Gordy is picking up on the fact that we end "just for fun" tricks sessions with a bow. Either way though, with just for fun stuff, or with any obedience training we do, we use his release words at the end of the session. For Gordy, those words are "Free dog!!!!" and he can do whatever he wants to do. Though, sometimes he does stuff that he really isn't allowed to do, and we'll jokingly say "not that free!!"

Likewise, we don't use them until we are done with a session. After a down stay, for example, rather than releasing him like some trainers do, we go back to his left shoulder and will say "let's go!" or "Heel" and move to the next thing.
After we say "Free dog!!!!" we give him lots and lots of praise, and ear and tummy scratches, and no matter what we have just done, be it tricks, obedience, some of both, taking a walk, going on an outing, playing a game... absolutely anything and everything we do with Gordy, we always
always tell him "Thank you for being such a good boy" and mean it. I get it that he might not know what exactly the words "thank you" mean, but I 100% feel like when I say something like that that comes hand in hand with honest feeling behind it, that Gordy gets the sentiment. And maybe I'm wrong on that part too, but I tell him anyway. He works so hard for me, and if there's the slightest chance I can let him know I appreciate it with a few kind words, and some scratches behind the ear, call me crazy all you want, but I do it, and always will. Same way I kiss him on the cheek and say "Love you" or "Goodnight."
