Sadie needs an operation...

My dog Sadie is almost 6 years old (a German Shephard Huskie mix) and she has a tumor that needs to be removed. I have also been hit with other financial burdens at the same time (my car just broke down on top of it) and am struggling to keep up. Her care has already exceeded $600 and I need to come up with the money for her surgery and post-care by June 6th of this year...
