I also use the pads from piddlepad.com.  They are wonderful!  I have several different sizes for different locations in the house.  I ordered some the huge ones (30' x 36') for my kitchen because that's the main place my two usually go but I also have one in my bedroom.  I put 2 down in my kitchen (in different spots) and the 1 in my bedroom.  My Maltese is a real wizzer and tends to go a lot.  Muffin has little silver dollar size pees but Biscuit the Maltese has to 'trump' Muffin's pees every time she goes.  Talk about a pissing contest..... But I never have to change the pads more than once each day.  I have quite a collection of these pads so I only have to wash them like every 3 days or so.  The soiled ones go out in the garage in a bag until I wash them.     
I've never had problems with leakage.  These pads are thick and so, so sturdy.  They will last through hundreds of washing.  I was them with laundry soap and add a little Oxy Clean for good measure.     |
