Super quick question: I shod this horse first time on Monday and something looked weird to me. So I just pulled the shoe today again, cleaned up the hoof a bit and there it is! Should I start to sharpen the knifes? ;-) Vet will come out next week and take X-rays, horse is sound since around 6-9 months but had many issues with abscesses or lameness with suspected abscess before. Any ideas?
