CLARIFICATION:
The head is very broad and short. The muzzle shorter than the length of skull.

The ideal proportion of muzzle to skull is four to five (see above).

The muzzle full but not heavy; yet broad enough to hold a full set of large, strong teeth. Heads may go to extremes and be too heavily boned appearing coarse and too fine appearing "snipey".

Please note the Standard does not call for a foxy head-only for a foxy expression (smart, alert, cunning expression), which is lost if the head is coarse or overdone.
