This is Posy - a beautiful Yorkshire Terrier dog.

Isn't she cute?

Stephen's holding her collar here, and as you can see, it's very tiny!

But which dog do you think the other collar belongs to?
The answer is a Bull Mastiff!

This chap's an Old English Mastiff and he's very, very large!
Posy is only 20cm high.

The smallest dog ever was also a Yorkshire Terrier - only 7cm high!
Old English Mastiffs are the biggest dogs in the world and when fully grown they can be up to a metre in height and up to 104kg in weight.

That's the same as 500 cans of beans or 76 times as heavy as Posy!
So - one little, one large.

But both equally Brilliant Creatures.
