Save Franklin

I thought everything was better but today I'm coming to all of you with some bad news. As you all may know, my dog Franklin has been in and out critical care for over a week now, diagnosed with a Pneumothorax. He had a surgery a week ago and has been back twice since.
I have had Frank since he was a young puppy, when a person was actually selling puppies in a WalMart parking lot. He has been at my side since that day, over 3 1/2 years ago now. We have done everything together, including our move to Denver last year.
Frank is now needing a second surgery, as the air in his chest is forming pockets, which prevent being able to pull the air off his chest. It is critical to keep the air off his chest to prevent his lung from collapsing.
Today I found out that Frank's only chance for survival will require another surgery. Currently, it is scheduled to take place on Monday. The clinic has been working to keep my costs down as much as possible for this next surgery, but it will still cost an additional $3900+. His treatment has already cost me over $10,000.
I am asking for any help you may be able to provide. Frank is my family and I want to do everything I can to keep him with me, healthy and happy.
I cannot thank you enough for your consideration!
