I sold my horse two years ago to a wonderful family that took good care of her and then I moved my horse to a new home when I bought her back just about a month ago..She was on a Grass hay that they supplied that I think had like Wheat in it or something that looks like stickers or thorns, I will link a image.. And now she's got two big sores in her mouth on either side of her lower lip that seem to get the thorns wedged up in her lips in the sores and I have to pick them out!!! OUCH! Is this why she could be drooling so much lately?? I was able to rinse her mouth with a hose a few times..I just moved her finally to a new home on a grassy field with alfalfa now as food so no more thorns but im wondering if I should stay concerned about her email@example.com is my e mail should you want to contact me with some advice directly. I attached a image of the thorn like thingys that were getting wedged in her lip. Im scared she's got more stuck or lodged in her mouth that I can't see!
