I hope you find the one that is still missing. You were lucky they only broke into the shed, they could have stolen your dogs as there is a gang stealing dogs to order and shipping them abroad. Some of the dogs, once abroad, are sold on street markets. Are you checking the rescue kennels vets and putting out posters for the missing dog?
What breeds or x-breeds are your dogs? Particularly the missing one? Perhaps you might consider signing the Stolen dog petition to get the authorites to take this type of theft more seriously than they currently do.
