We had decided to trail ride and leave the Shetland mare at home. That lasted about 10 min. She'd picked her way thro the fence and came running up the trail hollering her head off. Since traffic wasn't a concern she came with us on all the rides. She was the boss so leaving her at home didn't suit her one bit.
Well, I guess that is one choice, but I would never take a horse along, just because I had no safe facilities to leave it in.
Yes, I pony horses, to fit them up, or a pack horse, but i sure would not take a horse long each time I rode, just to feed that herd bound behavior
get a third animal
iF that is not viable, have a safe place where the one left behind, can learn separation is not the end, and that companion will return. This, is in my opinion, something every horse should learn, but you do need facilities, and not just hope a horse won`t jump a fence!
Most important, while you have no influence on that horse left behind, far as calling, ect, except to provide a safe facility, you do, and must insist that the horse you are working with, ignors that horse left behind
If you always drag that other companion along, you also do nothing, faR AS TEACHING THE HORSE YOU ARE RIDING, TO RIDE OUT ALONE, TRUSTING YOU, AND NOT ANOTHER HORSE FOR SECURITY
in other words, not having facilities safe to contain the animal left behind, and thus forced to take it along, is a compromise not in the best interest on anyone, rider included
Also, just letting an animal follow along loose, except maybe a dog, responsive to call is plain stupid, esp if you are just riding with those two animals.
The loose one can decide to bolt off, and since you have allowed those two to become `joined at the hip`, you are looking for a possible wreak.
Yes, we often turn our pack horse loose, once away from the staging area, but I am not riding alone, so there are at least two horses controlled by riders, so that pack horse is not likely to leave, and have a saddle horse anxious to follow it, should something really spook it.
We also leave that lead shank, tucked into the diamond hitch, so when other riders approach, we can easy take up that lead on the pack horse
Sorry, having an animal just tag along loose, unless it is a well trained dog, is just not a good practice. I also would not wish to NEED, to lead a horse every time I ride somewhere, and reserve that for when I have a purpose in doing so
Thus, if the expense of a third animal is too great, invest money to build a safe stall or pen, to keep that mini in when you ride
