What questions should I ask my veterinarian or veterinary oncologist before my pet begins chemotherapy?

Here is a list of questions you may want to ask your doctor before chemotherapy for your pet begins:

What chemotherapy drugs will my pet be given?
How will these drugs be administered (by mouth, under the skin or into the muscle, or through a vein)?
How will we know whether the drugs are working against my pet's cancer?
How frequently will my pet need to take chemotherapy?
How long will he be receiving chemotherapy treatments?
What can I expect the chemotherapy protocol for my pet to cost?
What side effects might I expect to see in my pet from these drugs?
What clinical signs should make me concerned? What signs should make me bring my pet in immediately for evaluation?
Who should I contact after office hours if my pet has signs or symptoms that make me worried?
