zgirnius:
How about this...

He hangs about the garbage bins outside Honeydukes at night in dog 
form, and waits for a moment when there are no Dementors in sight. 
There isn't one posted permanently on every block, surely? The populace 
would never tolerate it. When the coast is clear, he quickly transforms 
and breaks into the cellar. (Does he have his knife that he gives Harry 
at this point?)
