I'm new to this forum, but it seemed a good place to chat with other horse owners. We just bought an older welsh pony (25). She is a bit stiff in the hocks, which doesn't seem to bother her when my 7 yr old rides--Ginger will trot etc. without any problem. However, twice in the last ten days, she has laid down and not been able to hoist herself back to her feet. If I put a halter on her and pull, it has given her enough bracing to manage to get to her feet, after which she acts stiff in her hind legs for a few hours. I'm concerned that at some point we'll not be able to get her up if her legs are too locked up, and wondered has anyone else dealt with this before? Any suggestions?
