Mannix mouth cancer surgery

Hi animals lovers, my best friends 5 month old puppy Mannix has been diagnosed with a very aggressive mouth cancer. He's going to have a partial jaw removal to hopefully get rid of the part of his jaw that is affected with the cancer. The surgery is very expensive ($10,000). Unfortunately they didn't think at 5 months old that they would need pet insurance, so this is all out of pocket for them. Anything you can help with is beyond appreciated. If you knew my friend you know she donates to everyone for everything, I think it's time to give back to her. Thank you all for your help.
