How to Keep a Dog Entertained While You're at Work
A board-certified veterinary neurologist explains what a dog's brain actually needs during an eight-hour day alone, and how to build enrichment that holds up over months, not just the first week.
Keeping a dog entertained while you're at work starts with matching stimulation to what its brain actually needs.

The house I keep coming back to belonged to a 4-year-old Labrador mix named Gus, about 62 pounds, whose owners both worked hybrid schedules that had recently gone fully in-office. Within three weeks, Gus had pulled the stuffing out of a couch cushion, chewed through a baseboard near the front door, and started drinking water so fast after his owners got home that he vomited twice. Nothing about Gus’s bloodwork or orthopedic exam was abnormal. What had changed was the number of unstructured hours in his day, and nobody had replaced them with anything.
I open with Gus because his case is unremarkable, and that’s the point. In my practice I see this pattern constantly across breeds and ages: a dog who was fine on a slower schedule starts showing chewing, pacing, or house-soiling within two to four weeks of a household’s routine tightening up. The behavior looks disobedient. Neurologically, it’s closer to an unoccupied brain finding its own work, and usually not the work you’d choose for it.
What an Empty House Is Actually Asking of a Dog’s Brain
A dog’s brain doesn’t switch off between meals and walks. It stays online, scanning for novelty, scent, and social contact, and when none of that is available for six or eight hours, the drive doesn’t disappear — it gets redirected into whatever the environment offers, which in most houses means furniture, doors, and trash. This is the mechanism behind what looks like “boredom chewing”: a nervous system built to forage, track scent, and problem-solve for calories, given nothing to forage, track, or solve.
That framing matters before you buy a single toy, because it tells you what enrichment is actually for. It isn’t a distraction to burn ten minutes of energy. It’s a substitute occupation — something that recruits the same searching, chewing, and problem-solving circuitry the empty house would otherwise recruit on its own terms.
Sorting Real Enrichment From Simple Distraction
Not everything marketed as a dog toy does this job. The distinction I use with owners is whether an item requires sustained, effortful engagement or just occupies a dog’s mouth for a few minutes before it’s abandoned by the water bowl. Three criteria separate the two:
- Duration of engagement. A frozen, stuffed enrichment item typically holds a dog’s attention far longer than a squeaky toy tossed into a crate.
- Cognitive demand. Manipulating a puzzle to release food asks more of the brain than repetitive chewing on an inert object.
- Match to the individual dog. A frantic, food-motivated dog needs a harder puzzle than a mellow, easily-frustrated one; giving the wrong difficulty level to either produces frustration, not calm.
A guide from the American Veterinary Society of Animal Behavior recommends starting food puzzles at an easy difficulty and increasing challenge gradually, because a dog that can’t figure out a puzzle quickly enough tends to disengage or become anxious rather than mentally stimulated.
What the Evidence Actually Shows About Food-Based Enrichment
This is where I want to be precise rather than enthusiastic, because owners are often sold on enrichment in the abstract without knowing what’s actually been measured. A study published in PMC found that dogs given long-lasting chews during short periods of social isolation showed lower arousal and more positive emotional-state indicators than dogs given no enrichment or other food-based options tested in the same protocol. Separately, research in the JAVMA on environmental enrichment in shelter dogs found that enrichment additions changed measurable behavior, underscoring that this isn’t a soft, unfalsifiable idea — it shows up in observed behavior, not just owner impression.
What that evidence does not show is that a puzzle toy resolves true separation anxiety, and conflating the two is a mistake I see often. Ordinary under-stimulation and clinical separation-related behavior sit on a spectrum, but they don’t respond to the same interventions, and treating the second like the first usually just delays the dog getting help that actually fits.
When It Stops Being Boredom
Chewing on the couch corner because nothing else was on offer is different from a dog who begins drooling, trembling, or attempting to escape through a door within minutes of an owner leaving. Research on the PubMed: Aetiology of Separation-Related Behavior in Domestic Dogs has documented that separation-related behavior in dogs is a distinct, identifiable clinical presentation rather than simple mischief, with its own risk factors and its own trajectory if left unaddressed.
I had a Cavalier King Charles Spaniel in my practice, 6 years old, whose owner described a very specific tell: the dog began pacing and panting the moment she picked up her car keys, well before she reached the door. Puzzle toys hadn’t helped, because the trigger wasn’t the empty house itself — it was the anticipatory cue. Cases like hers are where I reach for both the diagnostic workup and the acupuncture needle: ruling out a medical driver of the anxiety with a real exam, then layering in a structured desensitization plan and, in dogs who tolerate it well, adjunct calming modalities alongside behavioral work rather than instead of it. The dog I’m describing didn’t improve because of a single tool. She improved because the anticipatory cue itself got retrained, slowly, over weeks — the puzzle toys came back into the plan only once that piece was addressed.
Building a Rotation That Actually Holds Up
A single puzzle toy loses its novelty within days for most dogs, which is the most common reason owners tell me enrichment “stopped working.” The fix isn’t a better toy. It’s rotation and variety across categories: a frozen food-stuffed item for the first hour alone when arousal from the owner’s departure is highest, a scattered-scent search for midday, and a chew appropriate to the dog’s size and jaw strength for the stretch before the owner gets home. Safe, dog-appropriate fillers matter here — our guide on whether dogs can eat sweet potato walks through safe prep and portions if you’re using cooked vegetables to stuff a puzzle rather than commercial paste.
Morning exercise changes how much of this a dog even needs. A dog who’s had an adequately tiring walk before you leave starts the alone-period with lower baseline arousal, which is a big part of why enrichment “works” for some dogs and seems to fail for others on an identical toy. If you’re unsure how much exercise is realistic for your dog’s age and build, our piece on how far a dog can walk or hike in a day is a useful starting point before you assume the puzzle toy is the problem.
Evening behavior is worth watching too, because a dog who can’t settle at night is often telling you something about how the day actually went, not just about the evening itself; our guide to why a dog won’t settle in the evening covers how daytime understimulation shows up hours later.
When to Loop In Your Veterinarian
If enrichment, exercise, and a consistent departure routine haven’t shifted the pattern within a few weeks, or if what you’re seeing includes panting, drooling, or attempts to escape rather than simple destruction, that’s a conversation for your veterinarian, not a bigger puzzle toy. A thorough workup should rule out pain, gastrointestinal discomfort, and cognitive change before anyone labels a dog’s behavior as purely behavioral — a mistake I still see made too often. Some owners are also managing a gut that’s under more stress than usual during this kind of transition, and it’s worth knowing that gut health and stress response are more linked than most people assume; our rundown of vet-reviewed probiotic picks explains what to look for on the label if your veterinarian raises that as part of the plan.
The Bottom Line
Gus, the Labrador mix from the opening, didn’t need a smarter toy. He needed a morning walk long enough to lower his baseline arousal, a frozen food puzzle for the first hour alone, and a scatter-feed session before dinner — a rotation, not a purchase. Most dogs left alone during a workday will respond to exactly that kind of structured, varied occupation for the brain. A smaller number are telling you something closer to a clinical picture, and that group deserves a real workup rather than a better toy. Knowing which one you’re looking at, and adjusting the plan as your dog’s routine or age changes, matters more over the next year than any single product decision does today.

Frequently asked questions
How long can I leave a dog alone with just a puzzle toy?
Most food-based enrichment items are designed to occupy a dog for the first hour or so after you leave, when arousal from your departure is highest, not the entire workday — plan on a rotation across the day rather than one toy lasting eight hours.
Do puzzle toys help with separation anxiety?
They help with ordinary understimulation, but true separation-related behavior is a distinct clinical presentation that generally needs a structured behavioral plan, and sometimes veterinary treatment, rather than a harder toy.
What's the easiest first enrichment item to try?
Start with an easy-difficulty food puzzle or a frozen stuffed chew before moving to scent-based scatter feeding, since a dog that can't solve a puzzle quickly tends to disengage rather than stay occupied.
