Vet thinks the picture I sent of the stuff on the Animalintex looks more like thrush than abscess drainage. Waiting to hear back on some video clips and other pics I sent.
He does tend to get a little thrushy this time of year, but I guess I’d be surprised to have such sudden onset severe lameness like that with thrush. He does occasionally go out in muddy paddocks after heavy rains, but he is in overnight and his stall is cleaned twice a day. I also pick his feet out twice a day, and treat with Thrush Buster when I can see thrush starting.
I guess if it is thrush, I’m sort of stumped about how I can do anything more than I’m already doing to prevent it. The only other option would be not turning him out at all after it rains, and that’s not an option that will work for him at all.
