My rising four year old did this today and I am worried. I can’t feel any swelling or heat, so I am wondering what might be the reason for that happeningI was cleaning my horses feet tonight and when I went to do her right front foot, she fell. I tried again a little while later, she acts like she doesnt want to pick it up and when she does, she falls to her knee...I checked her legs, nothing seems abnormal and no swolleness anywhere. No cuts or wounds anywhere. I cant figure it out, I dont know whats wrong. Has anyone ever had this happen before...?
