Please help! Koko needs life saving surgery!

Hi everyone, I really hate to ask anyone this during such trying times but I need as much help as possible. My baby girl Koko needs surgery, they have found a mass on the lower lobe of her lungs. With all the testing and night spent in ICU I spent $5,000 already and now have been quoted for her surgery $8,700 -$10,900 and possibly chemo on top of that. Here’s a little bit to know about how I was blessed with Koko. 4 years ago I lost my first dog Gucci that I had for 10 years to stage 4 lymphoma, I fell into a depression after losing her. Six months later Kokos owners wanted to euthanize her for crying at night which I couldn’t believe and couldn’t let her go to a shelter. As depressed as I was and felt guilty thinking I was trying to replace Gucci I could not let her live another horrible day. The day I went to pick her up was actually the day after my birthday, I felt like Gucci sent Koko to me knowing we both needed each other. She is by far the best birthday gift I could have ever asked for! Many may think that I rescued her but she rescued me, she made me happy again, she gave me the love I was missing for the 6 months I was without Gucci. I’m sure she didn’t come from the best life hence the owner wanting to euthanize her but she is by far the most loving, sweetest, smartest, mushy girl and deserves to live a much longer life and 4 years together is not enough. If you can find it in your heart to please help me save my baby it would mean the world to Koko and I.
