well had to vaccume and he tried to kill it again. my 5 year old daughter thinks he is protecting his family from the evil cleaning machine. he sees it and then he is almost on top of it. barking and growling and biting the darn thing. the dog whisper sounds like a good idea. here it comes on at 10.30 everyday. i watch it all the time. it has really helped when working with our bernese. ( he used to shake his head all the time. guess i just have dogs with weird ticks.)
