I did a really quick supermarket run once, just, like, milk eggs and ice cream, or something, and there were rawhide bones on sale at the impulse buy counter near the checkout. So I grabbed a couple and stuffed them in my cargo pocket, since they didn't quite fit in the bag and I didn't want to waste getting another one... which of course put them at nose level when I walked in the door. My dogs watched me put them on the table and did not stop staring at them through the whole dinner-making process or the whole dinner-eating process. They took a short break to eat their own dinner then went right back to staring.
