The reality of Phoebe's cancer has sunk in and I now know we don't have time on our side. Canine osteosarcoma is an aggressive, fast growing cancer. If it spreads to her lungs, we're done.
In a word, a few simple Google searches have given me hope. I'm not alone. I have lots of company. And I have a lot of evidence that if I decide to amputate, it doesn't make me an evil person.
I know in my heart that Phoebe is stronger than I am and if there's any dog that can live a fulfilling life on three legs, she's the one.
