Fido’s Latin Origin
The name Fido is a fairly common dog name. In fact, it’s been used so much that it’s almost a cliché. But most dog owners are unaware that the name Fido is derived from the Latin word fidus, which means to trust or confide in. This might explain why US President Abraham Lincoln named all five of his dogs Fido before he became president. It’s difficult to find trustworthy people in politics, but luckily he had his dogs who were blindly faithful.
