Well - I guess you always need to be ready to fight back with a kick or a swat to advise that this is not acceptable behaviour. Since the little monster is so apt to use his front end, I'd always carry a dressage whip when leading him - shorter and more accurate than a lunge whip - and it STINGS when they get lashed with it and you can nail them from a few feet away as well
When he goes up, he gets a sting with the whip and a loud "NO!!!" and pretty soon in his evil little mind he should associate "playing with the humans" with getting stung and he might be a little more inclined to leave his front feet on the ground at all times around you guys
Its been a quiet morning so far. Any chance of seeing the matching black eyes for you and hubby?
I am so sorry (all kidding aside) that the little terror is using you both as punching bags. Good luck with getting his manners back in line once again
