Widget and Lyra actually get along quite well, but she tends to be way more vocal when she plays with him than when she plays with Sprite. And I do think Widget enjoys antagonizing Lyra a little. She's not always as noisy, but (Sprite excepted) if she's in one of our laps and another dog comes too close, she starts behaving as she did in the video. Snarly, snarly, toothy, toothy. What I really appreciate about her, though, is she's very careful to never actually connect. She turns her head away or lifts her chin, so she can snap and snarl without any nipping. And if you say 'Lyra, enough', she'll stop. But, oof, it is just too amusing to watch the dinkiest dog in the house strong arm everybody else.
