starting to breed black wolfs advice needed

so im redoing my den to acompany black wolfs,ineed to see other black wolfs so i can decided on the future pups, trying to make this a markless pack justsolid black with any eye coloring, highly pefer blue eyes,and as soon as ican im retiring my alpha and his queen, they are not going to have any more pups, iwant to focus on black wolfs only.

My featured wolf/stud is Marengo with black marks and blue eyes if you want to look at him for ideas. I liked the idea of solid black, but then I saw Marengo and fell in love since it shows black markings
