Osteosarcima treatment and prognosis

Hi, we took our dog to the vet about 6 weeks ago when we thought he had hurt his leg chasing a ball, his ankle was swollent and we have just been back today to have her tell us she thinks it may be a bone cancer. She has X rayed him again and while she can’t see a mass the joint is still swollen. We have to rest him and if he is no better he’ll need a biopsy in either Nantes or Angers.



Does anyone have any first hand experience of either of these two vet hospitals or of a dog with this disease. Treatment seems to be amputation but even then the prognosis doesn’t look too great. So any advice would be much appreciated…
