Jay's beloved dog, Luger - 31 January 2007 

"We were all saddened to hear that one of Jay's beloved dogs, Luger, had to be put to sleep yesterday following an ongoing illness.  The ten year old German Shepherd suffered from Motor Neurone disease. He was always there to greet guests at the house and was a permanent fixture in the studio where Jay rehearsed and recorded. He will be sorely missed by everyone."

Back in November 2005 The Sun newspaper reported that Jay had considered flying back from a promotional tour in Australia to look after Luger, who had only recently fallen ill.
