Cancer treatment for my dog, Bosco

This is Bosco, our 9 year old German Shepherd.  Our vet believes he has Osteosarcoma, which is an aggressive, painful form of bone cancer.  We are looking at needing to pay at least $9000 for surgery and chemo.  

We are needing to come up with the money within the next couple of weeks, as we need to schedule surgery soon, since the cancer is so aggressive.  It is our understanding that this surgery will get rid of the pain, and the chemo should help keep the cancer from spreading.

Bosco is usually a high-energy, fun loving dog.  He is professionally trained and works with a dog trainer to help rehabiliate aggressive and disobedient dogs.  So he brings a lot of joy and help to people who need him.  However, he is currently in a lot of pain and on meds to help manage the pain.  He not only can't work, but he's now fighting for his life.

We are in a jam and are hoping we can raise the funds to help save Bosco.   So time is not on our side.  We simply cannot wait to have the surgery.  Thank you for your consideration and help.
