The bear was at the Scala nightclub in the town of Guipry-Messac, between Redon and Rennes on Saturday as part of a circus night.
But Facebook and the Twittersphere were left shocked.
“Scandalous”, “pitiful”, “shameful” were just some of the adjectives used to describe the photos that were shared of the bear in the club.
Many blasted the nightclub for organising the event and alerted animal rights charities.
Below the pictures on Facebook a comment read: "Shameful. We need to boycott this nightclub. Animals are not toys."
Another read: "Welcome to the middle ages".
And another: "Wild animals have got no place in a f**king nightclub."
There were hundreds of other similarly invective comments directed towards the nightclub owners.
A petition to end the practice quickly garnered over 2,000 signatures.
The Scala nightclub has not responded to the outrage.
