Perhaps it's just me , but every grey I've ever had has had some very strong aggression issues. Not so much my stags, but my greys for sure.
Here's the results of grey jumping my stag over the summer. Arliss, the stag got his ass whipped . However, Tut actually came away from it worse for the wear . During the scuffle ,he cracked his head against a wood fence post and got a 1/4" piece of wood lodged in his eye. Amazingly, we were able to save his eye . Everyone knows one eyed fast dogs will just run in circles.
