I can't believe Lurchers have only been mentioned once in seven pages of a food stealing thread! 
After rescuing our lovely boy, I left him for a few minutes in the kitchen diner with our collie/lab cross. Shrill barking from established dog brought me back in to an open bin, rubbish strewn into every corner and a very large, steaming poo.
I honestly don't know how he had time!
We installed a baby gate to the opening of the kitchen and stuck the bin in there. He can clear the gate effortlessly. We now have to put 2 chairs in front to stop him jumping.
Established dog is a telltale though... she has a special bark for, "Bracken's being bad." Although she was quite happy to share the enormous artisan garlic bread he pulled down off the top of the cooker...
If he's been up to no good while we're out, we always know because he hides himself under his blanket and pretends not to be there
.
For those who say he should be better trained. He came to us starving just 6 months ago. We can take his half finished food away and he will wait patiently for us to put it back. He won't start his meal until we say (pools of drool!) and will take food really gently from your hand if invited, but he won't touch if not.
He's just a bloody great opportunist if left unsupervised!
Oh, and he can open doors...
