Is palliative care best for my 14-year-old dog with a mammary lump?
Assuming Kara is in good health otherwise - which should be established with blood work and x-rays of the chest, to ensure that the tumor hasn't metastasized - then I would recommend proceeding with surgery. Mammary tumors can be quite invasive and aggressive, but depending on the grade surgery can be curative. Just because a dog is old, it doesn't necessarily mean they can't have anesthesia - you just have to take precautions, and find a vet who is capable of taking special care.
I would also get a definitive diagnosis as to what the mass is before making any decisions, There are lots of benign lumps that grow all over dogs' bodies, and just because this one is in the mammary area, it isn't necessarily an aggressive cancer. A fine needle aspiration biopsy can usually tell you what these are.
