Sorry to hear of ya'll loss. It's always tough to loose a horse. No matter the size. They all have heart.
We had to put Lil Lilly's first barrel horse down last summer......Even tho she knows this kinda thing happens when you have animals, that was one of the hardest days of our lives. Was a rough couple weeks after that for sure, cuz this ole mare would come to the yard gate ever day, twice a day to be let in and fed. She was the one I hollered for at feedin time, or Lil Lilly...which ever one of us was feedin, and they all came to her name. Took a while for them to learn to come to another name LOL I knew I could go out and holler her name and the rest would come, but I just could NOT bring myself to do that.
