Lad if it would help I'll contribute towards a reward for a return of the dog, pm me
This in a nutshell and something I've thought about for a while. Both me and the wife are massive animal lovers and have been following your story all the way.
As horrible and shit as it sounds after 6 weeks I'd imagine somebody has this dog and is treating it like their own. The only way of possibly getting the little furball back is this person being offered something financially that they can't turn down. Previous experience of a missing Dalmatian of ours.
Give them the money then bide your time. I'm sure @aguero93:20 will reward them with fire and bricks one day.
We would happily chip in too.
