My 6 month out Newfoundland puppy is having issues with Panosteitis "pano" (Growing Pains) and was given Tramadol and Deramaxx for pain and inflammation. Since that visit she has started having problems with a different leg with all the same signs. The problem is the vet said it can last for months and tends to only affect one leg at a time. I am wondering what is a good alternative to the Deramaxx for the inflammation as I do not have the money to go back to the vet again (cost me $600 for xrays and stuff last time and vet said he will redo them for each instance

. She needs the antiinflammatory but I can't afford another huge vet bill to redo tests that were already done and was told the condition can last for months.
Thanks
Mel
