Lasair had his second shoeing/trim yesterday. He is my 3 yr old OTTB. He gets front shoes only. Yesterday, he was shoed/trimmed at 10:00AM, then I put him away and gave him the rest of the day off to get used to his new feet. (I usually work him every day) Today, I do my usual routine to go work him. I trot him around in his pen a couple laps in each direction to check for any obvious problems, I pick his hooves, groom him, and gear him up. We walked through the backyard and got to the gate. A couple of steps after he walked onto the concrete driveway, he stumbled real bad. I watched him walk the next few steps and he stumbled real bad again. Then he started holding up his back legs and did the whole "walk on eggshells" routine. He is in OBVIOUS pain. ALL the signs of intense pain in both rear legs. I think I know what's wrong with him...but I need back up. Please look at these pictures and tell me what you see. I'm so worried about my baby, I'm on the verge of tears.
