Why You Shouldn’t Leave Your Dog Alone for Long Hours

The key point first: There is no universal hour limit for leaving a dog alone—but there is a better question to ask, and it is more concrete than most people realize.

In Germany, the Animal Welfare Dog Ordinance (Tierschutz-Hundeverordnung) requires contact with the caregiver several times a day, for a sufficient length of time. For puppies up to twenty weeks of age, it requires at least four hours a day. And for dogs kept as the only dog, it explicitly calls for longer-lasting contact, several times a day. Rules elsewhere differ, but this is the explicit legal basis for the benchmark used in this guide.

So the question isn't "how many hours can I be gone?" but: How often each day does my dog get real contact? Eight hours in a row is something different from two stretches of four with contact in between.

The rules—and what they can't tell you

In Germany, § 2(1) of the Animal Welfare Dog Ordinance requires that a dog be given sufficient exercise outdoors, contact with its caregiver several times a day for a sufficient length of time, and regular contact with other dogs. Exercise and social contact must be adapted to the dog’s breed, age, and health. § 2(3) adds that a dog kept on its own must have the opportunity for longer-lasting contact with caregivers several times a day.

A rule that is often quoted—at least one hour of exercise a day, split into at least two walks—was planned in the original draft of the revised ordinance but did not make it into the version in force. Outside Germany, animal welfare laws or local regulations may set different requirements; check which rules apply in your area.

Whatever they say, a fixed number rarely answers the question for your dog. "Enough" exercise and "enough" contact have to be measured against the individual dog—its breed, age, and health. That is less precise than an hour count, but in substance more demanding.

How to tell whether your dog is coping

This is where many guides have a practical gap: they list symptoms you can't even see.

A recording tells you the most. Set up a camera or an old smartphone and record the first thirty to sixty minutes after you leave. In practice, many separation-related problems already show up in this window—after that, some dogs settle down out of exhaustion. If you simply come home and find everything intact, you haven't checked anything.

What to look for in the recording: panting without heat or exertion, pacing, staring at the door, drooling, whining or barking in waves, scratching at exits, repeatedly getting up and lying down again.

And one point that is often overlooked: a dog lying quietly is not automatically relaxed. Some dogs freeze instead of becoming active. Pay attention to body posture—a dog sleeping in a relaxed way lies differently from one lying awake and watching the door.

Separation stress, separation anxiety—and what else may be behind it

Distinguishing between milder stress and pronounced panic is useful. But another distinction matters more: not every problem with being alone is fear.

That is why behavioral medicine uses the umbrella term separation-related problems. Very different causes can lie behind them:

• Fear or panic about being alone itself
• Frustration—the dog wants to follow, not because it is afraid but because it wants to come along
• Noise fear that happens to occur while nobody is home—the dog doesn't have a separation problem but a fireworks or construction-noise problem
• Too little stimulation or boredom, especially in adolescent dogs
• Physical causes—pain, bladder problems, and in seniors, cognitive changes

This distinction isn't hair-splitting: the training differs considerably. A frustrated dog needs something different from a panicking one.

Especially important if it starts suddenly: if a dog that stayed alone without problems for years suddenly starts having difficulties, a veterinary checkup comes first. Pain and age-related changes can also show up as a dog no longer being able to let its person leave.

Being alone has to be learned

Staying alone is not innate behavior for dogs. Ideally, getting used to it starts early, but adult dogs learn it too—more slowly and with more patience.

You build it up in steps that your dog can still handle in a relaxed way. In practice, that means seconds at first, not minutes. And the duration is not increased in a straight line but varied—sometimes longer, then shorter again—so that absences don't predictably keep getting worse.

A common training mistake is going by the clock instead of by the dog. If you come back and your dog was restless, the step was too big—so the next one gets smaller, not the same size.

What helps in everyday life

Before you leave, a walk, a calm training session, or some time together. Not meant to tire the dog out—an overexcited dog relaxes less well than a balanced one.

A fixed retreat that your dog seeks out on its own and where it is left undisturbed.

Chewing and sniffing have a calming effect on many dogs because they engage natural behaviors. Food-dispensing toys, lick mats, and snuffle mats are well suited to this.

Two caveats that are rarely mentioned: a dog with pronounced separation anxiety often doesn't eat at all as soon as you're gone—in that case, a full Kong says nothing about how the dog is doing, only that it couldn't eat. And if you give the food toy every time right before you leave, it can become a signal that announces the separation and trigger tension in its own right. Give it when you stay home, too.

What doesn't help: scolding when you get back. The dog can hardly connect this with what happened hours earlier—more likely with your arrival, which can then become stressful in itself.

When you're gone for longer

If your dog regularly has to stay alone for many hours, additional care is part of the deal.

A dog sitter or a dog walker who comes by in between—often the least complicated solution, because it splits the day.

Doggy daycare can offer structure, exercise, and social contact. It doesn't suit every dog, though: for insecure dogs or dogs that don't get along well with others, a group is additional stress, not a balance. Pay attention to group size, places to retreat, and whether there are real rest periods.

People you know—even short visits break up the day effectively.

What matters is that your dog isn't just being stored somewhere. Two hours of group care without a chance to retreat can be more exhausting than two hours alone at home.

Conclusion

The honest answer to "how long can I be gone?" is: it depends—on the individual dog.

What can be said: the German ordinance sets contact several times a day as the benchmark, not a number of hours. For puppies up to twenty weeks, it requires considerably more. And you only know whether your dog is really coping once you have recorded it.

The rest is training in small steps—and the willingness to take a step back when one was too big.

A note on the sources

The legal information reflects § 2 of the German Animal Welfare Dog Ordinance and does not replace legal advice. The widely repeated rule of at least one hour of exercise a day comes from a draft of the revised ordinance that did not enter into force in that form (Schwarzer & Erhard, 2023).

There is no universally agreed maximum for how long adult dogs may be left alone; the circulating rules of thumb of four to six hours are recommendations without a consistent data basis, which is why we don't give a number here.

The recommendations on building up training, video observation, and distinguishing the underlying motivations follow practice in behavioral medicine. Comparative intervention studies that test individual approaches against each other are only available to a limited extent for family dogs.
