He's a Yorkshire terrier and measures a cute 13.97 centimetres. But he's only three months old!
Which means he's just a quarter of the size of a normal Yorkie terrier.
His owner Marjorie Pearce, a dog breeder, hopes he will grow a little bit more - at least twice the size he is now.
But she has to hide him under her coat when she takes him out for walkies because he's such a hit with the locals, everyone wants to hold the wee fella.
Both Dylan and Taz are still giants though compared to the world's smallest dog which was a Dwarf Terrier measuring a miniscule 7.1 centimetres!
