How Long Can You Leave a Dog Alone? Guidelines by Age and Breed

This is one of the most common questions from new dog owners — and one with real welfare implications. Dogs are highly social animals that evolved alongside humans. Left alone for too long, too often, they develop stress, anxiety and problem behaviours. Here are the actual guidelines.

General Guidelines by Age

Puppies Under 6 Months

Maximum: 1 hour per month of age (so 8 weeks = 2 hours max).

Puppies can't hold their bladder for long, panic easily when alone, and need constant stimulation and socialisation during their critical developmental window. Never leave a puppy alone all day from day one.

Adolescents (6–18 months)

Maximum: 4 hours gradually, building up over weeks.

Physical capacity improves but adolescence brings frustration, energy and sometimes an increase in separation-related behaviour. This is when separation anxiety often first manifests or worsens.

Adult Dogs (18 months–7 years)

Guideline: up to 4–6 hours as a general rule; 8 hours as an absolute maximum in exceptional circumstances.

Many working owners routinely leave dogs 8 hours — dogs adapt but this is near the ceiling of what's reasonable. A dog left alone 10+ hours daily is at significant welfare risk: toilet accidents, frustration-based destruction, and chronic stress are common.

Senior Dogs (7+ years)

Return to shorter alone times — similar to adolescents, often 4–5 hours max.

Older dogs may develop cognitive dysfunction (canine dementia), incontinence, or joint pain that makes being alone more distressing. Senior dogs also sleep more but may be more anxious when awake.

What Counts as "Alone"

A dog with another dog is not fully alone — this is a significant welfare difference. A dog with a cat: still essentially alone emotionally. A dog with a person other than the primary owner: depends on relationship.

Signs Your Dog Is Struggling with Alone Time

• Toileting indoors (not due to medical cause)
• Destruction focused around exits (doors, windows)
• Excessive barking or howling reported by neighbours
• Over-the-top greeting when you return (beyond breed-normal)
• Panting, drooling, or pacing at departure signals
• Not eating while alone (visible on camera)

Practical Solutions for Long Work Days

• Dog walker or midday visit: A 30-minute walk halfway through the day makes 8 hours manageable for many adult dogs.
• Doggy daycare: Ideal for sociable dogs, expensive but effective. Not suitable for anxious or dog-reactive dogs.
• A second dog: Works well for the right pair — but introduces complexity and two sets of needs.
• Camera monitoring: Lets you assess the reality. Many owners are surprised by what they see (and don't see).
• Mental enrichment before leaving: A morning training session and a frozen Kong on departure cuts anxiety significantly.

Building Alone Tolerance

If your dog struggles with alone time, systematic desensitisation — starting with 30-second absences and building very gradually — is the evidence-based approach. Log your dog's progress in Purzi: what duration they tolerated, what behaviours appeared, how they greeted you on return.
