Looking inside the walk-thru / escape door, we see the standard heavy-duty feed bags. One bag is open, one is closed. Feeding your horses this way (instead of from trailer “mangers” or hanging hay-bags) is cleaner, safer, and much healthier. It allows your horse to eat with its head and neck naturally positioned and to lower its head to cough when needed to clear its sinuses and throat. Please see the extensive section in our reference book on the importance of proper feeding techniques when trailering.
