We have a springer who had this surgery two years ago, his came on very quickly, he jumped in to the car and was fine, after a 20 minute journey he was was unable to move at all, we were on holiday in Somerset so rushed him to the nearest vets, the vet referred us straight to Bristol, where he was scanned that night and operated on the next day.
There was no improvement for 7 days, and he only brightened up when we visited, becoming withdrawn and refusing to go to the toilet when we left, so he had to be catheterised, on the seventh day we asked if he could come back with us to our caravan, vets weren't too keen on the idea mainly because they were worried about him refusing to wee even though he had control of his bladder, and because he was going to be high maintenance but we insisted on the understanding we'd come back the next day for checks.
Once we were back at the caravan he started going to the loo with me carrying and holding him in the position, after awhile I realised he was happier if I lay him on his side and walked away while he did his business, it meant he had to be washed after every toilet break, but that was a small price to pay for him going when he needed too.
After ten days he started to try and roll himself around when outside on grass, then once upright he would start trying to drag him self weakly with his front feet, progress was very slow, but after three weeks he could stand unsupported, if a little wobbly, but would fall over if he tried to move, a month after surgery he could walk short distances but would collapse if he took it too fast.
As I said progress was very slow, and after 6 months he was able to run, often collapsing in a heap if he tried to stop or turn to quickly, and he was till knuckling on his front legs quite a lot.
He had a 24 month check up recently and the vet remarked she would never guessed that he'd had the surgery, although after exercise he does tend to be a little wobbly on the pins, and his left side isn't as strong as his right side so he avoids jumping and always goes around obstacles.
In my experience, I'd say have her home, I'm sure she'd be happier there and recover quicker.
