriched blood to reach the brain. Boxers especially are prone to suffer from dilatative cardiomyopathy (DCM) where the heart muscle sort of gets thinner and stretches and the heart does not have the strength to pump the blood properly. You need to take him to the vet who, after making a diagnosis (likely blood tests, radiographs and ultrasound) will prescribe heart medications which help immensely.

A. Boxers are a breed which can be prone to developing irregular heart rhythms which can result in fainting episodes which are similar to fainting in people. Such episodes can result in significant disruption to the circulation and can be associated with loss of consciousness and occasionally sudden death. There are medications which can be used to help but these are not always 100% protective. I advise you video the episodes and get a full physical exam to rule out any other issues before considering any medications
