Evolution Made Them Do It

Dogs are opportunistic scavengers by design. For thousands of years before they shared our kitchens, survival meant eating whatever food turned up, wherever it turned up.

Counter surfing is a self-reinforcing habit. The instant your dog scores food, the behavior is paid off — and the payoff is the food itself, not your reaction. That is why scolding afterward does nothing: the reward already happened. Every successful raid makes the next attempt more likely, whether you punish it or not.
