My lovley mare is very lame on the same leg she did her ddft about 4 years ago. Vet on way but cant find heat or swelling anywhere. She is 22 and my happy hack but am worried sick about her. Yesterday a neighbour was shooting so i wonder if she has damaged something as she hates gunshot. on box rest as we speak ,everything from tendons,laminitis ,ligaments in my head and thinking the worst. She is my horse of a lifetime had her for 12 years..
