Canine Cognitive Decline Alters Gait

Researchers established that canine cognitive decline is directly associated with a shortened stride length in dogs' front limbs. Because thoracic limbs require heavy cortical control for balance and spatial awareness, their shortened stride serves as an early behavioral biomarker for brain decline.
