While I don't own German Sheperd dogs, I occasionally have 2 who visit me quite often..

When I tell Hexay to sit, she "speaks" ( maybe in German? ) so, then I say--EH! EH! EH!!!-- "come on Hexay, you know the drill"----"Sit !" We'll go through this for a few minutes, or a few more " woffs", then, she'll sit!!! She is a very vocal dog most of the time anyway, for an Older German Sheperd~~

Kasha ( the black one) is well trained, she will sit and offer to shake your hand, but, she wants to be Grammas little Baby (Senior Dog), and keeps coming back for another treat when she has been a very good girl!!! It's so hard not to spoil her, she is such a sweetheart!!

Both of these dogs are just ANGELS!!!!!
