Hi..I just bought a 9 year old mare that has had minimal ground handling/riding for the past 2 years. The other day I haltered her and led her to the fence, where, after eating some tasty treats, she decided she was done, turned around and headed off. I still had the lead rope and as I was kinda flung to the end of it, she started trotting away. I had to drop the lead, but went after her and she stood to let me come up. I am bringing her to my boarding barn tomorrow and will have her take some lessons in ground handling, should I get a rope halter for more control?
