Smallest dog living

I have a cute Chihuahua dog called uru. He's extremely cute and he only weighed less than 2kgs, he is very tiny boy.
and this is a smallest dog in the world.....

 
The smallest dog living....is a long-haired, female Chihuahua called Boo Boo.
She's only palm sized... she doesn't look like a living thing but she is so cute!
but when I watched the video (I couldn't put the video here but you can watch it from the link below) , I was so worried that she would be stepped on by the big dog...
cause she measured 10.16 cm (4 in) tall on 12 May 2007 !!!!!!!!!!!!!!!!!!!!!!!!!!and is owned by Lana Elswick of Raceland, Kentucky, United States.
