How Many Hours Should an Old Dog Sleep? A Vet’s Answer

“How many hours should an old dog sleep?” If you are looking over at your snoozing senior dog and asking yourself this question, integrative veterinarian Julie Buzby is here to help. By the end of this article, you’ll have guidelines for how long dogs may sleep, signs that your dog’s sleep patterns may indicate a problem, and tips to help your dog sleep more comfortably.

One common question I get asked by senior dog parents is, “How many hours should an old dog sleep?” It is normal for pet parents to become concerned when they notice their beloved older dog is sleeping more and more. Or, on the flip side, when they notice their dog seems to pace around all night long.

Since I frequently discuss this with my clients, I wanted to share this information with you too. Understanding what’s normal and what’s not can make it easier for you to know if the changes you are seeing could be pointing to a problem. Let’s start by establishing a baseline.

How many hours do dogs sleep at each age?

Just like humans, dogs have varying sleeping habits based on their age. It may not surprise you that similar to babies and elderly folks, puppies and older dogs need the most sleep.

How much do puppies sleep?

Puppies are busy developing, growing, and learning. All this hard work means that puppies sleep most of the day. Young dogs under one year old should sleep an average of 18 hours a day.

But just like human toddlers, puppies might need reminded that they need to stop moving and fall asleep. Crate training your puppy can be a great way to help with this. The crate can serve as a comfortable, quiet, and familiar spot to allow your puppy to relax and sleep.

How much do adult dogs sleep?

Adult dogs (ranging from one year old to about five or six) will sleep 8 to 14 hours a day. The amount of time that an adult dog sleeps will vary depending on age, breed, and activity level. For example:

• Younger adult dogs will probably sleep less than those closer to senior age.
• Medium breed dogs usually need less sleep than others.
• Large breed dogs sleep more during the day.

Dogs who are very energetic and working dogs will sleep less during the day. They are too busy and have too much adrenaline to take a nap. But come nighttime, these dogs will be worn out, so they typically sleep soundly through the night.

On the other hand, dogs who are couch potatoes or spend their time lying around are going to doze throughout the day. Since they have spent more time sleeping in the daylight hours, some of these dogs might be restless at night. However, if your dog is a sleep-aholic like my dog, he or she might happily nap all day and still sleep at night.

Finally, dogs who are left alone for longer periods of time will likely spend more hours asleep. With their family gone, they can take advantage of the quiet house and “catch some Z’s.” The exception to this would be dogs who suffer from separation anxiety. Since they tend to be restless or anxious when left alone, they will probably not sleep the day away.

How many hours should an old dog sleep?

Most dogs’ sleep patterns usually begin to change between five and seven years old. As dogs get older, their energy level starts to decrease. They need more sleep to recharge and be at their best during the day. For this reason, it is normal for a senior dog to sleep up to 20 hours a day. This can definitely make it feel like your old dog sleeps all day.

Why do old dogs sleep so much?

Granted, every dog (and human) needs sleep in order to function. But for senior dogs, there are five main reasons that explain why they sleep a lot:

1. As dogs age, they tire easily and need more time to rest and catch up. Taking multiple naps throughout the day allows the body to relax and prepare for more activity.
2. Sleep is very important for immune health. Sleeping for longer periods of time can help your senior dog’s body prevent infections.
3. When dogs get older, they often become more restless. The interrupted sleep at night and senior dog anxiety at night can cause them to be more tired during the day.
4. Senior dogs are more likely to be suffering from joint pain or other diseases that makes sleep uncomfortable. This can lead to the need for more naps since their sleep quality is poor. Sleeping can also be a way for them to try to “escape” their pain and discomfort.
5. Older dogs have an increased risk of developing several diseases that can cause them to be a lethargic dog. Sudden changes in sleep patterns could be a sign that your dog is suffering from an underlying condition.

What are the warning signs of a problem?

I want to take a bit of time to focus in on number five on the list. It is true that for your senior dog, sleeping more during the day can be a normal part of aging. But, it could also be an indication that there is something wrong. And herein lies the root of my clients’ concerns about sleep habits.

When faced with a dog who may be sleeping excessively or not sleeping enough, I often ask the dog parents a few questions:

1. Was the change in your dog’s sleep pattern sudden or gradual?

I usually suggest watching for sudden, unexpected changes in a dog’s sleep schedule as it tends to be a bigger red flag. For example, if your 8-year-old dog loves to go on walks every day and suddenly doesn’t have the energy to leave the house, there is likely something causing this change. But, if your dog has been sleeping more and more over the years and has gradually worked up to sleeping all day, this is more likely to be normal.

2. How does your dog act while sleeping?

Like us, dogs may dream while sleeping. You may see your dog twitching, shaking, or even running in his or her sleep. It is also normal for dogs to occasionally whimper, cry, bark, howl, or growl in their sleep. As long as your dog seems relaxed, these occasional noises or movements can be normal.

However, if you believe that your dog is in pain while sleeping, please discuss it with your veterinarian. Taking a video of your dog sleeping can be helpful for your vet to see what your dog is doing. It is also a good way to ensure that your dog is not having an old dog seizure rather than dreaming.

3. How does your dog act when awake?

Additionally, it is important to take other habits and symptoms into consideration. Does your dog have good energy when awake, normal appetite, good bathroom habits, and his or her typical personality? If yes, then your dog is probably just getting older and slowing down. If no, then this could be a sign of a problem.

4. Are you noticing other concerning symptoms?

If your dog is sleeping all the time (or barely sleeping at all) and has some abnormal clinical signs, it could be an indication of a health issue. Other symptoms to watch for include:

• Decreased or increased appetite
• Decreased water consumption or increased thirst in dogs
• Vomiting or diarrhea
• Sudden weight gain or loss
• Lethargy or dullness
• Abnormal urination and defecation (including accidents in the house or pooping or peeing while sleeping)
• Changes in hair coat (dull, dry, brittle, patchiness, etc.)
• Bloating or abdominal distention (i.e. a pot-bellied dog)
• Difficulty breathing or a dog who is breathing fast or heavy (either while awake or asleep)
• Old dog coughing or gagging
• Wandering or restlessness (especially in the middle of the night)
• Signs your dog is in pain

If you have any concerns about your dog’s sleeping habits or you’re seeing some of these signs, please make an appointment with your veterinarian.

How will the vet figure out what is going on?

Once you arrive at the vet’s office, the veterinary team will ask you questions to understand what changes you are noticing at home. Then your vet will perform the physical examination and closely look at your dog. Depending on the symptoms and the results of the exam, your vet might recommend diagnostic tests such as:

• Bloodwork and a urinalysis to look for signs of diabetes, Cushing’s disease in dogs, hypothyroidism in dogs, kidney failure in dogs, liver disease in dogs, anemia in dogs, and other disease conditions.
• X-rays or ultrasound to evaluate the heart for signs of heart disease in dogs, the spleen for splenic masses in dogs such as hemangiosarcoma in dogs, and other organs such as the liver, kidneys, and GI tract for signs of enlargement, abnormalities, or tumors.
• An orthopedic exam to look for osteoarthritis in dogs, hip dysplasia in dogs, IVDD in dogs, torn ACL in dogs, or other reasons that a dog may be lying down more or struggling to walk or stand.
• A canine cognitive dysfunction checklist to evaluate for signs of dementia in dogs (i.e. sundowners in dogs), which can cause a dog to be awake and restless at night and sleeping all day.

If the diagnostics confirm that there is a specific disease causing your dog to sleep more, your veterinarian will discuss appropriate treatment and prognosis with you. Or if the results are normal and your dog is deemed healthy, your veterinarian might discuss how to monitor your dog for any changes.

Additionally, especially if the problem was that your dog isn’t sleeping well at night, the vet may also talk to you about how improve the quality of your dog’s sleep.

How can I help my old dog sleep through the night?

Getting proper sleep is necessary to maintain good physical, mental, and emotional health, and to prevent infections and other diseases. Therefore, it is important that your dog is comfortable and able to sleep deeply. I share these tips with my clients and wanted to pass them on to you too:

1. Create a comfortable sleeping environment

If your dog is struggling to get comfortable, consider adjusting where he or she sleeps. Senior dogs who sleep on their parents’ beds might need stairs or a ramp to get on and off the bed safely. Or they may start to prefer having their own comfy bed on the floor. That way they don’t have to climb or jump to find a good place to sleep.

Also, dogs who have arthritis or other painful diseases can benefit from an orthopedic dog bed that is cushioned, supportive, and protects their joints. There are many different materials (e.g. egg crate foam, memory foam, etc.), shapes, thicknesses, and covers to consider when it comes to choosing a dog bed. And just like humans, every dog is different. It can take some trial and error to figure out what bed is best for your pup.

2. Add some ambiance

I have heard clients say that their dog needs a night-light or quiet music to help them sleep. Or other dogs actually prefer to sleep in their kennels instead of on a bed because they feel safe and protected there. It is all about what works for your dog.

3. Control your dog’s pain

Pain can make it difficult for a dog to sleep, no matter how nice the bed and environment are. If your dog seems to be stiff, uncomfortable, or you are seeing other signs of pain, please talk to your veterinarian.

There are a wide variety of options for natural pain relief for dogs like Dr. Buzby’s Encore Mobility™ hip and joint supplement. Plus, your vet can also prescribe pain medications like non-steroidal anti-inflammatories, gabapentin for dogs, tramadol for dogs, or amantadine for dogs.

4. Increase mental stimulation, activity, and mobility during the day.

If your dog wants to sleep all day and stay up all night, sometimes you can help “wear him or her out” for better nighttime sleep. Try taking your dog on a walk or dog wagon or dog stroller ride so that your dog is more tired come evening. Or consider giving him or her puzzle toys or playing brain games for mental stimulation.

Additionally, applying Dr. Buzby’s ToeGrips® dog nail grips can help your senior dog confidently walk around the house without fear of slipping on the floor. This may make him or her more likely to get up and engage with life during the day instead of sleeping all the time.

5. Talk to your vet about medications or supplements to promote nighttime sleep.

Especially if your dog has canine cognitive dysfunction and sleep-wake cycle disturbances, he or she may benefit from some sleep-aids. One great option is melatonin for dogs. This natural supplement can promote sleep and help establish a good sleep-wake cycle. However, it is important you check the label of the melatonin supplement to ensure it does not contain xylitol (i.e. birch sugar), which is toxic for dogs. Unfortunately, this dangerous sugar substitute is found in some melatonin products, especially gummies.

Additionally, some dogs who become anxious at night may benefit from trazodone for dogs, an anti-anxiety medication with mild sedative activity. If you think that your dog might be a good candidate for these (or other) medications and supplements, please talk to your veterinarian.

Work with your veterinarian

As a dog parent, it can be difficult to watch your dog approach his or her golden years. There are a lot of changes that accompany aging, including the changes in sleep pattern that we have discussed here.

In short, I want you to keep in mind that increased sleep is a normal part of being a senior dog. But if the change occurs suddenly, your dog is having trouble sleeping at night, or you are seeing any worrisome symptoms, it is best to check in with your vet. That way, if there is a problem, you and the vet can promptly create a plan to address it. And if everything is normal, you can rest a bit easier as you look over at your sleeping dog.
