I just think it's a waste of money. Marketed to people who don't know any better and worry about their horse's feet, when in actuality it's the horses diet, environment or farrier that's sub-par. That's just my opinion of course.
What I DO use is Durasole on occasion, mainly because it really dries out the crevices in the hoof and opens them up to air and combats thrush and other greeblies. If a horse has a sensitive sole, Durasole treats that too.
But oily hoof dressings? I think they are just selling snake oil. Sure it looks pretty, but I personally don't think it does much else. If I put something on a hoof, I want it to do something like kill thrush and fungus.
But hey, prove me wrong. If you can give me a hoof dressing that also actually kills greeblies I would be open to using it. But I have had horses for close to 20 years and only used hoof dressing the first couple of years. And then I was like, WHY am I buying this stuff???
My horses are barefoot and have strong feet. I really think it's due to the protein in the alfalfa and the fact they are not on pasture. Other than some occasional treatment for hoof greeblies, occasional trimming and frequent rasping, that is just about all the care they need to stray strong and healthy.
Maybe stall kept horses need hoof dressing??? But my guys are in the mud, muck and pee as much as any stall kept horse so I don't know.
