Anheuser-Busch has no business using the ghost of Spuds MacKenzie to sell Bud Light because that doggy don't bark for the beer giant anymore ... according to a new lawsuit.
Spuds Ventures says it currently owns the rights to the beer-drinking party dog from the late '80s, and Anheuser-Busch completely screwed them by bringing Spuds back for a Super Bowl 51 ad without getting permission.
According to the docs ... A-B abandoned its Spuds MacKenzie campaign more than 20 years ago amid controversy the dog made beer kid-friendly. In 2013 Spuds Ventures swooped in to take ownership of Spuds.
