Preparation

Quantity
A few large leaves or a small chopped heart per day.
Notes
Completely safe for overweight horses because it has virtually zero calories or sugar.
Nutritional Benefits
* Provides a massive boost of hydration.
* Extremely low in non-structural carbohydrates.
* Offers a tiny bit of roughage to keep the mouth busy.
Safe Varieties
1. Fresh romaine hearts - The absolute best, super crunchy and clean.
2. Loose romaine leaves - Great for tearing up and mixing in feed.
3. Iceberg lettuce - Safe, but has zero nutritional value, just water.
4. Spring mix - Safe in small amounts, but often gets mushy fast.
5. Slimy, wilted lettuce - Avoid entirely, it can cause stomach upset.
Feeding Guide
Average adult horse: 3 to 4 large, crispy leaves.
Overweight/IR horses: Feed freely as a completely safe, zero-sugar reward.
Seniors: Tear it up; the crisp water is great for dry mouths.
Positive Signs
* Enthusiastic, loud crunching.
* Reaching for more without getting a sugar high.
* Healthy, normal digestion.
Negative Signs
* Completely ignoring it because they want a real treat.
* Mild diarrhea if they eat an entire massive head at once due to the sudden water intake.
Preparation Science
Romaine lettuce lacks the complex, gas-producing fibers of cruciferous vegetables or the calcium-binding oxalates of spinach, making it the safest leafy green for equine digestion.
Enrichment Science
The crisp, snapping texture of the romaine spine provides highly satisfying tactile feedback that relieves boredom in stalled horses.
Play Ideas
Easy: Toss a whole, washed romaine heart into their feed tub.
Medium: Scatter torn pieces across clean grass to encourage slow foraging.
Hard: Tie a bundle of romaine leaves tightly to the stall bars so they have to bite pieces off.
FAQ
Q: Can I feed the white crunchy part at the bottom?
A: Yes! That is actually their favorite part because it holds the most water and snaps loudly.
Q: Does iceberg lettuce work too?
A: It is safe, but it's basically crunchy air. Romaine is much better.
Alternatives
* Spinach is risky due to oxalates, romaine is perfectly safe.
* Kale causes gas, romaine digests smoothly.
* Cucumbers offer similar watery crunch but in a different shape.
Risks & Disclaimer
Romaine lettuce is wonderfully safe, healthy, and hydrating. Just make sure it is fresh and crisp, as slimy, rotting lettuce can upset their stomach.
