Britain’s tiniest dog Disney stands just three inches tall and is so small she thinks she is a KITTEN.

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 weighs just 14oz (405g) – 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 Natalie’s pet kitten Kiera instead and they have been best friends ever since.

Disney plays with kitten toys – as the dog toys are too big for her – and even pinches Kiera’s food out of her bowl.

The pair also sleep together on a heat-mat in a special dog crate, which is kept in Natalie’s bedroom, and can fit in a plant-pot together.

Disney only weighs the same weight of a five-week-old average Chihuahua, which currently makes her the smallest dog in Britain.

The 14-week-old pup is on course to break a Guinness World Record for the smallest dog if she continues to grow at the same rate.

Natalie, who lives with fiance Stephen, 30, and their five-year-old daughter Summer, said: “Disney was a normal sized little puppy and was fed and reared by her mum Tinkerbell and didn’t really need any special treatment.

“As time passed they both grew normally but they were quite small. However, their mum and dad are small so I wasn’t too concerned.

“Since then her brother has grown into a lovely boy weighing 800g at 12 weeks but Disney only weighed 380g at 12 weeks.

“That’s when I realised how small she actually was.

“The unique thing about Disney is that she has never really grown since eight weeks old. She is a normal healthy fun little puppy, full of energy – just so tiny.”

“I have to be careful when I take her out, I wrap her in a blanket as she gets cold and no collar is big enough to fit her.

“She became best friends with Kiara as we needed to keep away from the other dogs in case she got squashed.

“They soon became inseparable and would be by each other’s side all the time. Disney plays with the tiny fluffy mice toys as dog toys are too big and heavy for her.

“She also enjoyed stealing Kiera’s food, she thought she was a kitten and they snuggle up together as well.”

The current smallest dog in the UK is Tyson – a four inch Lhasa Apso cross Chihuahua who lives in Lincoln with owner Rosemarie McLinden.

The world’s smallest living dog is a female Chihuahua called Miracle Milly, who is 3.8in tall and weighs 1lb.

She sleeps in a doll’s crib at her owner’s home in Dorado, Puerto Rico.
