My rabbit of 9years got a tumor on the right arm and I send it for removal.After that the tumor grow back but the vet say only option is to amputate which I am against it. in order to prolong its life I have to wash the wound and bring it for injection everyday till 1fine day it could no longer stand on its own and shiver there then I send it to the vet to put it to sleep.
Bro if it can still walk around maybe you can reconsider?
