My horse has been fighting an abscess for about 4 weeks. It looks like it had come out through the heel.. Everything looked ok so I stopped soaking it for two days...well his leg swelled and he couldn't walk. So I called the vet and they put him on antibiotics for 10 days. Well it's the ninth day and he's still pretty bad and theres some liquid stuff kinda coming out. Is this normal??? The farrier is going to pull the shoe and pad to see if anything is going on under the pad that we can't see. I've never dealt with an abscess like this before. He still can't walk on it.
