I have food/water out 24/7 so there is no "performance's" for that, however...
When I decide to treat my guys, they hear the packaging being disturbed to get the treats out, and come sit patiently in front of me, until their name is called.
One exception though...
Navi (newest arrival) stands up on her back legs, sorta dances, and has a serious problem taking/waiting her turn.
I think she was a single Dog at her previous residence.
