How many hours does dog sleep?

The amount of sleep a dog needs can vary depending on the breed, age, and activity level. However, most adult dogs typically need around 12-14 hours of sleep per day. Puppies and older dogs may need even more sleep, up to 18-20 hours per day. Sleep is essential for a dog's health, just as it is for humans. It allows the body to rest and repair itself, and it also helps to consolidate memories. When a dog is deprived of sleep, it can lead to a number of problems, including irritability, aggression, and difficulty concentrating.
