Best hoof oil for hardening?

[ruby92]

I know there is a lot of different hoof oils on the market but can anyone recommend one that hardens the hooves?
Thanks in advance

Nothing really but if your horse is sensitive to stones and hard ground, hoof armour is really good used it on both of my horses when they went barefoot.

Oil won't harden anything.

Formaldehyde (Keratex is 8% formaldehyde) will.

So will turpentine and it smells a lot nicer

Why are you needing to harden the hooves, though? An external application is a stop gap only, you need to achieve this through diet and work if possible.

Use hoof amour if they have no shoes and your wanting to make the hooves a bit tougher.
