It's rare because the Colby family doesn't deal with the public. they get phone calls everyday from people trying to get a dog from them. they are all about keeping the blood pure, and basically breed to preserve their strain. they usually only deal with freinds and family. Being as they no longer game test their stock (for obvious reasons), the dogs will differ compared to the older strains but are still nice representations of the APBT
. If one were to have the opportunity to get their hands on a pure Colby....I would say to definately go for it...regardless of what price they wanted.
