Wolf collar
A wolf collar (also known as Italian: 'roccale' or vreccale, Spanish: carlancas) is a type of dog collar designed to protect livestock guardian dogs from attack by wolves. Wolf collars are fitted with elongated spikes to stop wolves from attacking dogs on the neck. Such collars are used by shepherds in many countries including Italy, Spain and Turkey.[1][2][dead link]
Use
A wolf collar is normally made out of metals such as iron. The length of the spikes can be quite long, but styles differ in different places.[1] The dogs that normally wore the collars were ones used to protect livestock from attack by wolves. The purpose of the collar is to protect the dog wearing it when it has to fight the wolves. The spikes provide protection and can also be used as a weapon. There are some tales that suggest that dogs were only given them after they had killed their first wolf; however, these are normally considered to be inaccurate.[1]
