Energetic Giant Dog Breeds
1. Irish Wolfhound

Irish Wolfhounds are very tall. In fact, they are one of the tallest dog breeds in the world! But they are sweet and playful, even though they look huge and serious. They love people. They love to run. And when they are outside, their energy comes to life.

These dogs were originally bred to hunt wolves. That means they are fast and used to moving through big open spaces. They enjoy long walks. They enjoy short sprints in the yard. If you have a large backyard or like to go hiking, this dog will be a great match.
Inside the home, they are usually calm. But they do need daily movement. Without it, they get bored. And when they’re bored, they may become lazy or sad. They are good with young kids and other dogs. Just make sure they get enough fresh air and fun.
2. Bernese Mountain Dog

The Bernese Mountain Dog is a large and fluffy dog. PetMD states that they were originally bred in Switzerland, where they were used as farm dogs. People used them to pull carts and help herd cattle. That’s why they are strong and love to work.

These dogs are full of energy. They enjoy the outdoors and love cooler weather. If you like hiking, camping, or just walking around the neighborhood, the Bernese will keep up with you.
They are gentle with children. However, because they are large, it’s best to supervise them during playtime. They also need daily activities. Without enough exercise, they may act restless or anxious. Mental games help, too. Give them tasks or puzzles, and they’ll stay happy and balanced.
3. Newfoundland

Newfoundlands are known as gentle giants of the water. They are some of the most active dogs when it comes to water. They were originally bred to help fishermen. That’s why they are great swimmers.

They love to swim, walk, and even pull small wagons. If you live near a lake or have a pool, your Newfoundland will be thrilled. These dogs are strong and love to work. But they also love to cuddle.

They can be calm indoors. But outside, they come alive. Daily walks and water activities are great for them. Just be ready for lots of drool and shedding. Their thick coat needs care.
4. Leonberger

Leonbergers are very large. They have thick fur, a kind face, and hearts full of love. They are a mix of a few giant dog breeds. People originally bred them to be both working dogs and loyal companions.

They are smart and strong. They love games, sports, and anything that involves movement. Many Leonbergers enjoy swimming, running, and agility activities. They also love being part of the family.
These dogs need daily exercise. A walk around the block is not enough. They do best with owners who spend time outdoors. If you give them enough exercise and love, they will be calm, happy, and easy to manage.
5. Scottish Deerhound

The Scottish Deerhound is tall, lean, and very fast. These high-energy breeds were originally bred to chase deer. That means they are made for speed. If you let them loose in a big field, they will run like the wind.

Indoors, they are usually quiet. But outside, they need to stretch their legs and move fast. They are not dogs that enjoy sitting around all day. They love the outdoors and do best in homes with lots of space.
They are gentle and good with other dogs. But they do need a secure yard. If they see something to chase, they might take off. These dogs do best with active families who can give them space and time to run.
6. Great Pyrenees

The Great Pyrenees is a beautiful and powerful dog. The American Kennel Club mentions that this active breed was originally bred as herding dogs to guard sheep from wolves and other predators in the snowy mountains. That means they are alert, brave, and full of energy.

They enjoy long walks and being outside. They are not very playful, but they do enjoy exploring. These dogs need a job to do. They like having a purpose. If they don’t, they can’t get bored. And when they are bored, they might bark or dig.
They are great with families. But they need training and exercise to stay calm. A walk in the morning and one in the evening work best. If you live in the countryside or have a farm, this dog will feel right at home.
7. Tibetan Mastiff

The Tibetan Mastiff looks like a lion. They are huge and very strong. These dogs were originally bred in the mountains of Tibet. Their job was to guard homes and animals.

They are smart dogs and like to work. They enjoy walks and time to play. But they also need mental stimulation. This dog is not for first-time owners. They can be stubborn. But with the right care, they are loyal and loving.
These dogs need a big yard. Small apartments are not ideal. They like to roam and need space. They also need someone who can handle their strong personality. But if trained well, they become great protectors and gentle friends.
8. Bloodhound

Bloodhounds have long ears, wrinkly faces, and a nose that never quits. These dogs were bred to track scents. They are one of the best scent-tracking dogs in the world.

They are always on the move. Always sniffing. Always exploring. They need long walks and tracking games to stay happy. If they don’t get enough activity, they may dig or howl from boredom.
Bloodhounds are friendly and good with kids and other pets. But they must be walked with a leash. Once they catch a scent, they will follow it without thinking twice. A fenced yard is a must.
9. Great Dane

Great Danes are giant dogs with a heart to match. They are tall, gentle, and love to be around people. While they are often seen as lazy, many Great Danes have tons of energy. Britannica mentions that they were originally bred to hunt boars around 400 years ago. That working spirit is still there.

They enjoy long walks, fetch, and sometimes even dog sports. They are smart and easy to train if started young. They love kids and are very social.
