Toilet training- taking stage further after crate training

Question
Hi
I recently adopted a small terrier type adult dog from the dog pound. I have been toilet training her using a crate. At night she sleeps in the crate and during the day when we're at work I shut off half the kitchen for her. She's now great about not going to the loo in these places and about going when she is out on walks. The difficulty is in evenings and at the weekends when she is loose in the house with us. Then despite us taking her out every few hours she will still sometimes wee in the house but never in the kitchen where she sleeps. How can I teach her that she's not meant to go to the loo anywhere in the house? I think its a case of not holding it in rather than marking her territory as she'll do it in the middle of the room and in random places.
I have been trying to keep her close by me when I'm home so I can watch for signs she might need to go and quickly get her outside. The problem is she is also starting to get a bit overprotective of me and barking at other people if they approach me so I don't want to encourage her to be even more clingy.
Any ideas you have would be great
Thanks
Ruth

Answer
You are on the right track with keeping her close so you can quickly get her outside when she starts going inside. Keeping her in the crate for period of time during the day will help her learn to hold it as well. Make sure you do not leave food out all day, she can over eat or get bloat which is fatal and it does nothing for helping with toilet training. Whenever she eats or drinks try and take her out aout 30 minutes after to go potty. Make sure you clean up all accidents with a odor neutralizing pet stain remover and never clean them up in front of her.
Have strangers/friends/relatives give her treats and give her treats when people pass by so she learns to associate others with good things like tasty food.She will eventually stop her overprotective behavior if you are consistently praising her good behavior and giving her treats when new people are around.
