It’s harsh when you try to hide the food from your dog but he found your over-elaborated hiding spot in less that 10 minutes.
The same happened with the owner of this dog. He thought the dogs food will be safe in a so called “dog-proof” container.
Unfortunately for him, the dog figured out how to open the container in less than a minute, as you can see in the pictures below, and started eating the food for his stomach’s delight.
