Well it sure sounds like your dog has something like what mimi's & the OP's dog had which sounds not too bad. Roxy/Roxie-I only had her for a year & never even settled on a preferred spelling of her name-lived almost another 3 months after I first noticed the lump. I decided on no chemo because it doesn't cure, only delays, & the sickness it creates. The prednisone & pain killer helped her live a pretty good few months. (I started sleeping on the floor with her when she could no longer climb the bedsteps & gave her really yummy food in the end, so she was pretty happy.)
