The .44 Bull Dog was an American centerfire revolver cartridge produced from 1880s until 1930s. No known firearm was chambered exclusively for the .44 Bull Dog cartridge: It was a shorter and less powerful option for use in revolvers chambered for the .44 Webley cartridge (American name of the British .442 Webley revolver round). The .44 Bull Dog cartridge was manufactured only in the USA, probably for those bothered by the sharp recoil of the more powerful .44 Webley round in such small guns, or who were particularly cost conscious.*
