How many thoracic vertebrae does the domestic dog typically have?

Explanation:
The thoracic vertebrae are the vertebrae that bear the ribs, and in the domestic dog their number is typically fixed at thirteen, aligning with thirteen pairs of ribs. This fits the standard vertebral column pattern seen in dogs: seven cervical, thirteen thoracic, seven lumbar, three sacral, and a variable number of caudal vertebrae (usually around twenty to twenty-three). While occasional anatomical variation can occur, thirteen thoracic vertebrae is the usual count to memorize for dogs.
