Hi, I looking at a 17 yr old appaloosa mare that is at a rescue. I was told that this mare is in good shape and loves to hit the trails. I would like to do a little distance riding witha a friend of mine and her arab. Does anyone have any tips for conditioning older horses? She doesnt require any special feeds or meds. She gets along well with other horses and only spooks at cameras(i have no idea why...). Does anyone else have an older horse that does these rides? I dont think i will be doing anything more than about 15 miles, and will only do it a few times this year.
