answered question 9/29/2009 Are My American Bulldogs Black Spots All Over Him Normal . Someone Asked Me What Was Wrong With His Nose And If He Was Ever Abused. No He Wasn't. He Has Black Spots All Over His Skin,any Ideas? I'm an American Bulldog breeder and yes, it is normal for your AB to have black spots (almost like a Dalmatian) on his skin. It's not in the coat, it's actually pigment on their skin.
