I had a pony go lame several years ago, and the vet used at that time wanted us to put that poor baby in a trailer and haul her in. Um, no. Poor baby couldn't have jumped in the trailer to save her life. He finally came out...two days later. We had already called our farrier, who was pretty good at diagnosing lameness issues. Nothing broken, but our farrier and the vet got into a shouting match about wheter it was in injury to her shoulder, knee or hoof. Vet said founder, because she was a shetland. Farrier said no way, perfect hooves, no pain - gotta be in her knee or shoulder. Vet said couldn't be her knee, wasn't swollen. That left her shoulder. I didn't think it was her shoulder - there was no heat and no pain there. We had the pony on bute for a month. She eventually healed up and walked sound again, but we never did figure out exactly what was injured. We know she fell down the back side of the dam, but that's all we ever knew for sure.
