There HAVE been blue pit dogs. I have seen one's ped before. I bet someone more experienced here could link it. Blue is just a dilution of black. It can occur. That said, 99% of the time, if the dog is blue, it's not a real APBT. Razor's Edge is THE American Bully. The start of the American Bully. It doesn't get any "American Bullier" than Razor's Edge.
