I live in the same area as @jblair814 and the dog rescues here will neuter any pup before letting you adopt them. The same goes for some of the basenji breeders nearby, they will neuter the pups at around 11 or 12 weeks before letting you adopt them.
@tanza Yes I checked the site and the breeder did do the test for Fanconi (most dogs clear and a few carrier) and the Eyes (normal) but not the rest (hips, thyroid). I noticed the history for the dogs was available, some of the grandparents had all the tests done with thyroid being normal and hips being excellent. I also met all the dogs and they looked healthy and well socialized.
