A collar for use in training animals, such as a prong collar, is provided that includes an attachment ring affixed to one end of a pull chain and a clasp at least indirectly attached to an opposite end of the pull chain. The collar may also include a neck portion having a pair of joining links affixed at opposite ends of the neck portion. The pull chain may be threaded through apertures in the joining links to form a closed loop with the neck portion. The attachment ring and the clasp may be dimensioned larger than the apertures to prevent the pull chain from disconnecting with the neck portion, thereby maintaining the closed loop. Once placed over the head of the pet, the collar may be secured with the proper fit by connecting the clasp to the attachment ring.
