Dogs hind legs paralyzed after jumping around. Will she recover?

Did you vet give you any treatment for the meantime? Hopefully they told you to keep her on strict cage rest--many cases of spinal cord compression (that comes from a disc bulging or rupturing, and soft tissue swelling) may improve and even return to normal with cage rest and anti-inflammatory therapy. However is it important that right now in the early stages that they provide something for inflammation, and that you keep her exercise strictly restricted to a cage and only going out on a leash to go to the bathroom, unless you can be *right there* with her and make sure she is being quiet. This could last for weeks, even months, but usually you will start seeing gradual improvement. You may be able to do some physical exercises like moving her hind legs to keep the muscles working and prevent atrophy. Hopefully that helps and hopefully your vet can give you some more info tomorrow. You definitely need to make sure your pup can pee, and that her bladder isn't getting huge (a lot of time they will just dribble constantly with a smaller bladder--so you need to keep her clean and dry), and that she can eat and drink ok.
