Like most training tools, head halters can be used to inflict pain and punishment. When used incorrectly, some head halters can inflict pain or injury even if the handler doesn’t intend it. Some head halters, such as those where the lead attaches below the snout, are designed to apply more pressure to the bridge of the nose. If these halters are used incorrectly or with punitive training they may well be inhumane. Head halters that attach behind the head are generally humane even when used by an amateur.
