Jack’s new grooming brushes arrived this week. They work so well on his freckly white coat. He’s beautiful and strong, and now he is almost shining. I spend time over each muscle on his powerful neck shoulders and quarters. We built these muscles together, up hills, along the beach, through the forest, over fences, in looping dressage movements. I work him on the lunge, helping him stretch out his back and his neck. No one can see the muscles he’s built in me, the ability to endure, the strength to keep going. He carries me to pure joy.
