Distribution of signalment and clinical variables in 550 pugs with a normal and an abnormal gait. Pugs with an abnormal gait included all pugs perceived by their owners to have a gait abnormality, and all pugs that were reported to wear down their nails and/or the skin on the dorsum of their paws independent of their owner’s perception of the gait. Note that there was a possibility for the owner to include more than one answer or provide no response to a specific question, which is the reason why the numbers in each column may not add up to the total in the adjacent column
