What is the difference between a halter and a bridle and can you use a halter like a bridle on a horse can you put a bit on a halter?

Well, bridles are used for when you are riding. Most have bits, although there is one type called a bosal that uses no bit. Bridles also have reins to hold while riding. You can use a halter like a bridle on a horse, just using the halter and a lead rope, but you cannot attach a bit so it can be very UNSAFE. When riding, you should always use a bridle. Halters are made to lead horses from place to place.
