are you Vietnamese? They actually are bilingual lol...i started them with Vietnamese first then English. It goes to show that they do know their own individual names lol...sometimes i wonder if they did or not because when i call for one the others coming running except the one i am calling...lol...
they know other tricks too but being outside and the area i was in i didn't want to have to sit my butt on the ground so just stuck with sit since it was easiest to do from where i was sitting and holding treat and camera...
