@carlbick Ah, so you and Connie are not in Puerto Rico - for some reason I assumed you were. It's great that such organisations exist.
The health tests I was referring to are those for Fanconi and PRA which Basenjis do need their DNA checking for and which are additional to the normal health checks which would be expected from such a responsible organisation. They are equally essential in the case of Basenjis.
Which raises an interesting point - should they be done on dogs which are proven to have at least a mix of Basenji in their ancestry ? Fanconi, I would think possibly but not sure about PRA (progressive retinal atrophy).
In view of the similarity to a human's of the configuration of a Basenji's kidneys (the reason they were the subject years ago of so much research by Jackson Laboratories at Bar Harbor, Maine) I wonder if this 'difference' in Basenji kidneys is passed on in a mix ?
