The thing is, the pug really is supposed to be a bulldog.

In fact, Merlin had already picked out a breeder and was on his way to pick up the pup when he decided to drop off some supplies at the shop. It's as he's walking back to his car that he hears the whimpering.

The noise – a high-pitched and rather annoying, to be quite honest, whine – is coming from a small box left on the street in an alley, and when he pushes open the flaps, he finds himself staring a dirty baby pug. It's small and shaking and when he moves to pick it up, it chomps down on his hand with more force than expected, which would have been menacing if not for the barely developed nubs it has for teeth.

It's the most pathetic thing Merlin has ever seen.

And yet, there's something familiar about how scrappy it is, how it lets out the tiniest of growls, how it tries to squirm out of his grip when he picks it up. The next thing he knows, he's driving away with the pug in the passenger seat.

It's not until he presents the puppies to the recruits that he realizes who it reminds him of. And Merlin has to stifle his laughter when he hears Eggsy ask if it'll get bigger.

It's not a bulldog, but it's a perfect match.
