Dogs and horses need to engage their hind end and flex the pelvis to get up. Commonly the sacroiliac joint on the right and or left sideof the pelvis is subluxated.
Chiropractic adjustments along with specific exercises will help this problem.
Usually i evaluate the entire muscle skeletal system since compensation does occur.
