My family have always "cherished" dobermans. I had one when I was about two, my dad had three before that, my aunt has had three, and the whole family always had doberman. We are getting another one in the spring, but when it comes to the price, they are quite a lot! If you groom them and they are in good health, they can sometimes come up to 1000. If they are in good health, and look good, they can be a lot. Most people want their ears pricked and stubbed tails as well.
Good Luck! (And if you are selling, we will take it! :) )
