Doberman Pinscher Adult Dog Wanted

Dear Sir / Madam I am searching for a brown and tan (liver) Doberman bitch (pup or rescue dog) to replace our 12 year old bitch, Keya, which we had to put down due to cancer in the front leg. Her companion, Otto, is 4 years old, lonely and needs another companion. Kindly advise whether you could assist in this regard. Thanking you in anticipation.
