Uh, no, the source states that they were mostly Doberman Pinschers; what are your qualifications again? Do you claim to be a military k9 trainer?
Damn right they were Dobes.
They were the [in]famous “Devil Dogs” whose ranks later included GSDs and other working breeds.
Famous show kennels [such as the seminal Arthal kennels] donated their prize dogs for the war effort.
Most of the owners got their dogs back...when they survived.
Some let the handlers keep the dogs they’d grown to love.
[just think LEL, somebody, somewhere is paying beau coup Benjamins to this guy]
