Any advice for catching a horse that's hard to catch?
Walk toward their shoulders and not fron the front or behind. If you come from the front or back your horse will think that you are chasing them. Also, hide the halter behind you so that your horse thinks that you are not going to catch him/her. Hope this helps this was just what I learned from past experiences!
How long should you ride for before getting a horse
You should lease a horse first. This will give a feeling of all the work that goes into owning a horse. This will also give you the chance to spend time with the horse, practice, but you are only spending money on the horse part, not the vet, the ferrier, etc.
