It's so fun to be around such dogs! ^^ Do you herd with him? 
I haven't tried it, kind of scared he would bite the sheep! Lol. But maybe one day I'll bring him for fun to a herding instinct test
It's only natural that they bite the first couple of times - but by the time they'll understand the principle of moving the sheep using their characteristic 'eye'
