Thrushy feet (NB. the photo used is a stock image from iStock if anyone is looking to provide advice)
Each and every horse owner will probably have to deal with thrush at some point. It has nothing to do with improper horse care or unhygienic living conditions (although these undoubtedly exacerbate the problem). This autumn, with its damp, dewy mornings is proving to be a very thrushy one!
Thrush is a bacterial and fungal infection that can eat away at the tissue of the frog in the hoof. These fungi and bacteria are more common in damp environments and prefer moist soil, and in these conditions mud packs into the hoof sealing off the air and giving them the anaerobic conditions they thrive in – this is why picking out feet is so important. Even so, the bugs causing thrush can still cause issues in dry weather, especially if horses are living with sheep because the main bacteria causing thrush is prolific in the guts of ruminants (and in their poo).
The area near the back of the frog, known as the central sulcus, is a tiny indent in a healthy hoof, but in the damaged hoof, it is a profound crack. Thrush typically begins to affect this area initially and starts to eat away at the healthy tissue, making a home for itself in the frog's sulcus. For the thrush to flourish and consume more healthy tissue, a deep sulcus provides a great hiding place – it’s difficult to get at.
So what makes thrush a problem? Early identification is key. It’s relatively simple to get on top of minor surface thrush. Daily use of Frog & Sole Saviour after picking out the feet will sort out any bugs taking advantage of ragged tags on frogs as well as minor infections of the central sulcus. More severe cases of thrush may take weeks or even months to resolve, especially where heels have contracted and sheared. As it reaches this advanced state, it can be quite difficult to break the vicious cycle.
If thrush goes untreated and eats deeply into the frog tissues, your horse may have sensitivity when loading the rear of their hoof. This altered movement pattern causes compensations elsewhere and the digital cushion will slowly degenerate as the heel area isn’t working as it should, allowing the heels to contract further, and so on. It becomes a vicious cycle. Ultimately infection of the deeper tissues is extremely painful, and you have a lame horse.
Proper hoof care is an essential part of dealing with these more chronic cases, and breaking the cycle isn’t easy – bringing the back of the foot back into function and undoing the contraction while keeping your horse comfortable. Frog & Sole, and I often recommend adding additional oils in chronic cases which are sore, is helpful as it has the ability to pe*****te the frog tissues more deeply than most topically applied products. But it won’t uncontract the heels, the shape of the hoof capsule has to be helped as well to regain a healthy, functioning foot..
