The spleen can enlarge with certain infections (especially blood borne infections or tick borne disease), splenic torsions, or certain types of cancer. It can also be normal for some dogs to have a larger spleen, and certain drugs used for sedation or anesthesia can cause the spleen to enlarge. Your veterinarian might want to perform blood work to look for changes that could suggest an infection or may want to perform an ultrasound to examine the spleen as a next step. Some of these causes are very treatable and others are not.
