September 26, 2025 |

Dogs are sociable animals and love company. But as much as we might want to, we can’t always spend every moment together. After all, what happens when you go on holiday or need to travel for work? In this blog we’ll be answering the popular question: can you leave a dog alone overnight? Keep reading for our advice!

Leaving your furry friend home alone overnight can be stressful – both for you and your pup! As a dog owner myself I’ve definitely experienced that pang of guilt when I need to leave my dog by himself for extended periods. But sometimes life happens – maybe you’ve got an emergency a work trip, or even just a night away that can’t include your four-legged buddy.

So, can a dog be left alone overnight? The short answer is it depends on your individual dog’s age, health, temperament and training level For many adult dogs, spending one night alone with proper preparation is usually okay. However, puppies, elderly dogs, or those with health issues or separation anxiety might need alternative arrangements.

Let’s dig into everything you need to know about leaving your dog alone overnight and how to make it a safe, comfortable experience for your pup.

Factors to Consider Before Leaving Your Dog Alone Overnight

Before you decide to leave your pup alone for the night, consider these important factors:

1. Your Dog’s Age Matters

Different ages have different needs:

  • Puppies (under 6 months): Generally shouldn’t be left alone overnight. They can’t hold their bladder for long periods and need frequent potty breaks.
  • Adult dogs (1-7 years): Most can handle overnight periods alone if properly prepared.
  • Senior dogs (8+ years): May have medical conditions or mobility issues that require more frequent care.

According to HoundGames, there’s a simple formula for how long puppies can hold their bladder: their age in months plus one. So a 3-month-old puppy can typically only hold it for about 4 hours.

2. Your Dog’s Temperament and History

Some dogs are naturally more independent, while others become anxious when left alone. If your dog has any of these behaviors when you’re gone, they might have separation anxiety:

  • Excessive barking or howling
  • Destructive chewing or digging
  • Indoor accidents despite being house-trained
  • Pacing, drooling, or panting heavily
  • Attempting to escape their environment

Dogs with severe separation anxiety should not be left alone overnight. It’s stressful for them and potentially dangerous.

3. Health Considerations

If your dog has any health conditions that require medication on a schedule, needs frequent potty breaks, or has mobility issues, leaving them alone overnight could pose serious risks.

4. Previous Experience Being Alone

Has your dog been left alone for extended periods before? If not, jumping straight to an overnight absence is probably not a good idea. You’ll want to gradually build up their tolerance to being alone.

How to Prepare Your Dog for an Overnight Stay Alone

If you’ve determined your dog can safely spend the night alone, here’s how to set them up for success:

1. Create a Safe, Comfortable Space

Rather than giving your dog free reign of the house (especially for first-time overnight stays), consider setting up a playpen or dedicated dog-proofed room with:

  • Their bed or crate
  • Water (in multiple bowls in case one spills)
  • A few favorite toys
  • Appropriate potty area if needed (for puppies or senior dogs)

2. Tire Them Out Before You Leave

A tired dog is generally a better-behaved dog. Before you leave:

  • Take them for a long walk
  • Have an extended play session
  • Do some mental stimulation activities

As HoundGames mentions, “Before you leave, spend time with them burning off energy. Go into the yard for a runaround. Be sure to also spend at least a few minutes on training, as this will tire out their mind as well.”

3. Provide Engaging Entertainment

Boredom can lead to destructive behavior. To keep your pup occupied:

  • Leave puzzle toys filled with treats
  • Provide durable chew toys
  • Consider leaving on some background noise (TV or radio)
  • Rotate toys to keep things interesting

4. Set Up a Potty Solution if Needed

For puppies or dogs that can’t hold it all night:

  • Set up potty pads in a designated area
  • Consider a dog door to a secure yard (for trained dogs)
  • Arrange for someone to come by for a late-night potty break

5. Practice Departures Without Fanfare

Make your departure calm and casual. Don’t make a big emotional scene which can actually increase your dog’s anxiety.

6. Consider Remote Monitoring

Pet cameras that let you check in and even dispense treats can give you peace of mind when you’re away.

Alternatives to Leaving Your Dog Alone Overnight

If you’ve determined your dog shouldn’t be left alone overnight, there are several alternatives:

1. Hire a Pet Sitter

A pet sitter can either:

  • Stay overnight at your home
  • Make periodic visits to feed, walk, and check on your dog

2. Ask a Friend or Family Member

Someone familiar to your dog might be willing to:

  • Stay at your place
  • Have your dog stay at their home

3. Use a Boarding Facility or Doggy Daycare

Professional overnight boarding offers:

  • 24/7 supervision
  • Interaction with staff and possibly other dogs
  • Structured activities and regular potty breaks

4. Take Your Dog With You

Many hotels and accommodations are increasingly pet-friendly. It’s worth checking if you can bring your furry friend along!

Maximum Time Frames for Leaving Dogs Alone

According to the HoundGames article, here are the general guidelines for how long you can leave dogs alone based on their age:

Age of Dog (Months) How Long Can Be Left Alone (Hours)
2 3
3 4
6 7
12+ 8+

Even for adult dogs, it’s generally not recommended to leave them alone for more than 8-10 hours regularly. While many adult dogs can physically hold their bladder longer, there are other considerations like boredom, anxiety, and need for social interaction.

Is It Cruel to Leave a Dog Alone Overnight?

This is a question many dog owners struggle with. The HoundGames article addresses this directly, stating: “Leaving a dog alone overnight can potentially be cruel, depending on the dog’s age, health, and temperament.”

It’s really about knowing YOUR individual dog. Some well-adjusted adult dogs genuinely do fine with occasional overnight absences when properly prepared. Others may become extremely stressed or anxious.

What would be considered cruel is:

  • Leaving a dog alone overnight regularly without proper preparation
  • Leaving a dog with separation anxiety alone overnight
  • Not providing adequate food, water, comfort and safety
  • Leaving puppies or dogs with health issues alone for extended periods

Common Concerns About Leaving Dogs Alone Overnight

What if my dog has an emergency?

This is a valid concern! Consider:

  • Having a trusted neighbor who has a key
  • Setting up pet cameras to monitor your dog
  • Having emergency contact info visible in your home
  • Making sure your phone number is on your dog’s ID tag

Will my dog be lonely?

Dogs are social animals, but most adult dogs can handle periodic alone time. To reduce loneliness:

  • Leave something with your scent on it
  • Provide comfort items like their favorite bed and toys
  • Leave soft music or TV on for background noise

What if my dog destroys my house?

If you’re concerned about destructive behavior:

  • Dog-proof the area where they’ll stay
  • Provide plenty of appropriate chew toys
  • Consider crate training (if your dog is comfortable in a crate)
  • Start with shorter alone periods and gradually increase

Gradual Training for Being Left Alone

If you know you’ll need to leave your dog overnight in the future, start training them gradually:

  1. Begin with very short absences (5-10 minutes)
  2. Gradually increase time away
  3. Practice the routine you’ll use when leaving
  4. Monitor their behavior when you return
  5. If they show signs of stress, reduce time and progress more slowly

Final Thoughts

Every dog is unique, and what works for one might not work for another. The most important thing is to honestly assess YOUR dog’s individual needs and temperament.

For many adult, well-adjusted dogs, being left alone overnight occasionally with proper preparation is perfectly fine. For others, alternative arrangements will be necessary.

Remember, if you’re still unsure, consult with your veterinarian or a certified dog behaviorist who can provide personalized advice for your specific situation.

And hey, try not to feel too guilty! We all need to leave our pups sometimes, and with the right preparation, many dogs actually enjoy a little independence. My own dog sometimes seems to enjoy having the couch all to himself when I’m gone! Just make sure you give them extra love and attention when you return.

Alternatives to leaving your dog alone overnight

If you are unable to take your dog with you overnight, consider engaging a dog sitter to look after them when you are away. This could be a friend, a neighbour or a family member but you should ensure that they meet a few times before you leave so that they can get to know each other, the sitter will learn your dogs routine (including how to give them medication, if necessary) and you will be able to see how they interact.

Some sitters will offer to take your dog to their home, which can work very well once your dog gets used to a different environment. Either way, always leave them with a list of emergency contact numbers, including the vet.

Some dogs see their local kennel as a home-from-home and they know what to expect when visiting there. If your overnight absences are fairly frequent, it could be a good option to introduce your pooch to a local kennel when they are young so that they become familiar with it, and they will also learn that you will come and collect them when you return.

Other potential options include the Lhasa Apso, Shar Pei, Miniature Schnauzer, and Bullmastiff, but regardless of breed, a dog needs proper training, socialization, and enrichment like chew toys to prevent boredom and anxiety during extended periods of solitude.
