Please take some time to visit Special Needs Dobermans! This organization works very hard to help Dobermans in need of health care.
The Special Needs Doberman website states:

We are an organization of people with a common goal of helping senior and special needs Dobermans. That need may be financial or it may be only information and/or moral support for the owner of a Doberman with a serious illness or injury. We will also aid in rehoming and fostering senior Dobermans. These Dobermans may be shelter rescues or they may already be much loved companions with a special need. Financial aid may be through donations or through avenues such as online auctions. Every precaution will be taken to assure that the need is real.
