I don't know about a forum…but here is :Svenska Basenji sallskapets" website..http://www.basenji.se/
lots of info available as well as links to all the breeders that follow certain SKK guidelines.
There are also guidelines available as to what diseases basenjis might be prone to..
As far as health testing the more the merrier, in my opinion…but for sure Fanconi, eyes would be nice and hips are a plus....and remember ask questions, see if you can visit breeders and hang with them and their dogs..there are a few breeders in the middle and a little north but most of them are in the south it seems.
