Approximately 20% of dogs aged 6 years and over 40 pounds had asymptomatic heart disease detectable by echocardiogram.

“one thing we we found though that was unexpected was that about 20% of dogs and that age and weight range actually have asymptomatic heart disease that you will see if you give them an echocardiogram but you won't detect from a stethoscope exam”

“if a vet with the stethoscope takes a heart murmur and then they give the dog an echocardiogram and they see regurgitation they'll call that heart disease if they don't hear a heart murmur nobody's gonna give their dog an echocardiogram right it's expensive yeah and so I'm not a cardiologist but I can't imagine the day would ever come we're using a stethoscope I could detect you know a low EF like to the tone of right yeah I mean unless you would not get that no no it's really the regurgitation their hearing is as a heart murmur and and that was most of most of the dogs that we ended up having to exclude we had to exclude because they had a pre-existing education that came out from the echocardiogram”
