Doberman Pinscher

This is my dog from the late 1960's through the early 1970's.   She was AKC Certified and Police Training Certified and as typical with the bread, EXTREMELY intelligent.   She could operate completely via Hand signal (silent command), attack and patrol 2 acre property and be loving and sweet to the family members (110 % safe with the children) .   

Her fullname is not yet known, it is obviously Blackjax ______?    We called her "Jax".     I was a kid when this dog lived and am searching for her records.   I will update if i find more.  Her DOB is aprox.  She is NOT the same dog(s) as the other Blakjax's but may be related,  since 1 other is from same US State and same period (1960's-1970's).

The pictures are from 1969 - i think she was 1-2 years old.
