My sweet dog is an Alaskan Malamute. She is a rescue so we are unsure of her age but believe she is now between 8 and 10 years old. She started limping and we went to the vet. There was a large tumor in her leg but the vet was a bit perplexed because it was in an odd location for osteosarcoma (cancer.) We scheduled a biopsy a few days later but the very next day her leg fractured. Of course we did the biopsy, radiographs, blood tests and ultrasound and everything came back negative for cancer. My vet sent us to see a specialist at Kansas State Vet. school and he agreed that the tumor certainly looked like a cancerous tumor but we can't get a positive result. My vet feels we should euthanize her rather than amputate because she would have to take so much of the shoulder along with the leg. She has seen so many well-meaning people trying to save their animals and seen the animals suffer. If I knew she had cancer I might agree with her but we cannot get a positive result. I don't want to put a steel plate in the leg and try to save it and all of the physical therapy and bed rest that goes with it just to see the cancer show up and kill her a couple of months from now. Meanwhile the dog has spent all of this time in a sling: I will say this--she hasn't mastered pooping but she walks, trots, pees and gets around very well. We have pain meds for her which seem to work which has me a bit flummoxed because I understood that type of cancer was so painful that medication was useless. I know if she does have the cancer she has 2 to 4 months without chemo and maybe a bit longer with chemo. Does anyone have any experience with any of this? Btw--I am work typing this as I am without any means of communication (driving me nuts) so I can't respond quickly but any advice would be appreciated.
