Stronghorn Hoof Hardener Spray - 500 ml

Stronghorn spray nourishes and toughens horn tissue and is a powerful hoof disinfectant.  Its spray-on formula makes it easy to apply and more convenient than many paint-on hoof hardeners which come in narrow-based bottles that are easy to knock over.  We have made Stronghorn in a spray-on form using only safe ingredients (MSM, zinc sulphate essential oils and weak citric acid) it also doubles as a very effective antimicrobial!

Stronghorn contains:

  • Zinc sulphate - A powerful, non-caustic, antifungal agent.

  • MSM - A naturally occurring source of sulphur to promote the growth of healthy hoof tissue.

  • Lemon Oil - An essential oil with antibacterial and antifungal properties.

  • Elemi Oil - An essential oil with antibacterial and antifungal properties.
  • Citric acid - A natural preservative to extend the life of the product.




Clean the hoof. Spray product onto the underside of hoof and around any nail clenches, avoiding the frog unless it is very soft. Apply daily until improvement is shown and then phase to weekly applications over time. For best results allow to dry prior to work or turnout.





Stronghorn FAQ

Is Stronghorn easy to apply?

Yes, very 2-4 sprays per foot is all it needs, a little time on a dry surface to allow it to soak in is advised.


Should I use a hoof disinfectant like Sole Cleanse too?

No, Stronghorn is a powerful antibacterial in its own right so there is no need.


How often should I apply Stronghorn?

Daily at first if possible, then the interval between applications can be increased until horses prone to soft soles are having it applied once a week.


Does Stronghorn contain formalin?

No, we don’t believe there is any long term benefit to using formalin on feet so we do not use it in any of our products.


Case Studies


‘Peri’ a 4 year old Welsh Section B.  barefoot driving pony. His owner was noticing that he was starting to get sore on uneven ground and his feet were wearing quickly on roads.

Wary of using stronger chemicals on her horses hooves she tried Stronghorn.

The owner used it as part of her regular hoof care routine and found it very simple to use. Peri is now comfortable enough to drive without the need for hoof boots and the wear on his feet has reduced considerably.

“We are on the right path to rock crunching hooves and we couldn’t be happier! Thank you Red Horse! I continue to rave about you to anyone who will listen (such as my now converted yard owner and her 8 Shetland ponies!)”



‘Apple’ an 8 year old sports horse. At time of purchasing she had very overgrown, sore, smelly feet.

Despite soaking with cider vinegar and Hibiscrub daily there was little improvement to the state of them.

Stronghorn was applied daily prior to her being worked then holes were packed with Artimud prior to turnout.

Within a couple of weeks the feet were odour-free, had hardened up and were less sensitive.

A year on she can walk on stony lanes without showing any sensitivity, she strides out more confidently and her white lines are strong enough to not take on any smaller stones.

“I was surprised how fast Stronghorn worked, I just apply a couple of times a week now to keep her feet clean and healthy, I’ve ended up buying the majority of the Red Horse range, I won’t go back to chemical filled products again.”



Henry is a veteran cob. started using your product’s last January 2017, due to my friend recommending them and wow what a difference they have made to my Cob.

He has a condition called Chronic Progressive Lymphedema – CPL, which is an ongoing battle as this condition can also affect his frogs.

I started using your Stronghorn and if it wasn’t for that, my boy would never coped having his shoes removed last June 2017 and coping with the transition to barefoot after being shod all his life, he was 21 this year 2018.

He is in full work and I’m hoping to have back out competing later in the year (Affiliated Dressage) I do tell people what I use and people have noticed a big difference in his hooves and especially his frogs.
Just want to say a Big thank you to you all for your products and keeping my Veteran Cob hooves and frogs looking fab.

With thanks to Shelley Ayling.
