White/dry patches and sensitive wither
My horse gets dry spots on either side of his wither, where there are white patches from past badly fitting saddles. They aren't painful to touch, occasionally he will twitch as though itchy, but rarely. He shows no pain response along his spine. These patches are also pressure points; if the saddle is too far forward and rests on them, he will buck. I've had him chiropractored, and the saddle fitted twice, and they still occur. (by occur I mean the pressure points if the saddle is too far forward) I'm wondering if the damage that caused the white patches and pressure points may have injured the sweat glands? I know the saddle is resting there as the hair is disturbed. Larger patches have recently come through, but I know the saddle fits and he doesn't have any muscle damage... I ahve been told white hairs can take a year too come through so it is possible these are as a result of his last saddle. (I have had him about 6 months)
Also, once or twice after long periods of hard work i've noticed the white patches raised about a centimetre or so. They weren't painful to poke but he did twitch his skin as if they were itchy or sensitive, but no pain response (for him ears back, trying to bite)
And one more thing in that area, his rug leaves disturbed hair on his wither. There are no actual rubs or marks or sores, but to touch he twitches compulsively and throws his head/tries to bite. Same as when I go to straighten the rug.
Could he just have very sesnsitive skin in his wither/wither pocket area? I can't figure out what is causing the dry patches, which is really frustrating, as I want him to be as comfortable as possible.
