A collar is a band, circlet, or shackle that fits around the neck. The charge is most often found around the neck of a beast; such a beast may be blazoned “collared” or “gorged”, and the collar may trail a chain.
There are instances, however, of a collar used as an independent charge: e.g., the “pair of hames” or horse collar. It was used in the badge of Marcam or Markham, c.1520 [Walden 265; Parker 302]. See also shackle.
