Sirius and the Witch's Hump

The question here on this thread is "How was Sirious getting onto the 
Hogwarts' Grounds, and into the castle?'  One theory proposed was that 
he went via the tunnel through Honeydukes, although this raises the 
question of how he opened the Witch's Hump and how he got through the 
Honeydukes store. Another theory was that he used the tunnel from the 
Shrieking Shack.

I see a problem with the Shrieking Shack theory -- the Shrieking Shack 
is boarded up and sealed, presumably by Dumbledore.  Fred and George 
tried to get in, but couldn't.  I don't think Sirius could get into 
the Shack from Hogsmeade; the only way into the Shack is the tunnel 
from the Hogwarts' grounds. 

I think Sirius got onto the Hogwarts' grounds the same way he left 
Azkaban -- as a dog.  As far as the dementors are concerned, he'd be 
just one of many animals roaming around.  We do see him on the grounds 
as a dog, at least three times that I recall.

Now, how he gets into the Castle itself is another question.  But this 
is a problem for the "Shrieking Shack tunnel" theory, too.  Perhaps 
some of the kids have pet dogs and he enters the Castle as a dog, 
perhaps he sneaks in through some back door, I don't know.
