My dog has been on a few medicines for the past few weeks for a supposed back injury. She was taking robax, another pain med and prednisone. I am starting to wean her off the prednisone as instructed by the vet. She is also on cyclosporine for an immune problem. I noticed the last couple nights she seem to smell like burning rubber. It also seems like perhaps she had peed on herself as her leg has been wet. This hasn't been happening during the day so I wonder what is going on. I've just washed her with soap and water to get rid of the wetness that was on her leg and bum. should I be rushing to the vet or is there something else I could try first?
