No low-riders?

Teaching them to "shake" will probably be pretty challenging. "Roll over" too, I'd guess. But "play dead", with the wheels in the air, still spinning like in a just completed auto crash, should be awesome.

I, for one, welcome our tiny front-wheel drive overlords.

Very cool. But the article's "front-wheel drive" seems like a really poor description of this prosthesis.

They totally need to race these little guys.

Why are they born without front legs???

(By the way, speaking of paraplegic animals, our half-paralyzed mouse seems to be doing really well, considering. Goddamn tough little beastie.)

The article says a genetic mutation renders the little doggies armless.

How'd your mouse get paralyzed?

Don't try to understand them.

Cat Meals on wheels?

#7: Armless? I'd bet one o' them nippers'd rip your hand clean off if ye 'appened to give 'im 'alf a chance.

Also, how come we never get cool genetic mutations, like the X-men?

7: We don't know. Poor little mouse.

11: What do you mean "we", human?

we never get cool genetic mutations

Oh, it happens. For instance, I can turn beer into urine. Also, there's my freakishly large johnson.

Also, there's my...

You told me that was the doo-hickey you sold me. I got medical bills, you SOB.

Meddling humans have, by "helping", ruined the opportunity of these chihauhuas to learn to walk upright on their hind legs. Now they are chained for life to these wheels - and to elevated food/water dishes. Technology can only incompletely subsititute for a more caring interaction involving teaching.

Wonder whether they've taken to "marking" each others' wheels?

16: It's probably not too late to plead with them to have the chihuahuas shipped to you, Tom, for said more caring interaction.

17: That was firmly tongue-in-cheek M/tch.

Actually, the link indicates that these chihuahuas have also been trained in walking on their hind legs; the wheels give them an occasional break, in addition to satisfying some mechanically-inclined do-gooder.

FWIW, when my kids were growing up we got one nice yellow lab mix from the same shelter.

1: It seems they've traded off stability for turning ability.
