My best friend recently brought her TB gelding out to be boarded at our house. We only have one large pasture available and a small dry lot so I have been slow to introduce them. They have been out at the same time where they shared a fence line and there were no problems at all (not even the smallest snort or ear pinning).
Today I opened up our side barn door which is actually a cement ramp leading from the main pasture to the stalls. I've been putting the TB out on the big pasture half the day and my stallion the other half the day so that the TB can get used to the pasture and be familiar with fence lines once they are turned out together. Poco (my stallion) walked right up the ramp and was standing in the barn aisle as I was throwing hay into his stall. I failed to realize that he had turned around and was watching out the door at the edge of the ramp and my best friend had let her gelding out into the pasture.
It was that moment my heart stopped as I realized that there was no way I could physically stop my stallion from going out after him if he so chose to. The gelding stopped and looked over at my stallion, my stallion perked his ears up, lifted one foot to step down the ramp and I softly said his name followed by "back".
Without the slightest hesitation he backed a couple steps, turned around, and came right to me. I just had to give him a big ol' hug and tell him good boy. I honestly believe we will have no issues turning them out together as they've shown absolutely no aggression to each other but I was still proud that from 20 feet away I could call my boy back from going out to meet a new horse and he obeyed. <3
