1. The Stress Factor: Why Hauling Hurts

Transport is the #1 cause of gastric ulcers in performance horses.

Study: A transport study showed gastric erosion began within 12 hours of trailing in untreated horses.


2. The Medication Strategy (Ulcergard vs. Nexium)

Option A: The Gold Standard (Ulcergard)

Option B: The Budget Option (Nexium)

Option C: The Buffer (Alfalfa)


3. Hydration Hacks: Getting Them to Drink on the Road

Dehydration + Stress = Impaction Colic. Horses often refuse water that tastes “different” (chlorine/minerals) at showgrounds.

Tricks to Force Drinking:

  1. Flavoring: Add Gatorade powder, Apple Juice, or Peppermint Oil to water buckets at home 3 days prior. Keep adding it on the road to mask the new water taste.
  2. Soup: Soak hay cubes or beet pulp into a sloppy soup. They “eat” their water.
  3. Salt: Add 1 tbsp loose salt to grain to trigger thirst.
  4. Cucumber/Watermelon: High water content treats.

4. Feeding During Transport: Hay Net Safety

Rule: ALWAYS have hay in the trailer. Chewing produces saliva (bicarbonate). A horse standing for 4 hours without chewing has a stomach full of un-buffered acid.

Safety Tips:

  1. Tie High: Net should be at eye level so they don’t get a leg over it.
  2. Dust Free: Soak the hay or use low-dust hay. In a trailer, dust swirls into the respiratory tract -> Shipping Fever.
  3. Small Holes: Use a slow feeder net (1.5”) to make the hay last longer.

5. Upon Arrival: Settling In Without a Meltdown

The “Landing” Protocol:

  1. Unload & Walk: Hand walk for 15-20 mins immediately. Gets the gut moving.
  2. Offer Water First: Before hay/grain.
  3. Gut Support: Give a tube of Probiotic Paste (like Probios or Succeed).
  4. Familiar Bedding: Use a bag of your own shavings if possible to smell like home.
  5. Ulcergard: Give your daily dose NOW if you missed the AM dose.

6. The “Shipping Fever” Connection

Pleuropneumonia (Shipping Fever) kills horses.


7. Checklist: The Night Before You Load

Safe Travels! Prevention is cheaper than a vet bill at a show.
