My Molly girl was just picked up from the groomer's and not she is holding up her back left leg. I have palpated her knee, hip, and foot...she doesn't cry out in pain. No stickers in her paw either. I called the groomer's and they said she was fine when she went out to potty and they didn't notice anything. When my husband picked her up he said a very little girl brought her out...I hope she didn't drop my baby

I am kind of grasping here but I don't know what could be wrong. She looks pitiful when she walks...kind of hobbling but she doesn't seem to be in any pain. My vet of course is out of the office today. Should I worry or wait?
