It’s thrush season!
Thrush is probably the most common ailment I see but a lot of people are uncertain how to spot if their horse has thrush. Below are some examples of healthy frogs vs thrushy frogs as comparison. A healthy frog should be full, firm and pliable and should make solid ground contact.
Thrush takes these characteristics of a healthy frog away. It causes the breakdown and decay of the frog's sensitive and insensitive tissues making frog wane down below the heels and have cracks and crevices where the thrush is attacking. Most commonly Central Sulcus thrush is a deep “crack” that eats its was down the centre of the back of the frog into the sensitive structures.
Thrush can also thrive in the collateral grooves on either side of the frog.
For treatment of central sulcus thrush I have antibiotic and antifungal syringes that I have had good success with. For collateral groove thrush and preventative if you notice any crevices starting in the frog I like the BioPteq. I will be carrying both with me and can let you know which I recommend depending on what kind of thrush your horse has.
