The Brotherhood of Railway Mail Clerks was organized in 1886 to fight for better wages and safer working conditions. #NationalDogDay 🚇

Soon, I was adopted as mascot of the Railway Mail Service. Clerks gave me tags to track my travels. #NationalDogDay

In 1894, it was reported that my tags "jingle like the bells on a junk wagon" when I jogged. #NationalDogDay

The Railway Mail Service had its last ride in 1977: s.si.edu/1Jmbp3z Right here in DC! #NationalDogDay
