Yes i call my vet dr. I had my black lab euthanized last March. I think she was about 13. I spent $900 on a cyst a year before she died. Then later she developed growths above her legs. Cutting them out would have involved severing nerves to the legs. As one of the above posts say, you will know when the time is right to euthanize especially if the dr. recommends it.
Hope this helps. Not easy having a sick/dying pet.
