Simon Cowell Warns Paparazzi -- My Dogs Will F U Up!

Simon Cowell is drawing a line in the sand ... paparazzi who want a piece of him will have to answer to his bitches.

Cowell's Yorkies -- Squiddly and Diddly -- aren't taking crap from the photogs who got their owner in trouble earlier in the week for allowing them on the beach in Miami.  Cops gave Simon a warning ... one which he clearly didn't heed.

But the pint-sized pooches seem to be doing the trick, scaring the bejeesus out of a papper.
