At DH Equestrian we have stability reins for your horse or pony. The Amazing Stability Reins The new and improved sliding elastic support reins connect to the D rings of your saddle. (extenders are available on the website if your saddles does not have D’s), The rein will come into play if your pony/horse puts its head down too far. (i.e. snatching to eat grass, running out, or bucking etc. The pull is then transferred to the elastic rein, stopping at the saddle. The stability rein acts like a second pair of hands with contact remaining always with the animal.
