My whippet has corns. I e-mailed my vet the link to the Grassmere article and asked him to hull them.
He was very reluctant at first, expecting blood to flow at any moment, but he did it, and was super-impressed with how well the process worked. So much so the next time Rickie needed it done one of the other vets did it and another came in to watch and learn. It's pretty much a maintenance procedure but much better than surgery which, like many have said already, I would not consider as it doesn't have a good track record.
I now do it myself, but that isn't for everyone.
