I always brush my horses manes before putting on the collar. I lay the mane flat, with my hand, under the collar to ensure it doesn’t rub the wrong way. I have tried “greasing” it up with petroleum jelly. I have tried plain leather collars, felt pads, vinyl pads, and currently permasoft pads. All to no avail. I cannot get my manes in the collared area to grow out. Even on our previous Belgian team, the hair was always short there. Now, with our new team, it’s not only short and straggly, but one of the mares (with a thicker neck) actually gets apart of it rubbed completely bald. That being said, they don’t show any signs of soreness or tenderness on their collar areas. I have ensured proper collar fit and hame adjustment. Am I fighting for the impossible? Or am I doing something wrong?
