One of the most common injuries in yoga practice occurs in the lumbar spine. Many that report suffering from this injury practice a Vinyasa style yoga regularly which involves this particular transition, so this cue is vital when teaching this transition. One student admitted to suffering an injury from this exact transition (NOT from my class :-) ) that led her to require physical therapy.
All that being said, please read carefully, listen to your body, and be mindful in your practice. Yoga should feel good. If it doesn't, then skip the Vinyasa.
To start, let's break down the poses and this tricky transition so that it can feel like the joyful process that it was intended to!
Upward-Facing Dog
Line up your wrists underneath your shoulders and hug your navel in toward your spine as you press your pelvis down. The tailbone should be drawing back and down toward your heels. Maintaining this same pelvic alignment, spread and press all ten toes into the mat.
Begin to press the ground away from you as you lift the upper body until arms are comfortably close to straight. Thighs, shins, knees, and ankles float off of the mat as you lengthen through the upper body, keeping the shoulders away from the ears. Keep the chest broad and the shoulders in line. Remember that the front of the body is extending in this pose, so the back muscles are engaging to help get the job done. Don't dump heavily into the wrists and shoulders in this pose, use your body as a whole! The tendency is to want to look up, but this usually leads to wrenching the neck when not done properly, so I like to keep the gaze forward and lengthen through the crown of the head.

Transition
Draw a deep breath in through your nose here, then shift your attention to your core muscles before lifting anything. Keeping the drawing of the navel in toward the spine and extending the tailbone downward. Use this core flexion to start to lengthen through the sitting bones, and lift them back up into downward facing dog.
Practice this transition again and again and say goodbye to low-back pain in Vinyasa!

Perform
Make sure that the supporting hand isn't directly below its shoulder; position the hand slightly in front of its shoulder, so the supporting arm is angled a bit relative to the floor. Straighten the arm by firming the triceps muscle, and press the base of the index finger firmly against the floor.
Firm the scapulas and sacrum against the back torso. Strengthen the thighs, and press through the heels toward the floor. Align your entire body into one long diagonal line from the heels to the crown.
If you'd like you can stretch the top arm toward the ceiling, parallel to the line of the shoulders. Keep the head in a neutral position, or turn it to gaze up at the top hand.
Stay in this position for 15 to 30 seconds. Come back to Adho Mukha Svanasana, take a few breaths, and repeat to the right side for the same length of time. Then return to Adho Mukha Svanasana for a few more breaths, and finally release into
