we had a window cleaner come to our house when i was little and walked out leaving both the front door and gate open. the dog ran straight out and got hit by a truck. its not
always the owners fault! :wink:
the dog survived mind you but thats not the point lol
or they can dig out while you're at work during the day...sometimes its not so easily preventable
mind you i'm mostly on your side - for eg: there is really no reason for a cage door being left open etc. but its not always so black and white!
