Drs Roger and Karen discuss the differences of chemotherapy for dogs and cats that have cancer in comparison to chemotherapy in humans. Drs Karen and Roger discuss that consideration for choosing chemotherapy should be taken under consideration with the ultimate goals of chemotherapy in veterinary medicine, the subsequent side effects and effectiveness of chemotherapy as the result of these goals. Cancer is the number one killer of dogs and the number two killer of cats, so the probability that your pet may contract cancer and are one day faced with important treatment decisions is high, so this is a very important episodeto listen to even if your pet is currently perfectly healthy.
