@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.
Had you opened a new bag around the time this started? Sometimes they change ingredients or suppliers of ingredients, which is the way an allergen can sneak in....
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!

Read this comment from @morgansc within this post dated May 30, 2019, 7:49 AM. It answers your question. Ideally it is best to wait until age 24 months but no early than 18 months.

Then you are fine…. worst would be a Carrier... no worries....
That's why I chose Katie. After much research into breeders in my area I was very impressed with the bloodlines she produces, and happy with how she has bred to clear any possibility of Fanconi from her bloodline.
ALways good to wait longer to get a pup and know you chose the right breeder. :D
