Have there been no xrays done to confirm diagnosis?
I have a labbie girlie been on long term steroids for a few years now and she's doing well, has hydro weekly for her muscles but I've discovered a really good diet also helps so she gets everything from her food. She's not put too much weight on either although she says it's cos I don't feed her enough
I wouldn't have thought steroids alone would have an impact on a cancerous tumour growth (if it is) though....would need other adjuvenant therapy for that maybe?
Hope things continue to improve, sounds like she's doing well
