So I have a 6 yr old POA mare,, and I left on a family trip for 2 weeks, and when I came home, I get an email from my trainer, saying she brought Zoe (my mare) up from pasture because she had seen her limping in the pasture. She had extreme swelling of her hock, and had some blood poisioning and it took about a month and 1/2 for that to clear up. I was able to ride her once bareback when the swelling came back, and again, very severe. It has slightly gotten better, but its kinda at a standstill. I really need some advice!!! I was hoping to use this mare for show this year, but it looks like I have to use my 4 yr old instead, due to the fact that Zoe wont be ready by the time the season starts. Please help!!!!!!!
