Sherlocks Tiny Companion

Mycroft comes bearing a gift, much to Sherlock's dismay. He doesn't want it, but there's no choice in the matter. He comes into possession of a puppy that was bred for military work, but was put out of commission. The last thing Sherlock wanted was a flatmate, but at least little John Watson can't speak. Instead, he is annoyingly expressive and follows Sherlock everywhere! Not only that, Sherlock has to deal with annoying Yarders, an even more than annoying brother, a really snaky and over intelligent puppy and cases. Before the end of the day, Sherlock is pretty sure he is going to lose it.
