Ensure your dog is on a non-slip surface.
Support the abdomen or armpits, and hold them up into a human/bipedal standing position. The aim is to have them stretch to find the floor with their back feet, which in turn stretches out the hip flexors.
Only perform for the duration and repetitions that are set by your therapist, at the appropriate time set by your therapist.
