I adopted my dog from a blacksmith. As soon as we got home, he made a bolt for the door.

Behind the Groan

One Very Handy Dog

“Make a bolt for the door” normally means to run suddenly toward an exit. A blacksmith supplies the literal meaning because making a metal bolt is part of that craft, and a door is exactly where the finished hardware might belong. Tell the adoption detail warmly, as though the dog's background is merely incidental. Pause after “got home” before revealing what he made. The animal behavior remains believable for just long enough that the hardware interpretation can arrive as the second picture.
