Well she lives there. He doesn't. He broke out of the caravan when unexpected fireworks went off and took off through the farmers fields.
He is a very desirable breed for that area 
Tonight they are just going to wait up and then go and shout for him once all the partying has stopped. According to my mum they are on 'some kind of hippy or gypsy site' and everyone is still up partying.
But for tomorrow I need advise on who to contact (dog warden, one vets, police, microchip company and local pub owner already covered - pub owner has contacted local farmers)
They are in Matlock, Derbyshire Dales. I need contact details for any vets (apart from Peak Vets - we've contacted those), petshops, rescues, kennels etc. in the area and any other ideas that might help.
I am in charge of admin because I am the only person with PC access and I've never even heard of Matlock before today.
Apparently from now, if their dogs cannot come to me when they go away (the missing dog has a penchant for eating houses so DH says no) then I am to move into their house with their dogs, they are never going away with them again.
