¹PSS (Pain severity score), Arithmetic mean of four questions rating the dog’s pain intensity in the last 7 d.

²PIS (Pain interference score), Arithmetic mean of six questions rating how much the dog’s pain interferes with its normal activity.

^a,

^bWithin a row, means with different superscripts differ (P < 0.05).
