Your nogerian is not a CB,lol
I would say rehome the weeksii, nigerian is really up to you but i like how nigerian lap look like, plus they always out in the open.
He loves that weeksii
Id say the ansorgii or koliba or even croc....hiders suck, agression sucks almosy as much hiders. Would you be replacing ? If so can replace the endli with one thats not aggressive
