Groucho

Groucho is best known as the stage name of comedian Julius Henry Marx, one of the Marx Brothers, though its origin as a stage name likely relates to the Yiddish gruch meaning grouch or sulky person.

Groucho is the name for a dog who has opinions — and isn't shy about sharing them. Maybe they grumble a little when disturbed from a nap, or shoot withering looks at other dogs at the park. But beneath all that theatrical bluster is an enormous heart. Groucho pets are usually the most hilarious members of the household.
