Your Dog Knows To Steal Food When Nobody's Watching

In my experience dogs definitely do have this kind of cognition. I had a dog that I'm sure was an outlier, but was basically a super genius.

List of tricks she pulled:
1. knocked on back door. pretend to go half in. waited for other dog. went back for other dogs rawhide.
2. rattle open cage door and yowled like hurt. waited for master and other dog. verified other dogs arrival. went and stole rawhide
3. liked to go out many times in winter to check the temperature. had to throw up one day and was rushed outside. was refused to go outside after the first time by tired masters. started pretending to throw up in order to be let outside. masters caught on and stopped letting out. got frustrated a few weeks later and forced real throw up. masters then always let her out. Never pretended to throw up again.
4. had owner fussing over blanket on dog sleeping chair (to prevent hair build up on chair). decided not to bother owner and would straight out blanket by themselves. attempted to put blanket on back of chair by standing up on chair, leaning front paws in standing position, but couldn't figure out how to get blanket past front paws. gave up on full blanket straighten and just straightened it on the seat from then on.
5. looked both ways when crossing street.

I'd like to say this was a lassie type border collie and could be trained to do amazing things, but it was a basset hound.... never even learned to come on command

6. (would only come if she wanted to... needed a massage, was offered a treat.... etc.

^same with cats...

once cought mine sniffing in the trash can, when i came into the kitchen, she saw me went on to the chair, layed down, closed her eyes like she was sleeping then opened just one eye to see what will i do ^^

every animal has its own personality (who owned a dog or cat or whatever knows what i am talking about)

absolutely confirmed on cats.

I have a cat that actually knows what revenge is (or at least i'm pretty sure she does) If you don't let her into your room at night she simply go to kitchen, open the cabinet door, and dump the contents of the trash can on the floor. She also is deliberately spiteful. It has been witnessed that when she was told not to jump on a dresser, she acknowledged the person, proceeded to jump on dresser, and then proceed to walk over to the jewelry on the dresser, looked at the owner, and the proceeded to push it off onto the floor, and then walked away.

you know that cat meat is ediable right?

Watch Dog whisperer
By dog morality, that food wasn't owned.
only food inside your personal space belongs to you, if they break their own laws, chastise, otherwise ease up.
