She now did this after getting up from a loong long 2 or 3 hr nap , after doing her downward dog and cat stretch , stretching down then back into a normal position she whined and turned to her left hind side , muscle cramp ?, stifle stuck?, is really weird I've squeezed every place it might be and nothing , she does go into a sit when I'm around her back end and squeeze her back end ? Could that be an issue ??
