Hi, I got my horse last June, she had the most strange pigmentation on her lips, they were white, like someone had put white lipstick on her! They were quite swollen, but went down in the winter. So i'm pretty sure that its an allergy to something she is grazing. I've seen blistering caused by buttercups but this is actual swelling of the muzzle, no blistering and changes her skin pigmentation! Her lips are not white (yet) they are slightly swollen and there is some slight colour change, but I think bringing her off the grass and giving her hay is helping. Seriously wierd. Anyone ever experienced such a reaction?? Or is it just my strange horsey!! I've zoomed in on a pic of her you can just make out the whiteness on her lips!
Would love to hear if anyone has seen anything similar!!
