The Question
“Hi Dr Paola,
Luna is a 7-year-old female Husky-Lab mix. She likes to break into lunchboxes, somehow finding them on shelves, the table, or the counter, and then opens them without destroying them. Is it that she’s bored or hungry? She recently had a check-up and was told 38kg is overweight, so I started feeding her separately and giving her fewer treats.
Thanks,
Julie”
Quick Info about Luna
Dear Julie,
Luna's behavior is much more likely to be driven by opportunity and natural food-seeking instincts than by hunger alone. Many dogs, especially breeds like Huskies and Labrador Retrievers, are remarkably skilled at finding food and remembering where it has been stored. Think of it like someone who always notices a cookie jar on the counter. Even after a meal, the temptation is still there. The fact that Luna carefully opens lunchboxes without damaging them suggests she has learned that this strategy is rewarding, and each successful "treasure hunt" reinforces the habit.
This type of behavior is what trainers call ‘self-reinforcing’. Every time Luna successfully finds food in a lunchbox, she rewards herself without any involvement from people. Food is a very powerful reinforcer, so even if she only succeeds occasionally, those successes are often enough to keep her searching. It works much like playing a slot machine. An occasional payoff can make the behavior surprisingly persistent. This is why counter-surfing and food stealing can become so well established over time if dogs continue to find edible rewards.
Since her recent examination identified her as overweight, reducing treats and managing her calorie intake is an appropriate step, as long as her daily diet remains complete and balanced. Most overweight dogs are not truly hungry. Instead, they are motivated by the rewarding nature of food and the expectation that searching may pay off. Feeding her separately is perfectly reasonable if it helps prevent her from accessing another pet's meal, but it will not necessarily change her habit of looking for unattended food around the house.
The most effective approach combines management with enrichment and training. Keeping lunchboxes and other food securely out of reach prevents Luna from rewarding herself, which is an essential part of breaking the cycle. At the same time, providing food puzzles, scent games, and regular training sessions gives her an appropriate outlet for her natural foraging instincts. Regular exercise, tailored to her age and fitness level, will also support her weight-loss plan while helping meet the physical and mental needs of her Husky and Labrador heritage. Over time, if the opportunity to self-reward disappears and appropriate activities become more rewarding, the behavior often becomes much less frequent.
I hope this helps!
