Losing a cherished pony can be deeply painful, especially when they've been a special part of your life. You might say something like:
"I'm so sorry for your loss. Your pony was truly beautiful, and I know how much joy and comfort they brought you over the years. Their gentle spirit and the memories you shared will always remain in your heart. I'm here for you if you need anything."
Expressing empathy and acknowledging the unique bond helps show support during this difficult time.
