HELP save Brady, 11 week old Great Dane

Our 11 week old Great Dane puppy, Brady, has been in and out of the hospital over the last 2 weeks. We were finally able to find out what was wrong with him after multiple vet visits and tests.  We have already spent thousands on his testing and diagnostics, and during this time, are not able to contribute more to saving our little guy.  The surgery he requires to save his life is $3500 minimum.  Brady has only been in our home for a short 3 weeks and has spent half of his life with us diagnosing his issue. We have put all of our time, effort, and money into making sure he can live a full and happy life. Anything that you would be able to donate during this time would mean the world for my family.
