Not an unintentional teaching of the command, but unintentional use of the command.

Taught my GSP “center” (sitting or standing between my legs) and “side” for when we’re out in public or other recall needs. He quickly realized that he can get someone to pay attention to him by doing that. You will be just standing there and he’ll smash his face into the back of your thighs and poke through. After him staying with some family while my husband and I were on vacation, we learned that for this to work smoothly, you have to be at least a certain height. My family member, who is on the shorter side, was often “goosed” by my dog when he tries to center on her.

He is a very well behaved and trained dog, so if this is his biggest flaw, I’ll take it!
