Meet Disney, Britain's tiniest dog who stands at just 9.3cm (3 ins) tall and weighs 14 ounces (405g) and thinks she is a KITTEN - Pictured with 'best friend', five week old kitten Kiara. See NTI story NTIDOG. The pocket-sized chihuahua was part of a litter of three born on January 25 - but hasn't grown since she was eight-weeks-old. The tiny pooch is lighter than a bag of sugar and can be carried around by owner Natalie Vanes, 26, in the palm of her hand. Mum-of-one Natalie has to keep Disney away from her three other dogs at her home in Coseley, West Mids., in case they mistake her for a toy. As a result, Disney forged an inseparable bond with her pet kitten Kiera instead and they have been best friends ever since.
