The dog seems to be sleeping 24 hours a day. Didn't it sleep well at night? Actually, these four reasons

Why Dogs Sleep So Much 

1. Longer sleep: Dogs sleep more than humans because they have stronger bodies and faster metabolism, which requires more energy. They sleep around 10 to 18 hours a day, with larger dogs tending to sleep more. 

2. Ancestral habits: Dogs, like their ancestors the wolves, are nocturnal animals. They naturally prefer to be active at night because it helps them hunt successfully. Although domestication has changed their sleep patterns, they still retain some nocturnal habits. 

3. Boredom: Dogs may also sleep because they are bored. Unlike humans, dogs don't have phones, news, or books for entertainment. Playing with their owners is the best way for dogs to pass time. If they feel bored, they may sleep to fill the void. 

4. Shallow sleep: Dogs mostly have shallow sleep, so they need longer periods to rest. Only when they feel completely secure and relaxed, like when their owners are nearby, can they enter deep sleep. If dogs appear tired all the time, it might be a sign of an underlying health issue. 

Remember, spending quality time with your dog while they are still energetic is important. Observe their sleeping patterns and seek veterinary attention if necessary.
