Bet she understands THIS hand signal
Angelyne the Amazing DEAF Cattle Dog (and her companion-person Eric Melvin) recently visited Boulder!
Yeah, more dogs. Angelyne allegedly knows 40-plus hand signals and "non-verbal commands" she will do tricks to, and Melvin hauls her around for such functions and activities as (according to Melvin's web page, feyly titled "A Unique Character and Compassion Development Presentation"):
From the Gamera's acknowledgement of Angelyne's recent visit, it appears most of her tricks involve Hula-Hoops. Almost makes me wish I were still an elementary school student, or even chronically or terminally ill (oh, I am, I just don't know it yet).
Actually the only reason I bring it up is that back when Billy Bob (another cattle dog) was a young'un, I taught him tricks (about eight of them, IIRC, the standard stuff--no Hula-Hoops) that he also would do from hand signals alone. And at the time, he wasn't even DEAF! The D-a-W and I used to gig (for free, natch) at coffee shops and housewarmings and the like (me on classassical git, her on that noted instrument of revolution, the Irish harp), and whenever possible I'd weasel BB in to do his stuff. Wowed 'em. At least, more than we did.
Update: Did you know that the Telegraph has a "Pets" page? It's a subcategory under "Families" which is a subcategory under "Lifestyles," and it's chock-full of cute-animal videos and stories ("Can my rabbit have a brace for its teeth?"; "Chihuahua foils armed robbery"), including this one: "Hitler cat 'overlooked for adoption because of markings.'" "Kitler" is cuuuuute (and I am emphatically not a cat person). Heil, Fancy Feast!
