Orvis mentions that this heavily misunderstood canine makes incredibly good-natured family pets, police dogs, and search and rescue operators.
The Rottweilers gained their strength by driving livestock and pulling heavy carts. They are athletic dogs that thrive on daily exercise. They especially enjoy activities like swimming, walking, and trotting; always happiest when they can stay active alongside their people.
Fun Fact
The Rottie’s career in livestock ended with the rise of the railroad cattle cars in the 1800s. They found a new job as police dogs, personal protectors, and all-around blue-collar dogs capable of performing various heavy-duty tasks.
Rotties were also among the first guide dogs for the blind, and in more recent times, they distinguished themselves as search-and-rescue workers at such disaster sites as Oklahoma City and the World Trade Center.
Conclusion
These huge dogs with recognizable strength and hard-built bodies are mistakenly seen as dangerous, aggressive, and daunting dog breeds. But in truth are big-hearted softies who love their owners exponentially. Some of these puppies might have a strong prey drive due to their hunting dog background (like in Rhodesian ridgebacks and Siberian huskies), while other dogs have their muscular physique gifted to them due to an inherited recessive trait, which is the case in Bully and whippets.
But most muscular dog breeds have their unique physique due to their highly intensive careers, which involve pulling carts, hauling heaving weights, and running for miles on end to deliver freight. Other honorable mentions of dogs with a solid frame involve the Olde English bulldog, the American pit bull terrier, the American bully, bull terriers, the bully kutta, the cane Corso, the German shepherd, American Staffordshire terriers, and the Doberman pinscher.
