Peeling fork: normal or worrying?

When treating a thrushy frog with ozone — particularly with the Bagging protocol (gaseous ozone) or with ozonated oils — it is common to observe a surprising phenomenon: a complete shedding of the frog. This "dead skin" that detaches can worry owners... when in fact, it is an excellent sign of healing.

This article explains why the frog sheds, how ozone accelerates this process, and how to distinguish normal shedding from a pathological sign. To understand thrush disease as a whole, consult our complete guide to thrush.

Understanding Frog Shedding

The frog is living keratinized tissue that naturally renews itself. When affected by thrush (fungal and/or bacterial infection), the tissues become spongy, foul-smelling, friable, and sometimes painful. When the environment is reinfected or too moist, the frog produces poor quality tissue that remains attached to the surface. It is this unhealthy tissue that is seen "shedding" during treatment.

Why Does Ozone Trigger Visible Shedding?

Ozone deeply sanitizes

In Bagging, gaseous ozone eliminates fungi and bacteria, oxygenates tissues, and activates local circulation and repair mechanisms. Under the effect of ozone, the infected tissue stops being "nourished" and detaches naturally.

Ozone selects, it does not strip

• Dead tissues → eliminated
• Healthy tissues → preserved

It's like treating a skin wound: ozone promotes natural debridement. This is not deterioration: it is biological cleansing.

Typical Progression Observed

• Session 1-2: The frog begins to peel off in layers
• Session 3-5: Dead tissues fall off, a firm frog appears underneath
• Session 6+: Regrowth of a healthy, elastic, and odorless frog

If shedding appears, the treatment is working.

What You Absolutely Must Not Do

• Aggressively scratch
• Cut off loose flaps with a farrier's knife "to tidy up"
• Add acidic or drying products (hydrogen peroxide, bleach, methylene blue)

Ozone replaces antiseptics, antibacterials, and antifungals. The more you let the body do its work, the healthier the regrowth will be.

How to Support Shedding with Ozone?

1. Ozone Bagging (20-25 minutes)
2. Application of OZONE SOIN SABOT to the frog (barrier + sanitization)
3. Follow the complete thrush protocol

How to Know if Shedding is Normal?

Normal shedding:

• No strong odor
• Frog quickly becomes firm underneath
• Horse does not react to probing

Cases requiring veterinary advice:

• Extremely painful frog when pressed
• Deep crevice with abundant discharge
• No improvement after 5-7 sessions

In 95% of cases, the shedding observed during ozone treatment is natural debridement, a sign that the sanitization is effective.

Conclusion

Frog shedding is not a problem: it is the solution. Ozone eliminates the germs responsible for thrush, triggers the removal of diseased tissue, and reveals a healthy frog ready to regrow. If the frog sheds, it means the hoof is getting back on track.
