BMC Ladner bloodline

I had a real good looking one for a while. Drove almost to Kansas from southeast texas to buy him. He did rral good and was a good long range hunter. I had wormed him and he was very healthy and then all of a sudden one day he just died. Still haven't figured it out. All my other dogs were fine. Just kinda makes me shy away from expensive dogs. All my other dogs have been free and you couldn't kill them if you wanted to. They eat chicken and fish bones everyday, play on heavy machinery, mix prescription medication with alcohol...
