Why giving your horses feet an opportunity to dry is likely a good idea but using hoof hardeners might make your long term goals more difficult to achieve.
From my experience, I struggle to find a significant correlation between ground sensitivity and wet feet. I see too many rock crunchers throughout the winter and too many sore horses with rock hard feet over the summer.
However, feet CAN suffer from prolonged exposure to the wet, particularly their frogs and soft tissue structures at the back of the foot. Those that suffer from central sulcus infections can be particularly susceptible.
During these soggy times, standing your horse in nappies for an hour or and then applying a gentle product such as Hoof Clay (from Horse Leads) or using ‘Soledry’ for horses in hoof boots; will protect your horses frogs from pesky bacteria that thrive in these anaerobic, wet, warm conditions.
These products are non corrosive, non toxic and are designed to respect the natural function & anatomy of the hoof. Used alongside appropriate hoof care with a holistic approach; you won’t go far wrong.
But what about hoof hardeners?
The most popular hoof hardeners will have ingredients such as formaldehyde; an ingredient used to harden and dehydrate wood, along side others, also designed in the treatment & longevity of wooden structures.
From my experience, I have not seen these products, in any way, aid ground comfort for the horse. Ground sensitivity is so much more complex than wet feet; we are rapidly realising the need for whole horse resolution in these cases.
Secondly to this, please practice extra caution if you are applying these products to aid a thin soled horse. It is unlikely that your horses soles are thin from external abrasion, wear or a damp environment; it is most likely an internal issue with the solar corium (soles thin from the inside 🤯). Thin soles don’t want to exfoliate. Applying formaldehyde to an already compromised thin sole could result in that delicate sole becoming dehydrated, brittle and potentially exfoliating when it doesn’t want to!
Please start from the inside and give any external products some careful thought, especially if they have hazardous warning labels on the bottle ☢️☢️☢️☢️
