I do not pretend to breed Dobermanns with perfect heads, but I remain attached to its type as described in the standard.
Following the article: THE HEAD BETWEEN DUALISM AND PARALLELISM Drs Angelo Magnifico and Massimo Massa; I produced these drawings of the typical head as well as some examples of defects (not exhaustive) with the help of Dr. Angelo Magnifico that I thank.
This is only to guide the various enthusiasts on what the real guy at the head of the Dobermann.
