I've noticed just today more than any day how much Sonny actually cares for a Belgian/TB mare that is close to him. We got the owners permission to work with her and clean her up (owner hasn't ridden her in 1 year and they NEVER take care of her) and Sonny was calling to her the whole time.
After getting annoyed of the constant noise from Sonny I brought him back down to his pasture....and he kept calling and calling. He stopped when the mare was back in her pasture.
My boy is in love
