Gemini has Cancer

My little girl Gemini was diagnosed with mass cell cancer and is scheduled for surgery on July 23rd. She is my emotional support dog and is also my sons best friend. I could never imagine that at 5 years old she is having to go through surgery to remove a cancer tumor and we still don’t know the extent of the cancer until after her surgery. She may need chemo or radiation but we will not know until after the surgery god willing this is an isolated case they will remove all the cancer and she will go on to live a happy and healthy life. I am asking for some help to pay for her surgery for I am unable to come up with all the money right now. I was able so far to get together almost $300 and am just looking for any help that anyone can offer to help pay for the surgery. I will attach a copy of the estimate that the vet sent me with the cost.  Thank you in advance for any help you are able to give to us.
