Keith clamps on Jojo

I was digging some grass/weeds with Jojo out (and Kimo) out in the yard, when Pat comes out with Keith.

The usual commotion followed with Jojo running around and Keith lunging at him on the leash.  But this time, Keith caught him.

Keith had him by the side of the neck and wouldn't let go.  I pulled up Jojo since that usually makes the dog release after a while but Keith wouldn't let go.  Pat was hitting Keith in the snout, but Keith wouldn't let go.  I tried putting the flexi-leash handle between Keith's teeth, but it wouldn't fit.

After struggling for probably three or four minutes, Keith finally let go.  I noticed Keith had this crazed look in his eyes, sort of reminiscent when Kimo eyes used to turn red when he transformed into wolf mode.

I held Keith for a little so he would calm down a bit, then Pat led him away.

Checking Jojo, thankfully no blood.  Though the side of his neck was wet with saliva.

Later I wiped off the area with an alcohol wipe and he seemed OK.  Well, maybe not OK, but back to his old self.
