AL can you explain why you think that. It must have been about 2006 I was walking in the countryside with my own dog and met a lady who had a young Springer Spaniel in a contraption with wheels where its back legs should have been. It was charging around no problem, running up to other dogs and interacting, sniffing here sniffing there, came up to me for a stroke and pat on the head. Its paralysed back legs were resting on a ledge above the wheels is how I remember it. The dog looked very happy, it looked a life worth living.
