Wrote Charlie a long email here while back expressing interest in a puppy. Either he doesn't like me, or he is not interested in selling puppies anymore. I believe that puppy page of his is several years old. But, if he is infact still in business, he'd be a good one to contact.
Maybe you should pick up the phone and call him. Some people don't like doing business over emails. I'm one of them. I've been a oilfield salesman for 25 years and hate email. Some of my young customers ( that I see weekly) started texting and emailing orders in a few years ago. I'm never too busy to respond to any type of order but I'm not holding a commodity that's all that scarse right now. Bird dog pups in Texas are easy to sell these days. I would only do business with people who are easy to deal with and do business on my terms.
When I was growing up I couldn't have imagined paying for a pup. In the west Texas Sandhills if someone had a good dog and another man had a good bitch they bred them and all of your friends got a pup.
I drove to South Dakota last year and paid money that I thought was crazy for a pup I wanted. If I hadn't wanted her someone else would have gladly taken her. It's just the way it is these days.
