Spindles have a relaxing effect on Charlie.
He especially likes to settle down on the floor right underneath me as I spin, and fall asleep. All my recent Ravellenic Games spinning has led to some quality canine naptime!
He's always been this way - he was just one year old above. When he was a puppy I would bust out the spindle to relax him when he was being, well, a GSD puppy. Instant calm, every time.
I love my sweet Spindle Dog.
