Emaggie - my friend has a JR (Lulu) and when she was a pup (7 years ago) she was full of beans and would run around and play with my JR. However, one day for no apparent reason, when my friend got to the park Lulu ran hell for leather to the other end of the park and sat outside the gate shivering. She had never done that before and was clearly spooked - but by what? She has never recovered and whilst Lulu is very happy to trot along the roads or woods with my friend, as soon as she gets near the gates of the park Lulu she becomes quite nervous and clearly on edge. Never discovered what it was that spooked her, doubt we ever will.
