Should I have surgery performed on my dachshund back due to a ruptured disc?

Four days ago I went to pick up my Dachshund to put him down on the floor and he yelped in pain. He was able to walk fine at the time. I took him to my vet where he took xrays and diagnosed him with a stage II disc rupture. He gave him prednisone and a muscle relaxer called methocarbomol. I was advised to keep him from walking, jumping, climbing stairs and running so I did just that. He started having problems wobbling while walking and putting weight on his hind legs. However, when I read the discharge papers and talked to a technician they advised that I get him up often and exercise him by putting him on a leash and tugging a little to get him walking. He started walking again but can't walk very well. He is so exhausted and seems to just want to lie down. I took him to the ER Vet yesterday and they gave him hydromorphone for the pain. They recommended if the situation gets worse to meet with a surgeon. I don't know what I am suppose to do, let them operate on my dog or what. This is so confusing since he has feelings in his legs which I check every two hours since I was told if paralysis sets in then I would have a 24 hour window to get him into surgery. Do I wait for that to happen? I am going to meet with another vet for hydrotherapy and accuppuncture to see if there will be any benefit on top of the medical treatment. This just breaks my heart to see my dog going through this.
