I never thought of that. I did that once with a litter of Doberman puppies. I got a call from a guy who told me he wanted an puppy with a lot of spunk and then what he wanted to train him to do. Then he asked me how much they were and I replied $1000. (Going price at the time decades ago was $125). He replied that was a lot of money and I said they were high quality. He then mumbled something and hung up.The sellers wife probably told him he has to "sell that old jeep!" So this was his solution. I like his thinking.
