Help to get surgery for Chelsea (dog)

This is Chelsea 

She is our 10 year old corgi. She is a companion to my mom who has survived 2 strokes and stage 3 lymphoma.  She is the Sam as if she was our child. I care for my mom full time so money is always very tight for us. 

Chelsea has what the vet says is a mammary cist on her belly.  It has progressively gotten larger.  The vet says it can be removed but the surgery is going to cost somewhere in the range of 2,000.⁰⁰.

It has become so large that it has started to scape against the ground when we go outside to go potty. 

She doesn't act like she's suffering or in pain. It seems like it's an uncomfortable inconvenience for her. However now that it rubs on the ground I fear that it can only get worse. 

If you or anyone you know,  could help us raise the money we need to get this surgery done,  we would be so grateful. 

Even with this problem Chelsea has to deal with, she still is in good spirits and still has some puppy energy at the age of 10. Chelsea still has some good years to live and be a part of our family. 

Thank you so much to anyone that can help!
