How long can a dog be left home alone?

This is general information, not veterinary advice. If your dog is very distressed when you leave, or its behaviour changes suddenly, talk to your vet.

What the sources say about time alone

Three animal welfare organisations agree on the adult dog. The number quoted by a fourth source measures something different.

The RSPCA explains its four hours as giving the dog a chance to exercise, go to the toilet and spend time with people. PDSA adds that by then a dog may be hungry or need a toilet break. The American Kennel Club says even an adult dog should not be home alone much longer than six to eight hours without a chance to relieve itself. That is a ceiling for the bladder, not a welfare recommendation: a dog can hold on and still be bored or uneasy.

Four hours is advice, not law, and it assumes a dog that is already used to being alone.

What happens after two hours alone?

In a 2011 study by Rehn and Keeling, 12 dogs with no known separation problems were filmed at home while left alone for half an hour, two hours and four hours. There were no differences in behaviour during the separation, but there were when the owner came back. After two and four hours the dogs greeted more energetically, wagged their tails more, interacted more with the owner, and licked their lips and shook themselves more often than after half an hour. For heart rate the authors report only a tendency towards a higher rate, not a confirmed difference.

The sample is small and the study does not prove suffering. It does show that a dog does not treat time alone as neutral: already after two hours it behaves differently at reunion than after half an hour. Two hours and four hours alone are not the same number.

What decides how long your dog can cope

• Practice. PDSA and Dogs Trust stress that time alone should be built up gradually. A dog that has never practised may struggle even for an hour.
• The individual. The RSPCA and PDSA say four hours is a general figure, and the real limit depends on the dog's personality, routine and home.
• Breed. In the UK study by Dale and colleagues (2024, 145 puppies followed to six months), breed, sex and source showed no significant association with signs of separation-related behaviour. So do not assume a breed is independent by nature. How to pick a dog that fits your schedule is covered in How to choose a dog for your lifestyle.
• A change of routine. Harvey and colleagues (2022) followed 1,807 UK dogs during and after the first COVID lockdown. Dogs whose hours alone fell the most had a higher risk of new signs of separation-related behaviour. The share of dogs with signs dropped from 22.1% to 17.2%, yet 9.9% developed new signs. If you have been home for weeks, build absences back up gradually.

Puppies

A puppy's hours alone are limited by its bladder, and it is still learning to be alone. The AKC gives approximate bladder limits:

These are hours without urinating, not hours a puppy can spend alone without distress. Dogs Trust advises starting practice as early as possible because it best prevents problems later. In six-month-old puppies, Dale and colleagues (2024) found fewer signs of separation-related behaviour in those that were kept in an enclosed space overnight in their first 16 weeks and slept at least 9 hours. The authors stress the analysis was exploratory, so this is an observation, not proof.

How to teach a dog to be alone

Once a dog is happy to be left for up to an hour, the RSPCA says longer absences should not be a problem. Dale and colleagues (2024) also report that six-month-old puppies were six times more likely to show separation-related behaviour if owners responded to unwanted behaviour on their return by fussing over them. That too is an observation, not proof.

Signs your dog is struggling

• barking, howling or whining when you are gone;
• toileting indoors;
• destroying furniture, doors or windows;
• neighbours complaining about barking;
• the dog does not eat or play with toys when alone but does when you are home (Dogs Trust);
• hidden signs on video: trembling, pacing, whining (RSPCA).

The RSPCA cites research suggesting that eight out of ten dogs find it hard to cope when left alone, and half show no obvious signs. So, by the RSPCA's account, an undamaged home is not enough to show all is well. Dogs Trust warns that a dog shut in a crate or single room when you leave may be struggling with lack of choice rather than with being alone.

If you will be out for more than four hours

Dogs Trust advises arranging for someone to pop in or for the dog to go to doggy day care when you are out for longer. In our directory, 16 of 45 active pet hotel listings in Slovenia list day care and 11 list walks (as of 8 October 2026). In Croatia, 5 of 21 active listings list day care and one lists walks. Find the nearest in the pet hotel directory or the dog school directory. For the daily exercise a dog needs after time alone, see How much exercise does a dog need?. If you are still choosing a dog, how much time you will really be home matters too: read Adopting a dog or cat.

Frequently asked questions

Can a dog be left alone for eight hours while I am at work?

PDSA, RSPCA and Dogs Trust advise no more than about four hours at a time, so eight hours is beyond their guideline. Dogs Trust suggests that someone pops in during the day or that the dog goes to day care. If that is not possible, think about splitting the day, working from home or changing your lifestyle before getting a dog, not afterwards.

How long can a puppy be left alone?

The AKC says a puppy up to 10 weeks old can hold its bladder for about an hour, and from three months about one hour per month of age. That is a bladder limit, not the time a puppy can spend alone without distress. Start practice with a few minutes and build up gradually, as Dogs Trust advises.

Does my dog know how long I have been gone?

Rehn and Keeling (2011) could not tell, and wrote that their study cannot distinguish whether dogs are aware of the length of time alone. It did show that after two and four hours dogs behaved differently on reunion than after half an hour: a more energetic greeting, more contact with the owner and more signs of arousal.

Should I punish my dog if it destroyed things while I was out?

No. The RSPCA and Dogs Trust explain that a dog does not link punishment with something that happened hours earlier, and that anxiety grows before the next absence. According to the RSPCA, the look we read as guilt is often just a response to your anger. Shorter absences, a chew toy and professional help if the problem repeats work better.
