Reminds me of my best horse. She would be asleep in her stall prior to track work or a race. Relaxed as.
When it came time to saddle up you'd scratch her head and and show her the saddle. She'd give her head a good shake and wakeup.
Next you placed the saddle on her back with the straps undone. She'd stretch each leg one by one then stretch as far forward with her front legs together and as far back with her back legs as she could with her stomach just about touching the ground.
When I first saw her do it I thought she was going to break every tendon in her body.
Once she'd done that she'd light up and mean business.
