i just saw this post from ageeessss ago
I have a DVD of Jan Fennell's which demonstrates this exact behaviour in a GSD & demonstrates what to do about it. Speak with me off line & I'll get you a copy. I get a bit lost with the PM system on this forum, so go to the "contact us" page of my web site & drop me a line.
A friend at club adopted a GSD rescue with this exact problem. I gave them a copy & they fixed the little girl in no time flat.
It's fixable, but will require patience & dedication.
and although many issues have improved id still love to watch it!
i know you said contact you off line i dont know your details so ermm is this ok
contact contact contact!!
