Amanda's Beans 9/17 surgery

Hello Dodgerslist members. I desperately need your advice. September of last year our dachshund Beans had fibrosarcoma and a tumor was removed from his mouth. Thankfully this was caught early and has not returned. Then in February of this year he slipped a disc (He had had two previous incidents in 2011 and thanks to dodgerslist recovered with crate rest and metacam). He was dragging his back legs and dribbling urine. We decided on surgery and rushed him to an emergency centre where he underwent a pediculectomy on on the left side T12-T13 and the surgeon also fenestrated. The day after the surgery they stated that there was some pain when they pushed on the surgery site so they indicated that if it did not subside they may need to go back in. Thankfully the next day he was doing much better and they advised us they did not need to do another surgery. Beans continued to improve at home every day and was walking and even trying to run 6 months after the surgery and also had full bladder control. Then in late August he he experienced another slipped disc. After much debate and going back and forth due to financial reasons and not wanting to put him through another surgery we decided to have a second surgery done to fix the disc on September 17th. Another Pediculectomy was done this time on the right side T11-T12. Beans came home and has showed continuous improvement again. He is able to stand on his hind legs for about 10 seconds and both legs have a tiny bit of movement. For example if i tickle his foot he can kick with his left leg and just the other night we seen him stretch extending out his back legs. He is eating and drinking like normal and doesn't appear to be in any pain when we pick him up. He does not have bladder control. We have been placing puppy pads underneath him and when he urinates it does stream out but he has not been able to go on his own yet at his normal pee places while in the sling and does not seem to know yet that he needs to go. Today we had a follow up visit with his neurologist and she pressed on his back for pain and was able to make him flinch and almost cry out when she did it. She is now recommending that we again have an MRI and if it shows disc material still left from the previous surgery compressing his spine to do another surgery. The clinic is offering to cover half the cost of MRI and most of the hospital stay. We have no idea what we should do. Any advice is appreciated. We have to make a decision by Tuesday. They are first going to try medication (dexxamethisone). We are both heartbroken. We love him so much and don't want to put him through another surgery but we also don't want to take any chances because we do not want to lose him. Has anyone had this happen? What would you do?  -Amanda
