There have recently been two articles in the US, Retriever News, on TVD.
A couple of years ago, I went to a large Labrador retriever colony breeding establishment health conference, where TVD was discussed openly (as some breeding studs and dams were found when echoed, had the condition). They did not consider TVD widespread in their breeding colony.
The cardiologists confused me, as one thought the trait dominant, one recessive. Two geneticists suggested we don't have to worry about the condition as multiple genes are involved, and considered rare.
What are your thoughts?
Should all breeding stock especially studs have clear echocardiograms?
