removed in a manner similar to the bridle. Many halters have another short strap connecting the noseband and the throatlatch. The halter design made of rope also has the same basic sections, but usually is joined by knots instead of sewn into rings. Most designs have no metal parts, other than, in some cases, a metal ring under the jaw where the lead rope snaps, or, occasionally, a recessed hook attachment where the crownpiece can be connected. However, in many cases, a loop is formed in the left side of the crownpiece and the right side of the crownpiece simply is brought over the horse's head, through the loop and tied with a sheet bend. Leading In addition to the halter, usually a lead (lead line, lead rope) or leash is used to lead or tie the animal. The lead is attached to the halter most often at a point under the jaw, less often at the cheek, and rarely above the nose. On horses, a lighter version of a headcollar or headstall is also used to attach a fly veil of waxed cotton strands or light leather strips onto a browband. Some fly masks are also made in a similar pattern to a headcollar and are often fastened with velcro tabs. These masks may also have ear and nose protection added to them. On both horses and dogs, halters may be used to attach a muzzle. Safety and security issues For tying, it is disputed if a halter should be made strong enough not to break under stress, or if it should give way when tension reaches a certain point in order to prevent injury to the animal. Usually the issue is of minimal concern if a tied animal is attended and the lead rope is tied with a slip knot that can be quickly released if the animal panics. However, in cases where a non-slip knot is tied, or if a soft rope is drawn tight and the knot cannot be released, or if the animal is left unsupervised, an animal panicking and attempting to escape can be seriously injured. Those who argue that the risk of injury is more of a concern than the risk of escape recommend halter designs that incorporate breakaway elements, such as a leather crownpiece, breakaway buckles, or easily detachable lead rope. Those who believe that escape is the greater danger, either due
