Thank you all. Took her to the Vet, Doc says there is an injury, he said that he thinks there might be a  very tiny tear in the ACL , hopefully just pulled it so it is really sore. Going to wait a week and see if we need pictures. He also gave her some meds. She is passed out . My girlfriend called me today at lunch and said she got up on her own and started eating and drinking water just favoring the right real leg just a little. That gave me some hope. My little 43lbs Monster is one of the biggest things in my world
