Leaving Your Pet Alone at Home: How Long Is Too Long?

Almost every pet owner leaves their animal alone at some point. For most households with full-time jobs, it is a daily reality. The question is not whether you can leave your pet alone — it is how to do it in a way that is safe and as stress-free as possible for the animal.

Dogs: Maximum Times by Age

These are general guidelines, not hard limits. Breed, temperament, and whether the dog has been gradually trained to tolerate alone time all affect this.

Puppies under 10 weeks: 1 hour maximum. Their bladder is tiny and they have no coping skills yet.
10–12 weeks: 2 hours
3–6 months: 3–4 hours
6–12 months: 4–5 hours
Adult dogs (1–8 years): 4–6 hours is the generally accepted maximum for a healthy, well-adjusted adult dog
Senior dogs (8+): Depends on health, bladder control, and mobility. Many older dogs need more frequent breaks.

Six hours is roughly the workable maximum for a typical adult dog. Beyond that, most dogs will be uncomfortable, some will be distressed, and bladder accidents become likely regardless of training.

Cats: More Flexible, But Still Needs Thought

Adult cats tolerate alone time much better than dogs. Most healthy adult cats can be left alone for a standard working day without significant stress, provided:

There is adequate food and water (automatic feeders and a large water bowl or fountain)
The litter box is clean at the start of the day
There is something to do — a window to watch from, a toy, a scratching post
They are not recently adopted (new cats should not be left alone for long periods while still adjusting)

Kittens under 6 months should not be left alone for more than 4 hours.

For multiple consecutive days alone (weekends away): cats can typically be checked on once a day by a sitter. Dogs cannot be left without someone visiting every 4–6 hours at most.

Signs Your Pet Is Not Managing Well Alone

Destructive behaviour that occurs only when you are out
Toileting accidents from an otherwise housetrained animal
Excessive vocalisation (neighbours reporting barking or howling)
Extreme greeting behaviour — frantic, prolonged, difficult to settle
Self-soothing behaviours: excessive licking, pacing, hiding on your return
Weight loss, reduced appetite, or increased stress-related shedding

These are signs of separation anxiety and are worth addressing rather than managing with longer leave periods.

Practical Preparation Before You Leave

For dogs:

A walk before you leave makes a real difference. A physically tired dog settles faster and stays calmer.
A puzzle feeder or stuffed Kong (frozen works best — slower to empty) gives them something to engage with.
Background noise — a radio or television — can help dogs who find complete silence stressful.
A consistent departure routine (put shoes on, pick up bag, say a calm goodbye) helps dogs predict what is happening rather than responding to unpredictable signals.

For cats:

Clean the litter box before you leave.
Ensure access to a window — watching the outside world is genuinely stimulating for cats.
Consider leaving a worn piece of clothing somewhere accessible. The familiar scent is reassuring.

Solutions for Long Working Days

If your schedule means your dog is regularly alone for longer than 5–6 hours, these options are worth considering:

Dog walker or midday visit: Even a 30-minute break makes a significant difference.
Doggy daycare: Works well for social dogs. Not ideal for anxious dogs or those who do not tolerate groups well.
A pet sitter: Particularly useful during disrupted schedules, holidays, or when your dog is unwell.

When using a sitter, having clear written instructions makes a real difference — especially for feeding schedules, medications, and anything specific the sitter needs to know.

Preparing Your Sitter

Whether it is a professional or a friend, a written handover document saves stress on both sides. Cover:

Feeding times, amounts, and food location
Walk routes and any dog-specific notes (reactive to other dogs, not to be let off lead, etc.)
Medications and how to give them
Emergency contacts: your number, your vet, and a backup contact
Any behaviour quirks or warning signs

A dedicated pet sitter instruction pack makes this straightforward to prepare and hand over.
