Dementors and communication

I'm sorry if this has been discussed before, but how does 
Fudge/Umbridge communicate with the Dementors?  I've no doubt that 
if I tried to do it, I would pass out myself.  How do they manage 
it, I wonder?  Any theories?  For that matter, how would you tell 
two dementors, "I want you to go to Little Whinging and attack Harry 
Potter" ?  

I also ponder the question of whether or not Mundungus was set up so 
that Harry was left to defend himself when Mundungus was gone on h 
is "business opportunity".  If that's the case, someone knows MF is 
in league with DD - that would make MF a liability.  

Just sitting here pondering...
