Dew poisoning, also referred to as pastern dermatitis or grease heel, is a painful skin condition that typically affects the lower legs of horses turned out in wet grass or dewy pastures. It’s especially common in humid climates and during spring or fall weather shifts.
What Causes Dew Poisoning?
Dew poisoning isn’t caused by dew alone—it’s the result of prolonged moisture combined with skin irritation and opportunistic bacteria or fungi. Triggers include:
- Wet grass or muddy turnout conditions
- Photosensitivity from certain weeds or plants
- Insects or abrasive vegetation
- Compromised skin from prior wounds or dermatitis
Common Signs of Dew Poisoning
- Redness, swelling, or crusting around the pasterns and fetlocks
- Hair loss or thick, scabby patches
- Scabbing that may ooze or feel warm to the touch
- Sensitivity or lameness
- Often worse on white legs or in heavily feathered breeds
How to Treat Dew Poisoning
The first step is to dry and clean the affected area gently. Then, apply a topical like Rapid Relief Restorative Cream to soothe inflammation and help restore skin health. This naturally derived formula features calendula, chamomile, and vitamin E to support healing and calm irritated tissue.
Prevention Strategies
- Turn horses out after dew has evaporated
- Trim excess hair to reduce moisture retention
- Clean and dry legs daily during wet seasons
- Avoid pasture with photosensitive plants like clover or alfalfa
Why It Matters
Left unchecked, dew poisoning can lead to secondary infections and chronic skin sensitivity. With attentive care and support from products like Rapid Relief Cream, you can ease your horse’s discomfort and prevent future flare-ups.
