Why Is My Dog Sleeping More During the Day?
Increased daytime sleep is often normal—especially in puppies, seniors, or dogs with low energy levels. However, sudden or extreme changes may indicate health problems like thyroid issues, heart conditions, or canine cognitive dysfunction (CCD). Monitor for other symptoms and consult a vet if needed. - Puppies and senior dogs need more sleep than adults. - Dogs typically nap 3–4 hours daily; older dogs may nap longer. - Sudden changes in sleep patterns warrant a vet visit.
Normal Sleep Patterns in Dogs
Dogs spend about 80% of their day sleeping or lounging. On average, they sleep around 8 hours at night and nap for about 4 hours during the day. This includes both deep sleep and lighter resting periods. Puppies and senior dogs require more sleep than young adult dogs, with older adults sleeping up to 3 hours and 59 minutes during the day, and seniors sleeping around 4 hours and 12 minutes.
Age and Sleep Needs
Sleep needs vary by age. Puppies and senior dogs naturally sleep more than young adults. A study found that older adult dogs slept about 3 hours and 59 minutes during the day, while senior dogs slept around 4 hours and 12 minutes. These changes are normal as dogs age, similar to how human sleep patterns shift over time.
When Increased Sleep Is a Concern
While increased daytime sleep is often normal, sudden or significant changes may signal an underlying health issue. Conditions like heart disease, thyroid problems, or canine cognitive dysfunction (CCD) can disrupt a dog’s sleep-wake cycle. Dogs with CCD often sleep more during the day and become restless at night due to changes in their circadian rhythm.
Signs of Canine Cognitive Dysfunction (CCD)
CCD, similar to Alzheimer’s in humans, can cause confusion, anxiety, reduced interest in interaction, and disorientation. One key sign is disrupted sleep—dogs may nap excessively during the day and be awake and agitated at night. If your dog shows these symptoms alongside increased daytime sleep, a vet visit is recommended.
Supporting Healthy Sleep Habits
To help your dog sleep well, ensure they have a comfortable bed, a consistent routine, and quiet time during the day—especially in busy homes. Regular daytime activities like walks, play, and socializing (about 90 minutes of walking/exploring and 120 minutes of watching you or sniffing around daily) support healthy sleep. After training or activity, a good night’s sleep helps with memory and learning.
Frequently asked questions
Should I worry if my senior dog sleeps more during the day?
Not necessarily—senior dogs naturally need more sleep. But if the change is sudden or accompanied by confusion or restlessness, consult a vet.
Can stress affect my dog’s sleep?
Yes. Stressful environments or new locations can disrupt sleep. Providing a calm space and familiar bedding helps.
