Sorry to be so late on commenting here. There are several Facebook groups you may want to join. 2 are Basenji specific.

The third group is secret and you need to be Facebook friends with a member in order to join. Contact me if you are interested in joining - Basenji Cystine Bladder Stone Awareness.
@Rebel - Full blood workup including full Thyroid panel (full panel no just what the normal vet workup that is not a full thyroid panel)... as they say make sure that he is in good health. Also what are you feeding him? How much total are you feeding a day? Also with reducing food, add veggies to his food to fill his belly... green beans are good to use... I use Cauliflower and Broccoli... Note also that low normal is typically too low for Basenjis.

My Kembe had the freckles on her neck - more pronounced in summer months w/ the sun and also as she aged. I use to call her my little 🦒 giraffe. 😂
To give you an idea of the contrast between Basenjis and Border Collies, my BC once spit out a pill, I said "Blackie" in a disapproving tone, and he picked it up from the floor and swallowed it!
