I'm not knowledgeable in this domain so I want to see other people opinions about this. It makes sense to me what they do there but it's very simplistic and because of that I don't know what to think about it.
So what do you think?
"7NAIL reduce unwanted wear and tear of the hoof and at the same time allows the natural mechanism of the hoof." (this is from their site)
This is their site 7Nail nail system for better hoof care .
I will put a video about it and some photos with a case posted by some friends of mine. The photos are not very good but I can take photos myself because the horse is in another part of the country.
