Wolf bounties were regularly paid in Italy during the 12th and 13th centuries and as recently as the 1950s. Gian Galeazzo Visconti himself offered ten Imperial marks for every wolf killed. 600 wolves are recorded to have been bountied between the 14th and 19th centuries. Presentation of the killed wolf to the authorities was obligatory. The authorities had to give an accurate testimony with a description of the presented animal (gender, weight, measurements, color, estimated age, etc.) and the symptomatic ascertainment of any rabies infection. The wolf's paw was then amputated and/or its ears were sealed in wax in order to avoid the spoils being represented elsewhere. Only one case of fraud occurred, in 1834, which was punished by arrest. Italian wolf hunters lacked the organisation or determination of their French counterparts, having not formed any special hunting teams. Wolves were exterminated from the Alps in the 19th century, though they were never fully exterminated in the peninsula.
