It is normal for dogs to love sleeping. Dogs are born to love sleeping, especially young and old dogs.

Dogs sleep to replenish their physical strength and relieve fatigue. They need 13 to 16 hours of sleep every day, but dogs generally spend very little time sleeping, probably only about 4 hours. Therefore, when you raise a dog at home, you will find that it sleeps and dozes outside of eating, drinking and playing. However, if your dog sleeps more than usual and is accompanied by a loss of appetite, vomiting and diarrhea, it is probably due to a disease in the body.
