Sherlock gets a "stupid" dog*. Make it a "manly" dog. Big and fluffy and absolutely fierce looking but actually completely and utterly adorable.
The dog is very playful and overly eager to please its master and will follow Sherlock around EVERYWHERE.
John is surprised at how affectionate Sherlock is with the dog (who in turn is overly affectionate back) and how much Sherlock spoils it. Especially when Sherlock comments fondly that his new dog reminds him of Anderson. lol
*stupid dog - not truly stupid, just appears so. The dog just doesn't give a fuck about anyone else and will not follow simple orders because they are not worthy. Sherlock doesn't give orders/doesn't bother with training the dog to do tricks because that's just beneath them both. The dog will do anything Sherlock says if Sherlock gives orders.
