I have never heard of WizDog.  I use piddle pads for both of my boys and I think they are wonderful.  I take them when I travel or go visiting relatives and the boys use them. I also use belly bands to prevent accidents depending on where and who I'm visiting.  Neigher of my boys like
wearing belly bands, so they are happy to potty on piddle pads.  NOW, sometimes the baby (1yr 4months) will have an accident and most of the time it's my fault for not watching him and reminding him to potty on his piddle pad.  I love the idea of the bread tray!!  Wonder where I can get one of those????  Hmmmmmm  I can't wait to try that!  GOOD LUCK!  If I find a bread tray I will let ya know how the "bread tray" training goes.
