WEll
im not all too good with canine anatomy
and i know the ears and head are a bit big
but
heres a nice headshape for you
i generally just draw a circle then the forehead and for the muzzle i sorta draw out, making a sort of seven shape. You never want to make the muzzle like, straight on the front. thats for sure

Although I'm not the one to really listen to, I hope I helped in some way xD
