This is at Karen's open house. She can quietly ask Hector to howl and he will, getting the others going. She'll let them all howl for 10 or 15 seconds, then quietly say, "ok, that's enough" and they'll stop. If she could teach children to mind like that, she'd be a millionaire! This video also features "our dog" Batdog as he howls. (This clip is 5.2 MB in size, 29 seconds long).
