It is terrifying. Dog thefts are nowhere near as prevalent in Germany as they are in the UK, people here think I am totally freaky about it, but I am always very careful. For instance, if our dogs are out in the garden (with the front door open), we always have a padlock on the front gate. And lots of people here who do gundog training leave their dogs in the car while they are training with their second dog - they always have a locking system so the dog gets fresh air but cannot (theoretically) be stolen, but I still wont do it.
