Oh, Bill, I'm sorry you had to get rid of Charlie and that he got hurt. You had to do what was best for you and them, though.
I'm kind of in the same predicament, but with our pony. He is the dominant one and Stella is at the bottom. He prevents her from going in barn also and he also gets the lion's share of hay when he needs the least amount. I don't have individual stalls nor a small paddock to separate him with. The only pets we've had that I felt had to go were a couple of goats. I've always been the type who gets an animal with the intention of having it for life, but this pony has just become a thorn in my side.
Stella - sweet, timid, elegant, lovely, lively, amazing
Luna - large, unattractive, naughty, adored
