Large – Breeds that range from 55-85 pounds Some people live by the motto “bigger is better,” and it extends to their dogs, too. Despite their massive size, they’re actually wonderful to live with as most prefer to relax all day and are relatively calm inside the house. Large does are well suited to suburban or country living because that means more space for them to sprawl. But apartment dwellers need not worry: Many large dogs are more than happy to sleep all day as long as you give them daily exercise to work off their energy. Since they were originally bred to be hunters and have a natural instinct to guard and protect, regular activity is a must.
