I've raised £500 to help my daughters pug doug who needs an operation to remove a lump that could save or end his life. he is in discomfort and desperate

My daughters pug doug is poorly. He grew a lump on his side a few weeks ago and has been to the vets and had biopsys done. The results have shown that the lump needs to be removed asap. It's showing as angry cells that if annoyed or if he catches it cud be disastrous for him. He was a litter of 8 with him being the only one t survive after an emergency c-section. I hand fed him and My daughter who's now 8 helped and she fell in love so he become part of the family and he turned 3 in May this year. My daughter is very upset as she don't want to lose her dog I just can't afford the amount. I've rang around literally every vets and charity to help or even set up a payment plan but wit's no luck.His a healthy happy little pug normally but now has started to whimper when he gets up and the lump has now split open and is red and inflamed, the vets have told Me it's not an easy operation and it does need doing to prolong his life so im asking for any help to make my daughter happy and have my pug back to his normal self again. His operation is set to be betwren 5-600£ For removal,pain relief,boiopsys once removed and care etc
