Reitbeteildigung auf Allrounder Ponystute

I am looking for a reliable and trustworthy riding partner for my pony mare Belanie. Belanie is approximately 1.50 meters tall and 19 years old.  
My mare is completely fearless and truly versatile—she enjoys everything from dressage and jumping to relaxed rides in the countryside. She is comfortable with double longe, lunging, or riding without a saddle. Belanie is sweet, but she needs someone who can give clear guidance and assert themselves when necessary.  
Not suitable as a weight carrier!  
We are seeking someone for three days a week.
