I had a coach tell me once that my horse's mane was flipping to one side at the wrong "spot" because he was artificially carrying himself and therefore the neck muscles were pushing the main to the wrong side.
(In years past, I have heard it described as breaking at the fourth vertebrae.)
Is this really a "thing"? Neck muscles dictating mane position?
(I'm just casually curious! Not really sure if he was exaggerating to get his point across or if this is really a "thing".)
I've been told that the mane falls to the horse's hollow side. it does this because the horse's muscles are less developed there. I have seen horses' manes "change sides" -- at least partly, as their muscling evens up and they become supple both ways. I suppose, in a perfect world, you'd have a "half & half" mane.
As a horse flexes right or left, when done correctly, one can see the nuchal ligament "pop" the crest of the neck back & forth. it's what joiedevie99 was talking about.
I have heard this & looked extensively on the net for answers. I find it easy to believe, being an equine massage therapist & thus aware of the muscular development of horses & the equal muscles mass causing hair folicles to fall in such a way. However I posted it on another message board & the over ruling response was that it was a load of. HOWEVER when I started trimming all my horses myself, all their manes split exactly down the middle?? I think it will always be one of "those thing". Really interesting to hear other people's thoughts!
