I really liked that link aswell. What do you mean weight off once you were holding it? Like we're they trying to lean on you or the leg you were holding or?
Well Ive picked feet from a good amount of horses of all ages and breeds, going back to when I was at my first trainer in feb, and it was her and a couple other people who told me that you cant expect every horse to completely take all weight off their leg thats lifted up.
For instance, some will start to lift just as they know you are wanting that foot lifted - my mare does this some times, which is great! Sometimes I bend down and she knows and she will lift her foot off the ground. If she does this, I will always say thank you to her because she is taking the initiative to make things easier for me.
But I just remember that of all the horses that ive cleaned their feet from, maybe 1 or 2 lifted their feet and actually held it up on their own so that if you were to let go, their leg would still be in the same spot where you had it when you were holding it.
Fortunately, my mare does this sometimes. Some days she is great where she will use her muscle to hold it up for me on her own. When Im done and slowly let go, her leg is still up in the air, then comes down slowly because she was using her muscle to hold it up for me. Again, if she does this, I always praise her for it.
But then other days, she will not want to hold it up at all (Which is fine), cant expect her to do this all the time. Just like some days she will be in a worse mood than others so she may not be as crazy to be brushed and have her hoofs picked. So she will put weight into that leg.
Like I said, I will try my best to hold and hold and not let go but if she puts too much weight into it, I need to let go becuse its not worth having her knee crash down onto the ground again and risk injury. I got lucky the first time this happened and very fortunate she was ok, no injury, no soreness, no bruising. But when she tries to put her weight onto that leg in hoping of being set free, if its too much weight, I will let go of the leg so she can put it back on the ground, then I take the palm of my hand and wallop her really hard on her belly. That gets her immediate attention every single time.
I learned this from my very first trainer (before I had my mare), who her horses would occasionally try this on her and she would wallop her so hard that the horse gets startled because they were caught off guard. But she only had to do it once because she sent the message loud and clear.
