Never used hobbles on a Mini, do not own a set so can't say if it would work.
The only time we did use hobbles with the Arabs we had those shoe things as well, that go over the feet....we had a few mares come in with hind shoes on, and, well, could not take the shoes off ourselves, couldn't get a farrier and could not afford to turn away the stud fee, so we put the boots on and hobbled.
The stallion got a foreleg caught in the hobbles, once we had sorted that out the mare, quite justifiably , took a pot shot at me, her hoof cam nowhere near but she nearly knocked me cold with the boot thing as it flew off and connected with my head.
After that we settled for a pole twitch, correctly and gently applied, and had no more problems.
I will occasionally use a twitch on a maiden mare, but really only to get her to quiet down, and even then the majority are just fine.
Carlos is a very canny lad, and he is a bit of a mouse with the mares, very respectful when loose with them, an absolute BULLY when hand breeding, I will do it, and I do make him, but he doesn't seem to get any quieter, I have to say, and I take no back talk from my horses, you know
I agree with the possible damage, one of the main reasons that Rabbit is as highly strung as he is , is purely that he was badly kicked as a two year old, and had testicles the size of small melons ...I was SO lucky, also very lucky to have a river and a child willing to get up before school and back him into the river and leave him there for half an hour. I did the same at lunch and in the evening, but we were still really lucky.
It affected him all his life, he was a
mess all through the breeding season, could not be turned out at all, not even in a round pen, and stall walked constantly.
He is 31 this year and he still walks incessantly, but, for the past fifteen years I have at least been able to turn him out in a paddock and, although he still cannot ever go in with other horse, I have put his round pen in the mares field, and he can interact with them in a controlled manner.
Carlos is the complete opposite,
He is a shy boy, very nervous and he is content to just graze around the girls until they indicate (I will find him with his head soaking some morning, sorry to be so gross!) that they are ready to breed, thus they call the shots and at all other times Carlos is too far away to get kicked!!
I
still prefer hand breeding!
With Rabbit it is soooo easy, he has always been such a gentleman and I am so sorry he never got to know the joy of standing under an oak tree with one of his foals, just chilling out.
If I had been more careful in his first year breeding he might have had that joy.
