We have a cutting bred yearling filly my husband is starting to fool with - has he taught to load in a trailer, has saddled her with a pony saddle, snaffle bit, hobbles (she hates them!!) - standing tied, clipping and trimming her feet. What other kinds of things can he do this summer to get her ready for the trainer next spring? Also, does anyone have a good reference book or article on how to teach a yearling to lunge? Can't seem to find anything in the few horse books we have on hand. Thanks for your help.
