Daisy has a tumor

Daisy has a tumor in the bone of her toe that needs to be amputated asap. The sooner we can have this completed the better chance she has. We hate to ask for help but we are desparate. Thank you!

We rescued our beautiful Daisy 5 years ago when a friend of ours shared a "help me" post from Big Dawgs Rescue (Northern California). A family was cited by the city for having too many animals and had so many days to find her a new home. We fell in love with her photo, as you can see she is quite beautiful. BUT we already had 3 chihuahuas. Yes we are looking at this beautiful Staffy while we have chihuahuas at home. Well she was coming from a family with 5 yorkies so we decided to chance it. Needless to say, she thinks she is a small chihuahua and you can't tell her different. We love all of our dogs but there is something about Daisy. She knows when my anxiety is getting the better of me , she sits beside me and leans into me. Almost like she is hugging me and I immediatley feel some release. She loves to snuggle and have her her head squooshed (massaged). She will be 7 years old this December (seems far too young to be dealing with this). We want to do everything we can to help her live out the fullest life possible. If that means cutting off her toe then that is what we intend to do. It is amazing how much a toe removal costs and this may be only the first step depending on the biopsy. We had a terrible experience at our first vet. They ignored us when we said it was her foot. Over charged us for taking xrays of her knee and hip, NOT HER FOOT. Basically postponing the diagnosis over a month. We are now in great hands with our new Vetrinary office. Today we had Xrays taken of her toe again to find the tumor has grown since the last xray was taken (maybe 2-3 weeks ago). We also took chest xrays to see if the cancer has spread. There are spots that concerned the Dr. so we sent them to a radiologist for further diagnosis. I hate to say this is only the beginning. We could have a journey ahead of us. Any help you can provide is so greatly appreciated! Thank you all in advance!
