One of the laziest and most laid-back dog breeds is the English Bulldog. Often referred to as a couch potato, the English Bulldog is not an active breed, and these dogs require little maintenance in terms of grooming, training and exercise.
The Bullmastiff is another dog that has a laid-back and somewhat lazy demeanor, although it is massive in size. It is not easily roused, and it is bred not to attack but to guard and knock perpetrators down. The massive and muscular Bullmastiff is not energetic, and it enjoys lying on the floor or couch for the most of the day.
