This workshop will start with a presentation on the importance and benefits of international collaborations among groups campaigning against animal testing to strengthen the antivivisection movement globally. Camp Beagle has employed different strategies to forge collaborative working relationships with antivivisection campaigning groups from other countries to increase effectiveness. Then, the floor will be open to discuss how different groups can collaborate and join forces to create international pressure campaigns. This workshop is for anyone already involved in campaigning to end animal testing and for those interested in getting involved in antivivisection activities, and it aims to create a space where international collaborations can start to flourish.
