Rectal exams are not routine for all pets but may be necessary depending on specific health concerns. For instance, if a pet is experiencing digestive issues, abnormal stool, or discomfort, a rectal exam allows the veterinarian to check for signs of tumors, inflammation, or anal gland problems. Older pets or those with known health conditions might also benefit from periodic exams. It's best to discuss your pet's specific needs with the veterinarian, as they can provide tailored advice based on your pet's age, breed, and health status.
