i have two kids and two dogs so i feel ya.  we have no rug in our dining room for that roeasn- too many have been ruined along the way.  well sunday night our dogs were in the living room (we only allow them in there when we are home) when charlie decided to pee on my gray west elm zabra rug... and there is no overhead light in there, only a lamp.  so i tried to clean it with oxy.  i woke monday morning to see just how bad it really looked.  :(
