As my vet always says “age is not a disease”. If they think she is a good surgical candidate, and I would be inclined to try it in a younger dog, then I try not to let age enter the equation. Jolie successfully had major surgery at 12, but at 14 had developed larngyeal paralysis and significant hind end weakness, so at that point we didn’t consider it. Depends on the physical condition of the dog and the chances of good longer term outcomes for me.
