The breed was even used in anti-German propaganda for children, where the Kaiser is depicted as a “rabid hound.”
The events are meant to be more fun than anything since obviously the breed was not bred for racing. The Wienerschnitzel Weiner Nationals is held every December in San Diego, California.
