We had a briard in our family for many years. This post brought back many happy memories.
I remember standing in the garden, and gently pulling on a shredded nappie (diaper), the other end was still mostly inside of Remus.
The smell of this dirty nappie, a stolen meal, had wrapped itself around the insides of our 'son' and was about three feet long before the whole thing eventually came free.
This took some time and I remember smiling and politely waving to passing neighbours as if it was quite a nomal occupation. He did not appear to suffer any lasting injury but did not repeat the experience, I am glad to say.
