Oh Anna! I hope you feel better soon, that looks just awful .
That must have been really frightening. It is so hard to know what to do when your own dogs get into a fight. You just automatically step in (even though it's not a good idea) and try to separate them, I've done it before, too. But you're right, when those instincts kick in, the last place you want to be is between them.
Poor Huney, is she ok? She probably ran under Bon's legs just to be closer to you, she's so attached to you. I know Bon is a big sweetie, but gosh, he is such a powerful dog. It could have been much worse.
Prayers for a quick recovery, and (((hugs))) to you , Huney, Roxey, and Bon. We love you guys!
