The thought of chemotherapy for a pet that has been diagnosed with cancer is very worrisome to many people because we think about the severe side effects that friends or loved ones have experienced. However, most dogs and cats do very well during chemotherapy because maintaining quality of life is extremely important in veterinary oncology. Our pets don’t understand that we are giving them a treatment that might make them feel bad because we are trying to help them live longer; they just know that they don’t feel well.
Therefore, medications chosen for cancer treatment in pets do not tend to cause side effects that people can experience. One of my personal cats is undergoing chemotherapy for a form of lymphoma, and he has a great appetite and he is acting like his usual, happy self. Many cancers once thought untreatable can now be managed for extended periods of time to give us more quality time with our beloved pets.
