Thanks for all the replies folks they've all been helpful. It shows this forum at it's best.
We've come to a decision and we're not going to go ahead with this. We discussed it at length last night and we decided we can't take this dog or any other for that matter on, certainly at this present time.
I thought we would love another dog ( which we do) but after taking a hard look at our lifestyle and the extra costs, we both feel it's not an option at this minute. It's a very hard decision to make but I have to do what's best and not let my heart rule my head. I feel Harry is the most lucky dog in the world, he has the best of everything and we don't want to spoil that.
I really hope the guy succeeds in re homing his dog, don't know if anyone on here is interested. PM for details, but he's a 5 month, chocolate Worker, tail leaglly docked, not KC.
Again thanks for all the help and advice in this matter.
