I think it's all a misunderstanding really. There are several titles that say things like 'Gavin Robertson, Jilly (Crufts Best in Show winner - CH Soletrader Peek a Boo) and friends are walking approx 130 miles from the NEC in Birmingham to Great Ormond Street Hospital in London to raise money for both GOSH, DogLost charities and The KC Charitable Trust.'
But at the same time they have made no secret of the fact that none of the dogs will be doing the whole distance, just Gavin and Amelia. I think JH has assumed they were and went off on a tangent, going as far as accusing Gavin of cheating!
