We need answers for Tyson's mystery illness!

Hi everyone! My wonderful, loyal dog Tyson had been having health problems lately. We have discovered a mass inside of his nasal passage and swelling on the bridge of his nose. All of our initial tests came back negative. His biopsy came back inconclusive but ruled out some bad things. After paying for his two TPLOs, a hospital stay, and all of the testing done at my work, I need help. He needs to see a specialist. All funds raised will go directly to his vet bill. I would be eternally grateful for any donations you are able to make because I can't imagine a day without my best friend. Thank you, thank you, thank you. ❤️
