Yes, Newfoundlands sleep a lot. Newfoundlands sleep 12 to 14 hours a day.
Most other dog breeds sleep an average of 10.8 hours a day — almost 2 hours less than the average Newfoundland.
Newfoundland puppies sleep even more than adult Newfoundlands, sometimes up to 20 hours a day.
Even though Newfoundlands sleep a lot, they are not actually lazy dogs. They will still get up and play or exercise with you if you set up a regular schedule and train them well.
