Thank you for submitting your question regarding your dog. I am sorry to hear about his diagnosis. The antibiotics will likely help provide him some comfort for a period of time. Pain medications will help as well. However, the cancer is a terminal diagnosis. When discussing quality of life, I want the patient to still be having more good days than bad days. The patient needs to be able to eat and drink adequately as well as having enough mobility to get around comfortably. Finally, I want the dog to still have some joy in his life. When these needs are no longer able to be met, then it is time to consider euthanasia. I hope this information provide you some objective criteria. Again, I am sorry for your situation.
