Hi Ashley
If you send me full details of your Dobermann bitch, good points, bad points etc (IF you are in the UK as it has a double "n" in this country) along with all her health test results and your facilities for rearing pups (and running them on if they don't sell or taking them back at any time during their lives if their owners have problems) I will see if I can help point you in the direction of a suitable stud dog
Full of the helpful Christmas Spirit (or will be shortly)
Christine
