+++ You live(d) together with a heart sick Labrador Retriever? Please get in touch with us! +++
We have been asked multiple times from prospective dog owners as well as engaged breeders what kind of possibilities there are to decrease the probability of TVD to occur. That’s why we would like to summarize some tips in the following, which also apply on other (hereditary!) heart diseases.
Since the question of a possible genetic source of a heart disease is not clarified yet and therefore there is no gene test (yet?), there are the following ways (according to experts) to secure yourself as best as currently possible and to help containing heart diseases in Labrador Retriever.
The risk regarding the (continuing) breeding of dam/stud ('cardio - without findings') as well as siblings ('cardio - without findings') of affected dogs depends on the type of the heart disease. At this point the breeder should consider for further breeding that the dam/stud may be a carrier of the disease or at least talk to a cardiologist before further breeding.
Furthermore the distribution of information concerning possible heart diseases in Labrador Retriever as well as the planned study on tricuspid valve dysplasia in particular (e.g. linking on your own webpage) could be useful.
If you do own a Labrador Retriever affected by TVD or DCM, it would be very helpful to send in a blood sample from the affected dog for the planned studies of the Institute for Animal Breedings and Genetics of the University of Veterinary Medicine Hannover. Further information and contact info regarding these two research projects you can find here and here.
