Does anybody know of any information re this as have a friend whose 6 month old boy looks although he may have the start of HD and wanted to send her some information about the breed avg scores etc.
According to the list at 10.10.01 (the latest I have) there were 301 Chesapeake's tested with a range of 0 - 61 and an Breed Mean Score of 11 (which had gone down)
