Hi there I am the one with the little guy in the wheelchair... His is his back legs but they do make wheelchairs for back legs.. Please if you have a minute check out Babybear's dogster page at
Dog profile for Wheelie Boy Babybear, a male Yorkshire Terrier you will see him in his wheelchair.. But I have to ask are you seeing your regular vet or are you seeing a specialist?? I would recommend seeing a specialist and does your doc know for sure with xrays that it is a disc?? Please if you would like PM me and I will try to help with more information.. I am here for you if you need information..
I am so sorry to hear about your baby still being in pain..
