Please help save my best friend zomvie!!

Hey everyone, as you all know Doug has had zomvie since she was a puppy and is more than a pet, she's family. She needs a surgery for a mammary tumor on her tummy. They also want to have her fixed while she is under, as hormones help the tumor grow. We have her son from her one and only litter and he loves his mama so very much. She's been through it all with us and now we just want our old girl(11yrs) to be able to spend as much time with our son, who absolutely adores her, over all the other pets. Please, ANYTHING, even a couple bucks helps! Unending appreciation!!
