Charming's leg amputation surgery

Hi, my name is Jennifer. I am trying to raise money for my 7-year-old golden retriever dog, Charming. He was recently diagnosed with cancer in his toe. Unfortunately, the tumor is dying and causing an infection. The only way we can save him is by removing his whole leg. He needs surgery as soon as possible, which costs between $4-5k. Any donations would be greatly appreciated. Thank you so much <3
