You are right though LightsOut, Razor's Edge is a bloodline just like Gator, only difference is that Gator is pure
APBT blood and RE is pits mixed with other dogs. (i.e. english bull dog, cane corso) Athough just because a dog is an RE does not mean it is blue, RE is a line started from many stock dogs unlike Gator which was started from a dog named Gator(Could be wrong bout the Gator so someone correct me). Showing us pictures of dogs that meet the standard of a pure
APBT does not mean they are pure
APBT, you MUST look at the pedigree of a dog to be SURE it is 100% anything, and that goes for any kind of dog.
As for the Gotti line, its the same as RE, just went to a different extreme with the breedings.
