I beleive a lot of our red/white basenjis do have black hair on their tails, I am told it indicates the possibility of producing tri colored offspring if bred properly. Commonly referred to as 'tri-factoring'
Yes, that is correct, breeding to a Tri colored or another color with the Tri Factor and you can get Tris.
