Layla is 100% potty trained. i kept her crate (where she slept at night) small... i packed towels in the back to limit her space so that she could only stand up and turn around. Also she uses a bell. it is hung on the front door and i would ring it every time we went out, and now she knows to ring it. It works great for us because when i'm in the family room i can't see the door but i can hear the bell
they are tough to train but it is possible to have a dog that is 100% trained. just keep in mind, Layla is 18 months and will STILL pee a bit if she gets overly excited... that isn't the same as having an accident... if we are going to have company or another dog is going to come over. we meet outside so her piddle happens out there. you can't get mad if he does that... because he isnt' even aware he is peeing
