Carpal canal syndrome, or carpal tunnel syndrome, is the most common entrapment neuropathy in humans and is caused by compression of the median nerve as it courses through the carpal canal. A similar condition has been reported in horses, however there have not been any reported cases of a dog showing lameness secondary to compression within the carpal canal. This report describes the case of a dog exhibiting lameness secondary to a lipoma within the carpal canal. Lameness improved after surgical removal of the mass. This case highlights the need to consider compression of the tendons and nerves in the carpal canal as a cause of forelimb lameness in dogs when pain is localised to the carpus.
