Aubrey Lipsey line dogs for La

The dominant colors are buckskin, black, leopard, and yellow. My profile pic is a leopard pup off our last litter off my yellow gyp and my brothers blue leopard male. I bred my gyp again to him when she had her last cycle and she didn't take. Not sure why. My brothers dog has some age on him and I'm hoping he hasn't gone bad. So I am looking for another Lipsey female to breed to one of his pups to keep the bloodline going. They are jam up bay dogs on hogs and cows. Very gritty dogs. My Uncle Aubrey had people from miles around to get these dogs of his and even had a guy come over from Italy and bought one. Like I said before, they are legendary and my brother and I are just trying to get the bloodline build back up.
