Yes Weasels, you are right about commitment, a dingo is not a dog you can just leave alone in the back yard. Their mind is always active and they are always trying to think of some crafty or cunning trick to play on you. :D Zara has the run of the yard and house and there is almost always someone at home to keep an eye on her.....My Yorkie comes dobbing on her if she breaks any rules, like getting on the lounge or beds etc. Zara understands quite quickly what is expected of her, but still likes to bend the rules. They are not a dog you could or in my opinion should try to "crate train" confinement goes against their wild side.
If we do have to leave her alone for a couple of hours here or there we have constructed a large enclosed area for her, we learned that nothing else would keep her in the yard. While we are home she never tries to get out, but as soon as we went out she would quickly devise a way to escape the rear yard no matter what we tried, once out she would not go anywhere just sleep on the front patio, It was enough for her to prove she had outsmarted us again.
