Oh dear, it seems to be my week for being controversial...Unintended, but things always happen in spates.
Apologies for the graphic photos, but this is what I found when I went to see an insulin resistant horse yesterday. It has had several bouts of laminitis in the last few years, and is under a local vet for treatment.
Obviously, due to its insulin resistance it is much more prone to laminitis than a normal horse, and so inevitably its more prone to abscessing.
At the weekend, the owner called the vet out as the horse was very lame and obviously had developed an abscess in this hoof. As many (but not all!) vets do, this vet decided that the only way was up, and started digging.
To be fair, the hole dug did allow the abscess to drain, but unfortunately the hole was made so deep that the vet is now warning of coffin bone infection. I hate to say it, but coffin bone infection is much more likely to be a problem if you dig holes so deep that you expose the coffin bone...
