It's a really long story, but he was kept at my Aunt's property, along with another horse. When he was healthy, he was AMAZING. He was my heart horse, so it was a very, very sad time in my life.
The owner was a POS. I worked with his horses for their benefit. I bought their halters. I bought tack for them. I could never get permission to deworm them or anything like that. The only time they ever had hoof care was when he had shoes put on after he foundered.
I had never even seen the owner. Ever. (But I did have his expressed permission to work with them.) After they were auctioned (yes, likely sent to slaughter) I have never been back.
And I offered to buy this horse SO many times through the years. He always thought he was worth more than we were offering, even after he was dead lame.
-sigh- He was a wonderful, wonderful horse and I miss him every day. I learned everything from him.
