Miley moved into her former, and possibly current fiance's Malibu home last week and we've learned she brought her four dogs along.
They now have SIX DOGS between them ... not counting Miley's other pets.
The two aren't without help -- Liam has a couple of extra hands who live with him and they're all sharing in doggie responsibilities.
Miley may be cashing in on a debt, because she watched one of Liam's dogs a couple months ago while he was away.
Miley Cyrus ... Must Love Dogs.
