I have found a better way to brace your baby. Walmart sells cheap spray bottles for a whopping $.97 and you can mix up a little linamint and water to spray on your horse's back and loin. You can also add a smidge of witch hazel if you're a mind to.
Seems to me better to spray a mist onto her back and loin and lightly massage in, not to totally dry (you'd be there all day) but to make sure it's getting down to the skin. Even spray on the cannons and tendons but I like full strength for down there and then fairly vigorous massaging.
Of course, the upshot is the minute you turn your lambchop loose, she's gonna lie down and roll, getting nice and icky but happy as a clam. That's what's important now, isn't it??
