The barn I am at now, my horse shares a stall, but it is their stall. He shares an attached limestone paddock with a buddy, but it is theirs, not rotated with other horses when they are on turnout. They get along, and they share if they need to, but most of the time they rotate themselves when one needs to take a nap. The board rates are reasonable compared to the area, so it’s not an issue for me. Not all the stalls are set up this way, but the price is the same. The BO works to pair horses with a buddy they get along with.
I wouldn’t expect anyone running a hand over, but they do put eyes on the horses. One reason I really like then barn I’m at, is that there are no barn hours. She actually has the approach the more variety of hours someone is there, the more eyes there are on the barn and horses if something is amiss.
I would not want the teens riding, unless I gave permission for my horse to be used for lessons, which if that was the case, I would expect a discount, instead of paying for training. The exception is if it is a qualified working student, it is not uncommon for the trainer to have their assistant work the horse, and if qualified, not a big deal for me.
I get it about feeling like a high maintenance boarder, but I don’t feel Iike I am, I just ask for some very basic things which to me are common sense. The barn I am now is the happiest I have ever been as a boarder. I am fiercely independent, and don’t do well at a barn where I am expected to be in a structured training program, or treated differently if I am not, but I like having access to a quality trainer. I also recently took my horse to a dressage lesson with a trainer I highly respect, only to come back to the barn to be told that we are not allowed to take our horses to outside trainers for lessons. I was a bit taken aback, I had never agreed to this or signed a boarding contract stating anything like that, and I never would have agreed to it. She was very kind about it, apologizing because she realized she had never really told me that when I came, but because she’s so small, it takes away from her income. The BO is a good trainer, an upper level eventer, but I do much better with a true dressage trainer. I want to earn my bronze, so it’s important to me. I will have to figure that out in the future, because I like I said, I am so happy otherwise at this barn. and I do lesson with the BO too for jumping.
So, in the end, you need to decide what is or isn’t a deal breaker for you, safety and care being of priority.
