My puppy Coco just had disc surgery and is showing movement in her back legs. She can walk but only with a wobble and she seems to be dragging her back legs. I know its only been a few hours since she's been out of the "pet hospital" but she just wants to lay. I've been trying to get her to walk a bit so she can get use to it but she stays in her doggie bed. Is this normal? Should I be worried? What can I do to help her walk normally again?

I appreciate any advice/suggestions. Thank you!
