Dogs may be "lesser beings" in terms of tool use, but certainly not in terms of feelings. The pics are chronological, so by #10 she'd become pretty discouraged. One thing she did that was clearly intended to communicate something, something completely unprecedented, was to go into an area of the house where some unused stuff is stacked up, crawl into an open space with nothing but her rear exposed, and bark her "do me" command bark. (She barks very rarely, but has several distinctive vocalizations, one of which means "no good" (like when throwing a too-small stick for her to retrieve), another of which means "attend to me" (usually more petting) like that one.)
The thing I noticed especially was the consistent positioning of her ears in these pics. They ordinarily rotate from straight forward and fully upright to fully flattened and the tip pointed backwards. The former means "fully positively engaged", the latter "very worried." The ear expression in these pics, a question mark(?), was very consistent and obviously meaningful to more to more sapient species than ours.
This is a more typical image of how she looks under normal circumstances, when all is well and her pack leader/sister/mother/best friend is present and engaged.
