Hi, I hope this is okay to post here - our 7 year-old mixed breed (maybe a golden retriever mix? she looks a little bit like a golden but colored like bernese. The place from where I adopted her said her mom was a border collie, so who knows?) has been limping since March. My wife and I live in two different states during the school year (we're college professors) and the dog's first veterinarian did an x-ray, saw nothing abnormal, and diagnosed her with arthritis. He put her on NSAIDs which helped a bit. Summer came, and I saw my dog's other vet, and she added gabapentin and continued the rimadyl. When we came back for a second follow-up last week (her fifth trip!) the vet decided to take another x-ray and saw clear abnormalities (a tumor?) around her distal femur. She mentioned OSA, but she and a radiologist said that if it's OSA, it's the strangest one she's ever seen, though that it was still a real possibility, but couldn't be certain, so recommended a biopsy. We're waiting on biopsy results now. My question - she doesn't show ANY other symptoms - she's active, eating, and generally the same as always. No weight loss. Is this typical with dogs with OSA after four months without treatment? We used to live in Utah, though it's been 3 years - is it possible for Valley Fever to manifest symptoms after years away from the southwest? I asked these questions to the doctor, but she didn't want to make any guesses, but here I am, waiting, and wondering. The doctor mentioned that it could be a less aggressive form of cancer, too. We're really happy she's doing well after the biopsy and is in good spirits, but of course worried, so curious if anybody has anybody information to share. Thank you!
