In the Doghouse

Vintage charm on a stainless steel paperclip chain with a stainless steel lobster clasp. I could not find a maker's mark on this charm. It features a dog, maybe a bulldog or pit bull, guarding it's doghouse. This charm is kinetic! It has a small knob on the back of the doghouse that if you wiggle it makes it look like the dog is protecting it's house.
