Have you ever asked yourself if dogs understand the concept of stealing?
In actuality, dogs don't fully grasp the term. In fact, they probably think it's just available food on a higher platform. Scavengers as they are, that's like being given a golden opportunity.
So if in case your dog does take food that's not supposed to be taken, here are some things you should consider doing.
1. Make sure that everybody is informed not to leave food lying around.
2. Correct the behavior. To do this, you might need to set-up a scenario in order for them to be corrected in a timely manner.
3. Make sure you are feeding your dog the right amount of food.
4. Don't just give him love, give him exercise and mental stimulation as well.
