The world’s smallest dog
He is a third of the size of an average guinea pig, and weighs in at just a few ounces – but this tiny puppy could be a big deal when it comes to world records.
The miniscule chihuahua-Jack Russell cross – appropriately named Tom Thumb by its owners – is a serious contender for the title of being the smallest dog on the planet.
Little Tom was born just three weeks ago as part of a surprise litter to mum Spice, a chihuahua.
And he is unlikely to get much bigger – with some previous experience of rearing puppies through their early weeks, the couple are convinced that Tom is almost fully grown now.
With his tan-and-black markings, Tom Thumb measures less than four inches from the tip of his nose to the end of his tail and only weighs about three ounces.

So cute — I like what the Jack Russell part has done to soften his face
