Velo-Dog

The Velo-Dog was a pocket revolver originally created in France by Charles-François Galand in the late 19th century as a defense for cyclists against dog attacks. The name is a portmanteau of "velocipede" and "dog".

Surviving examples vary considerably in appearance, but all have certain features in common. All have short barrels and fired the 5.75 mm (.22 calibre) Velo-dog cartridge. The hammer is shrouded to avoid its snagging on clothing, so the weapon is double action only. Another unusual feature on many guns is the lack of a trigger guard, and a trigger that folds into the body of the weapon when not in use.
