Saving Camilas heart

Hi! My name is Adilene and my puppy is Camila. Camila has a heart murmur since she was born, we believe it is the Patent Ductus Arteriosus. To ensure she lives a healthy and long life Camila will need to have heart surgery to correct the artery that didn’t close when she was in the womb. Cardiovascular appointments alone are very expensive and the surgery will be more and I’m scared I won’t have enough myself to support her. Recently she has been dry coughing more than normal and that’s a side effect of heart failure. It scares me to death and I hate seeing her little confused face. I recently moved in to my first apartment and she’s all I have. Anything that you can donate would help tremendously. Please help me save my puppy.
