In the first chapter of OOTP it says:
Harry had run barely a dozen steps when he reached them: Dudley was
curled on the ground, his arms clamped over his face; ...edited...
 
Now why would Dudley have his arms clamped over his face if he
couldn't see them?

Muggles can't see dementors.

Simple, Harry told Dudley to cover his mouth.

"DUDLEY, KEEP YOUR MOUTH SHUT! WHATEVER YOU DO, KEEP YOUR MOUTH SHUT!

moonmyyst objected: 
Since when has Dudley ever done anything, anything at all that Harry
said to do?  Especially if Dudley thought Harry was attacking him. 
Unless he saw the Dementors. I just find it very hard to believe that
if Dudley did not see them, then he would be thinking that it was
Harry doing the attacking, so why would he do what Harry told him to
do and help in the attack.

Carol responds:
But Harry also says, "DUDLEY, COME BACK! YOU'RE RUNNING RIGHT AT IT!"
(OoP Am. ed. 17). He wouldn't have to say that if Dudley could see
them. (Also, Dudley covered his bottom when he remembered the pig's
tail. Now he's covering his mouth, the part that's vulnerable now.
Surely he can tell from Harry's voice that he's deadly serious and he
does the only thing he can to defend himself.)

As I've said in other posts, JKR has repeatedly told us that Dudley is
a Muggle and there's no reason to doubt it now.
