Can a dog stay home alone overnight?

Most dogs should not be left home alone overnight. A healthy, calm adult dog may get through one night without harm, but a whole night plus the evening before and the morning after is a long stretch with no bathroom break, no one to notice a problem and no one to help if something goes wrong. Whether your dog can handle it depends on their age, health, bladder and how they cope with being alone.

The American Kennel Club’s guidance is a useful benchmark. In its article on how much alone time is too much for dogs, a veterinary behaviorist recommends that dogs spend no more than six to eight hours alone without a chance to relieve themselves. An overnight away, counted from when you leave to when you get back, is usually well past that.

The risks of leaving a dog alone overnight

Most nights would probably pass without trouble. The problem is the night when something does happen and nobody is there.

• Bathroom accidents and discomfort. Holding it for too long is uncomfortable for any dog, and some will go inside, which can upset a house-trained dog as much as it upsets you.
• Stress and separation anxiety. The ASPCA describes separation anxiety signs such as persistent barking or howling, chewing door frames and window sills, digging at doors, trying to escape and pacing. A longer absence gives that stress more time to build.
• Injury or illness with no one to notice. A dog that gets into the trash, swallows something it shouldn’t or gets sick in the night has no one to call the vet.
• Problems in the house. A power outage, a furnace that quits on a cold Colorado night or a smoke alarm going off are all harder on a dog that is alone.
• Missed meals and medication. If your dog eats twice a day or takes medicine on a schedule, a night away usually means something gets skipped.

Puppies, seniors and dogs with medical needs

For some dogs the answer is a clear no.

• Puppies. The AKC’s guide to how long you can leave a puppy alone notes that very young puppies can’t hold their bladder for long, and the time grows slowly as they get older. Puppies also chew, explore and get into trouble. They need someone there.
• Senior dogs. The same AKC guide says senior dogs may need to go out more often. Older dogs can also be stiff getting up, confused at night or slower to recover from a fall.
• Dogs with medical needs. A diabetic dog’s meals and medication need to stay on schedule. Dogs with seizures, heart problems, cancer or recent surgery can change quickly. A blind or deaf dog depends on a steady routine and a familiar person.
• Anxious dogs and new rescues. If your dog already struggles when you leave for a few hours, a whole night alone is likely to make it worse.

If your dog is in any of these groups, talk with your veterinarian before you plan time away, and plan for someone to be with them.

When drop-in visits are enough

Drop-ins can work well for some dogs on some trips. They tend to fit when your dog is a healthy adult, is relaxed being alone during the day and sleeps through the night without needing to go out. They also fit short gaps, like a late evening or an early flight, rather than full nights away.

Even then, a single visit a day is rarely enough for a dog. Plan visits so the longest stretch alone stays within what your dog is used to. Hope’s drop-in visits follow your dog’s written routine, and you get a text and photo after every visit, so you can see how your dog is doing.

When an overnight sitter is the better choice

An overnight sitter makes more sense when your dog is a puppy, a senior or on medication, when they get anxious alone, when you’ll be gone more than a night or two, or when you would simply lie awake wondering. Your dog keeps their own bed, food and routine, and someone is there for the late walk, the early walk and anything that happens in between.

With Hope’s overnight pet sitting, Hope or one of the sitters she trained sleeps at your home and follows a written care plan made at a free walkthrough before the first booking. You’ll know who’s coming before the stay starts. You get at least one text and photo every day, and first-time clients get a morning and an evening update. The rate is $120 a night for one dog, and new clients pay $100 a night for their first stay. For more pets or a longer trip, the house sitting cost calculator gives you an estimate.

If you have to leave your dog alone

Sometimes there is no other option for one night. If that happens, lower the risk as much as you can:

1. Ask a trusted neighbor to let your dog out late in the evening and early in the morning.
2. Leave plenty of fresh water and a safe, familiar space, with trash, food and anything chewable put away.
3. Give a long walk and a meal at the usual time before you go.
4. Leave your vet’s number and your contact details where a neighbor can find them.
5. Keep it to one night, and don’t make it a habit.
