Lymphoma is one of the most common cancers in dogs. Chemotherapy achieves good remission rates and dogs typically tolerate treatment well, maintaining quality of life during therapy.
Lymphoma transforms rapidly from apparent health to significant illness, and the decision about treatment must be made quickly. The good news is that the CHOP chemotherapy protocol achieves excellent initial remission rates and dogs tolerate treatment far better than the human cancer chemotherapy experience might suggest. Severe side effects requiring hospitalization occur in approximately 25% of treatment cycles but most dogs maintain good quality of life between appointments. The treatment goal is comfort and quality of life extension rather than cure, as most dogs relapse. Clear communication about realistic expectations allows owners to make informed decisions aligned with their values and their dog's welfare.
