Dumbledore warns the kids that dementors can't be fooled by tricks or disguises, or even invisibility cloaks. So neither of the kids' previous ways of sneaking about should work. He doesn't seem to know Animagi can escape them (of course he doesn't expect any Animagi but Minerva to be around). And in GOF Barty's story proves that they actually can be fooled by disguise.
While dementors can be fooled by at least 2 forms of disguise: Animagus transformation and Polyjuice (if the user is in similar mental condition as the one s/he is impersonating), we are introduced in this book to something that really cannot be fooled by any kind of disguise or invisibility cloak - the Marauders' Map. The only things that can fool it are people who have identical names and making places Unplottable. This is yet another thing that raises the question whether the Map is a Dark artifact (the answer depends on one's definition of Dark).
