thats true i never could understand why volka does that he just comes and lean against me with all his weight. and yes brushing was a problem at first now  its ok no problem...cleaning his ears was also a bit of a problem not anymore. here is a story but it was not volka's fault..i was training him with a long leash and i threw a ball for him to fetch he just rushed to the ball, the leash was accidentally wrapped around my legs ..he just snapped me both legs out in the air and dragged me ,,i landed on my back and on my wrist..i had to put a cast on my wrist for a month..was a hairline fracture not serious but all the ligaments damaged.... that was when he was 8 months ..still hurts me up till now. as far as biting i got my share when he was resource guarding his bone but after that he was very sorry he acted on a reflex. 

but with lots of work he is now very very stable and never snaps or acts on a reflex with me.
