about my red nosed pitbull

Question
My quesion is do all purebred red nosed pitbulls have black roofs of their mouths? I was told my puppy is purebred and I was going to mate him when he gets old enough, but they said that he isnt full bred because the roof of his mouth is pink not black.. could you please answer this question for me because i can not find this answer anywhere.

thank you

Answer
That is a myth-both purebred and mixed bred pitbulls can have a pink or black mouth,it's just like having freckles some have a black mouth and some have a pink mouth

Either way is not a good indicator of a dog being pure or mixed,only papers can tell you that
