The wording given to the owners is all presented here, and in the supplementary material. No further definitions for behaviours or vocalisations were given. Pined, whined and cried were all mentioned, as all are words owner tend to use to describe similar dog vocalisations. As with all owner awareness of SRBs, it is fundamentally challenging unless they use recording equipment to view their dogs when they leave them or are otherwise able to view their dogs when alone such as by looking through a window. As this is a limitation of the method used, the appropriate place to mention this would be in the Discussion, not the Methods, so we have not discussed this limitation there.
This is a great figure, thank you for including it.
