We do not have Cactus Cash in any of our current dogs. We did breed to one of his sons once, but we have nothing from that br
eeding. You also have to remember that the breed did not start with him. He goes back to many other popular sires such as Cryptonite and Windwalker befoer him. They can be found through many other channels than Cactus Cash.
On the other hand, we have used Lex Luthor 4 times over the years including having an exceptional current son of his that is only 9 months old (See link below). Some uninformed people like to speak of health issues in his line, but we have had several that have lived into their teens.
Based on current genetics, we are big believers in the UC Davis VGL and Betterbred genetic diversity testing. It will tell you more about the actual genetic diversity (internal inbreeding and similarity to the rest of the breed) of your dog or a mating pair than any pedigree ever will. https://photos.app.goo.gl/QjURvWkEXFo1d5qz6
