2011 Chevrolet Suburban LTZ AC leaking on Passenger Floorboard Under Floor Mat

We have working dogs so our vehicle AC runs a lot while the vehicle is
parked.  The passenger floorboard gets soaked with water (yes, confirmed
not antifreeze) underneath the floor mat (nothing on top).  Doesn't have to be
raining or wet so believed to be related to AC.  Only in the middle  of the
passenger side floorboard and back underneath the passenger seat.  Have
pulled the carpet and mat but can find no hoses in the area which may be
clogged or leaking.  Ideas on possible source?  For good measure sealed
drain plug in floor board, as suspected, coming from within the passenger
compartment.  Underneath the console is dry, carpet inside of rocker panel is
dry.
