Table 1.
Demographic data of all 47 pugs included in the study.

Right lateral thoracic radiograph of a two-year-old male pug.
The green lines illustrate the measurement of the vertebral heart score (VHS), revealing a VHS of 11.4v in this subject.
Fig 2.
Right lateral thoracic radiograph of the same two-year-old male pug as in Fig 1, depicting the method for determining vertebral left atrial size (VLAS).
In this case, VLAS turned out to be 1.6v.

Measurement of radiographic left atrial dimension (RLAD) in a right lateral thoracic radiograph of the same two-year-old male pug as in Figs 1 and 2, being 1.3v in this subject.

Right laterolateral thoracic radiograph of a five-year-old female pug showing irregularly shaped and trapezoid thoracic vertebrae throughout the thoracic spine (marked with asterisks), leading to exclusion from radiographic measurements.

Right laterolateral thoracic radiograph of a four-year-old male pug with misshaped vertebral bodies from T4 to T8 (marked with asterisks), considerably influencing radiographic vertebral scores.
