How is Shilo doing? I know exactly what you are going through and I hope from the bottom of my heart that the Baytril has shrunk the lump. If not, and you need to talk or want to talk about any of the things I had to have done to diagnosis Sydney, please message me. Hopefully, I could help you skip some steps so you could get Shilo on tx faster. You guys are in my prayers and thoughts.... Please keep us updated.
