LOL Wish I could help but I have the opposite problem! I say "HERO DOWN" and he does a little bunny hop then dives on the ground like a pounce! but then he gets right back up! The more I work with him (every day 10-15 mins a day 2-3x a day) he is getting better.
Haha i bet that's fun to watch! Yeah I've worked on it for a long time and she hasn't rotten it, so i thought maybe i need some advice and a new way to try it
