Your post had me in fits of giggles at the way you wrote it.
She looks like a Chi to me, albeit a very wicked one
Darn it, all my years I've put up with my furniture being chewed down below by dogs & up above by parrots - who ever would've thought of putting legs in buckets like that, what a fantastic idea. Unfortunately one of my Chi's prefers door frames to anything else, bless him.
As for biting, snapping & snarling - I don't hold with this mamby-pambyview of not disciplining little dogs "because it scares/traumatises them, makes matters worse etc" - I make no allowance for my guys' size (except my Tiny). To me a dog is a damn dog, and will behave as such. Just lucky for mine they'll all perfectly behaved, loving, super eager to please & responsive, except in the area of toileting STILL, grrrrr.
Actually, come to think of it, my little girl went for my 12yo son's face a couple of days after she came - he awoke her from a deep sleep. No allowances .... she got her bottom firmly walloped once accompanied by very loud, strong and angry growling "No! Naughty Girl, grrrrr. No!!!" and put straight in another room. She's never even as much as curled her lip since, and adores everyone, especially me, the walloper/growler. Mind you it doesn't work with every dog and can exacerbate the problem IF they don't see you as Lead of The Pack/Boss Cocky..
