I was doing some gardening near Whitsands Bay, East Cornwall which is a good site for para-gliders.
First time my pair have ever seen one (a para-glider) in the air and they were so panicked - yelping and trying to get close to me, but hindered by tethers. Luckily I sussed the problem in quick time: however, "dad's" reassurance was not good enough to settle them as the 'glider circled round so I put them in the car where they settled soon enough.
They are not fazed by buzzards, for example, or planes, but I wonder whether the huge slow para-glider triggered some sort of primal/innate fear of large raptors. (I've seen - TV/web - Golden Eagles take foxes and even larger mountain sheep.)
Anyone else experienced similar doggy distress ?
