I just picked my horse up from 3 months of being at the trainers and his feet look like this. I didn't look at them when we picked him up at 10:30 last night.
When I was at the trainers a few weeks ago, it looked like his frog was "growing" up the back of his hoof. When I asked about it, he said he was shedding his frog and it was normal.
My son knows more about horses than I do and he said he has thrush very badly and no frog left on any of his feet.
If this is not normal, will it heal, will he go lame?
