I don't know what you'll think about this, but this is pretty cool if you ask me:
"...two-legged Chihuahuas have been fitted with customized wheeled carts two assist with their mobility."
It's not every day you get to see people devoting so much energy and working so hard to improve the lives of living beings so small like this. It's a thing of beauty if you ask me.
