One of my horses had some front toes bruising last trim (not bad, but noticeable). While trimming today the farrier said it didn't go away, but got slightly worth. She never had bruising in past, but we never had such an unusual winter either (warm, muddy, rainy, and with quite a bit of frozen -> mud -> frozen ground -> mud). My guy thinks it's because of rain and mud (so much softer hoofs, which is a case indeed), and them running a lot around the property so she can hit the hoofs while sliding in all that mud. He also said that he definitely noticed it in other people horses too, so she's not alone.
So the plan is to wait over couple trims (Spring is coming so hopefully everything will dry up), but if no improvement/getting worse I'll have to seriously look into shoeing the front (which my farrier is not very happy about either, because he's all for going barefoot unless absolutely needed).
So my question: is it something normal? What could be the reasons for the bruising (besides the weather)? Can I improve/prevent it in some way? Any other info/experience/ideas?
BTW, farrier said my paint's hoofs are OK (I believe she also had a little bit of bruising last trim, although I don't remember for sure). But qh is generally more heavy on front and more clumsy. Also we have mats around the hay rack to keep them from standing in mud, which really works.
