Auhor's Note: This is my story for December 1st. It's based upon I'm Nova's prompt, "John's bullpup". First person to find the hidden Lestrade cameo gets to appear as a guest in a future story!
Bullpup
"Really, Watson, how long are you going to sulk?"
Watson gave no reply. He crossed his legs in front of him, remaining seated in his armchair in the living room of 221B Baker Street.
"Watson, please, come on... I needed to test it."
Again, Watson said nothing. He picked up a broadsheet newspaper from the arm of the chair, and raised it in front of his face, blocking Holmes from his view.
"Watson! Listen to me, Watson! This 'Sweeney Todd' character is no laughing matter!"
Watson's hands clenched involuntarily, ripping the newspaper. His eyes bulged angrily from his face, and his cheeks began to redden. His jowels started to shudder, and Holmes started to worry in earnest.
"Listen here, Holmes!" Watson ejaculated. "This is a step too far! 'Sweeney Todd' is nothing but a character from a penny dreadful. You know as well as I that your damned experiment had nothing to do with solving crime."
"Watson, I assure you-"
"SILENCE! NOT ANOTHER WORD!"
Watson leapt from his chair, throwing aside his newspaper as he did so, and then stalked to the corner of the living room. Here, he stood over a large basket, pointing at it and shaking his head.
"This bullpup is all the family I have in this world, Holmes, and you... and you..."
He could not talk any more, so he merely pointed at the dog. Holmes gulped.
"I am sorry Watson, truly, I am. I failed to realise how important he was to you. I will make this right - I will."
The bullpup was in perfect health, of course; Holmes knew better than to hurt Watson's precious pet. The dog's jowels were as animated as Watson's own - Holmes noted this to himself with a satisfying feeling of cruelty - and its tail wobbled merrily to and fro.
Unfortunately, Holmes had failed to anticipate Watson's feelings about the bulldog's new, poodle-inspired haircut.
