Hello, we are raising money for our son's dog, Tonka. He was a normal pitbull since we adopted him, and then last week, he woke up and his back legs wouldn't work. We took him to the vet, and they told us that he may have a bulging disk in his back, but to confirm, they need to do an MRI. We don't have the money for that. So they gave him meds and sent him home. The dog is healthy, and we have got him a cart thing so he can walk. We are trying to raise money for the MRI that we were told would cost 2 grand. We just want to find out what is really wrong with him. Thank you if you can help. See the video below
