Comic-strip Beagle Snoopy made his first appearance in newspapers in 1950, and the rest is history. The Beagle was America’s No. 1 dog from 1953 to 1959.

Curious and comedic, Beagles often follow their noses, which can lead to mischief. President Lyndon B. Johnson’s Beagles, Him and Her, appeared on the cover of Life magazine.
