I am curious what the dollar value is on retrievers if i were to sell/buy them. I'm a trainer and have worked for a top notch training facility but have not dealt with the values of the dogs themselves. What would a ball park value be for labs that have went through ob, ff, singles, doubles, gun training and are fully ready to hunt with excellent drive and excellent perfomance? Also what would the difference be for the same dog without papers? How much value does 3 handed casting add when selling a dog?
