Post 2

This is Thor.  A dog that stayed for a week at a boarding kennel that I work at.  He touched my heart as soon as I laid eyes on him.  He would come up for scratches with his little puppy dog eyes, but what was interesting, like most dogs, when you scratched between his shoulder blades he would shake on of his back legs.  Dogs shake their back legs due to a reflex that the touch receptor in that area put off. When a prolonged signal is being sent from that area the signal is sent from there to the signal cord for processing and back through the central dorsal horn to send a motor signal telling the leg to shake.   Reflexes are processed in the spinal cord.
