Hello dear horse friends,  
For personal reasons, I have to part with my beloved 19-year-old, 1.65m tall black gelding. He is suitable as a companion and is no longer rideable due to a minor issue (happy to share more privately).  
He would still be ideal for groundwork where he can use his mind.  
He is familiar with both open stabling and box stalls, and has been part of a mixed herd of mares and geldings, both large and small.  
We are looking for a suitable home where he can be a horse, be loved, and enjoy his "retirement life."  
For us, a good home is more important than the price. A 5-star home is what matters most to me.
